| 01:28.14 | hno | hi hi |
| 01:28.21 | Boulet | wow, still awake |
| 01:28.28 | hno | not really |
| 01:28.40 | Boulet | hehe |
| 01:29.29 | hno | but some errors in test1 squashed, like parameters taken from A10 and not A13 and bus clock divisors wrongly set, but still no go on my board. |
| 01:29.57 | Boulet | ah cool |
| 01:30.16 | Boulet | i just replaced that &= by an = |
| 01:31.07 | Boulet | you use the olimex board ? |
| 01:31.18 | Boulet | all this works on my 4 different A13 PCBs |
| 01:32.16 | hno | Well, test1 works, and writing/reading to DRAM works. But booting Linux fails. |
| 01:33.52 | hno | https://github.com/hno/Allwinner-Info/commit/21b2809a87486f169b15795309cffdd0debd4917 is the changes made to clock setup by comparing with register rsults when u-boot is loaded from nand. |
| 01:34.27 | Boulet | thanks |
| 01:35.36 | Boulet | oh that DRAM_CCM_SDRAM_PLL_TUN_REG, i have no idea what it does |
| 01:36.27 | hno | Neither do I, and the write does not seem to be effective either. The bits that differ are reserved according to the register file. |
| 01:37.58 | hno | Both AXI and APB0 clock divisors was wrongly set. |
| 01:40.06 | Boulet | so the cpu runs at what frequency ? |
| 01:40.23 | Boulet | 24*8*4/1/16 ? |
| 01:40.47 | Boulet | oh wrong |
| 01:41.48 | Boulet | sorry |
| 01:43.44 | Boulet | 24*21*1/1/1 |
| 01:49.42 | Boulet | this calculation is wrong |
| 01:49.55 | Boulet | seems like the CPU runs indeed at 1008 MHz after our PLL1 config |
| 01:50.40 | Boulet | in the kernel mach-sun5i\clock\ccmu\pll_cfg_tbl.c |

| 01:51.08 | Boulet | 21,1,0,0 corresponds to 1008MHz |
| 01:52.30 | Boulet | i think the formula is 24*N*(k+1)/(M+1)/(P+1) ? |
| 01:57.03 | hno | p=1/2/4/8 |
| 01:57.19 | hno | n=N |
| 01:57.39 | hno | k=K+1 |
| 01:57.48 | hno | m=M+1 |
| 01:58.28 | Boulet | ah P can only be 1/2/4/8 ? 0->1 1->2 2->4 ... ? |
| 01:58.40 | hno | yes |
| 01:58.43 | Boulet | ok |
| 01:59.06 | Boulet | and that K+1 explains why i saw 2x more than expected from the test1 comment |
| 01:59.32 | Boulet | btw, i tried 1200MHz, seems fine too ;) |
| 01:59.36 | hno | Not sure if it's really n=N. Documentatin says it is, but it's +1 on other PLLs. |
| 02:01.47 | hno | but not all.. |

| 03:54.03 | furan | turl sorry to bug you but did you start a repo? |
| 03:54.51 | furan | I am about to solder a nand socket to an mk802 and upgrade the nand to different types to see if I have the way the nand table works worked out |
| 03:56.08 | Turl | furan: yeah, just didn't make a local manifest for it yet though |

| 03:58.12 | furan | what do you mean by local manifest? |
| 03:59.09 | furan | (I'm still working out android stuff) |
| 03:59.20 | furan | nm googled |
| 04:00.17 | Boulet | furan, interesting |
| 04:00.34 | Boulet | do you have an external nand programmer also? |
| 04:01.11 | furan | no, but i've gotten livesuit to the point of being able to flash it (have to modify the nand table in the files in the image that livesuit loads into memory to do the flash) |
| 04:01.36 | furan | last time I tried this I just didn't have the values worked out, since they didn't match the datasheets |
| 04:02.14 | furan | also I'm worried that since brom reads the first page it might have hardcoded nand support, in which case with new nand you might have to always boot from a u-boot sdcard that jumps to nand |
| 04:04.09 | Boulet | what do you mean by "hard-coded" support ? |
| 04:04.26 | furan | well, brom executes code that reads the first page of nand and then executes code on the nand |
| 04:04.35 | Boulet | yeah |
| 04:04.48 | furan | so that code in brom may have fixed support for nand, since nand can have different read commands (it generally doesn't, but it can) |
| 04:05.08 | furan | e.g. the brom code may have its own table that it references to understand how to read the first page depending on nand id |
| 04:05.16 | Boulet | there are some universal read commands though |
| 04:06.06 | Boulet | that's possible yeah |
| 04:06.17 | furan | are there? for some reason the nand driver keeps a table of 'architectures' with nand read/write/etc commands for each arch |
| 04:06.37 | furan | I'm learning about talking to nand at the same time |
| 04:06.44 | Boulet | i think to remember there are basic read commands that every nand support |
| 04:06.55 | furan | that would be good |
| 04:07.19 | Boulet | but then, there is ECC correction, and that is a different story |
| 04:07.36 | Boulet | and also flashes can have different planes, can be SLC or MLC, blah blah blah |
| 04:07.45 | furan | yeah. |
| 04:07.59 | Boulet | but i think reading the first block should not be too difficult in an universal way |
| 04:08.31 | furan | how big is the read? I suppose if it is smaller than the smallest page size it might work |
| 04:08.34 | Boulet | ECC depends on the chip controller, so A10 will expect to find its own ECC scheme on the nand flash |
| 04:08.44 | Boulet | i don't know |
| 04:09.08 | furan | a10 nand driver keeps an 'ecc' field for each supported nand chip, I'm still confused about that one. might be num bits |
| 04:09.30 | Boulet | i programmed a flash controller 5 years ago on a DSP chip, it was SLC NAND, 64 pages of 2048+64 bytes per page |
| 04:09.38 | furan | cool |
| 04:09.56 | furan | what is the +64, to account for bad blocks? |
| 04:10.04 | furan | I noticed the page size+number in a lot of dataasheets |
| 04:10.12 | furan | usually that number grew with the page size |
| 04:10.17 | Boulet | those are used to store ECC values and other info that might be useful for your filesystem |
| 04:10.23 | furan | I see |
| 04:10.24 | Boulet | like logical to physical block translation |
| 04:10.43 | furan | nods |
| 04:10.53 | Boulet | some nand datasheet call this "spare", but on linux it's called oob data i think |
| 04:11.32 | furan | ok |
| 04:11.33 | Boulet | so when you read/write a page thru the NAND flash controller of A10, it should be able to calculate/apply ECC automatically |
| 04:12.01 | Boulet | which is great, because doing ECC in software is quite costly |
| 04:12.24 | Turl | hipboi: the kernel land changed quite a bit :P |
| 04:12.36 | furan | nods |
| 04:12.36 | hipboi | not that much |
| 04:12.50 | furan | is there an mk802 android depot, or some way for me to just pull the device config for mk802? |
| 04:12.55 | Boulet | you imagine, you have 2048 bytes, with a few extra bytes, you are able to locate and correct up to 8 (let's say) bits in those 2kb :) pretty cool |
| 04:13.15 | Turl | hipboi: the diff is quite big, they refactored quite a bit of things |
| 04:13.29 | hipboi | oh, yes |
| 04:13.30 | furan | nods |
| 04:14.04 | hipboi | btw, the rar is provided by my workmate |
| 04:14.39 | Turl | hipboi: is he the one that sells devices with you? |
| 04:14.50 | hipboi | no |

| 15:28.45 | rm | Rikomagic came out and listed in pictures and block diagrams why MK802 sucks |
| 15:29.01 | rm | compared to this new wonderful MK802 II :) |
| 15:29.48 | RaYmAn | so basically they made it safe? :P |
| 15:30.01 | popolon | specing, sorry for citing phoronix :d |
| 15:30.37 | specing | rm: lol, since when is the AXP 209 "power protect IC"? |
| 15:31.10 | rm | no idea :) |
| 15:31.16 | popolon | but this means some more application could be run on arm platforms, even if perfs are far behind today |
| 15:31.18 | specing | look at the images! |
| 15:31.20 | rm | they just list in so much detail all the differences |
| 15:31.32 | rm | saying "look this one is so much better than the old one" |
| 15:31.35 | specing | popolon: phoronix is full of shit, to summarize |
| 15:31.49 | xxiao | i assume mk802ii ricomagic is using rockchip? |
| 15:32.02 | rm | which translates into "the old one sucks" -- "oh, and we're still selling it, btw" |
| 15:32.10 | rm | xxiao, A10 |
| 15:32.18 | popolon | specing, largly agry |
| 15:32.56 | popolon | I still have it in my rss agregator to obtain some links |
| 15:33.40 | specing | rm: They've sure added a huge antenna, too |
| 15:34.51 | specing | rm: they old one may fry your TV, but atleast you save $10 |
| 15:35.32 | rm | actually the old one is more expensive in their store :) |
| 15:35.55 | rm | also, you connect your MK802 to a TV, what kind of savage you are? |
| 15:36.02 | rm | everyone knows MK802 is a server platform :P |
| 15:36.04 | specing | I don't have one |
| 15:36.10 | rm | or for DIY automation |
| 15:36.11 | rm | :D |
| 15:36.27 | rm | speaking of which |
| 15:36.35 | rm | are there any simple USB-to-GPIO dongles? |
| 15:36.36 | specing | I have real stuff (100+ io) for automation |
| 15:36.42 | RaYmAn | yeah, it's just great for dyi automation with all the gpios it has ;) |
| 15:36.43 | rm | 1 USB in 30 GPIO out |
| 15:36.54 | RaYmAn | olinuxino would probably be a better match =P |
| 15:36.55 | specing | rm: USB avr ;) |
| 15:37.17 | xxiao | everyone keeps its graphic lib and vpu lib proprietary these days, if kernel is not upgrade, for that matter, the user space glibc etc are the same, will that work? |
| 15:37.42 | xxiao | s/upgrade/upgraded/ |
| 15:38.19 | xxiao | of course we can recompile the kernel, just no big upgrade/downgrade |
| 15:38.40 | hno | Heh, MK802 II adresses the concerns raised when we first saw the MK802.. undoing their shortcuts / cost saving attempts and add back what should be there. |
| 15:39.43 | hno | the old is't dangerous to the tv, it's the reverse. the tv is a angry monster. |
| 15:40.36 | hno | and the AXP is a far better power regulator & controller than the simple design they used before. |
| 15:41.56 | hno | The old unit was also prepared for HDMI ESD protection, but they left it out in production. Same might happen with II. |
| 15:42.03 | rm | hno, just kind of surprising they officially list ALL of this in such detail, in photos, comparison tables, etc etc |
| 15:42.33 | rm | one would think they'll try to turn attention away from the fact they cut costs in the first mk802 by omitting some safety guards |
| 15:43.23 | hno | rm, is that the official rikomagic store run by rikomagic? |
| 15:43.26 | xxiao | with this new design the cost is the same or lower? |
| 15:43.40 | xxiao | it's $66 |
| 15:43.40 | hno | production cost is higher. |
| 15:44.12 | xxiao | is thinking about buying one mk802-II |
| 15:45.00 | xxiao | really, olimex should do a kickstarter to get some A10 out quicker |
| 15:46.37 | rm | it says "Rikomagic MK802 family Store" |
| 15:46.38 | hno | olimex is doing their A10 board on their shedule. kickstarter would not help |
| 15:46.49 | rm | and it has the most orders for the MK802 II of all stores |
| 15:46.53 | rm | so I assumed it was |
| 15:46.54 | rm | maybe not |
| 15:47.06 | hno | do they link to it? |
| 15:47.36 | rm | did not check |
| 15:47.41 | *** join/#arm-netbook simonckenyon (~kvirc@195.7.61.8) |
| 15:47.55 | rm | but given how chinese websites roll, I wouldn't be surprised if they didn't link to it even if it was theirs |
| 15:52.08 | hno | Eh? rikomagic ownenglish specifications: Graphical processor: 2D/ 3D/ OpenGL ES2.0(AMD Z430)/ OpenVG1.1(AMD Z160)@27M Tri/sec |
| 15:54.29 | hno | rm, yes, might be theirs. |
| 15:55.34 | hno | Contact person is Michelle Ding for both. |
| 15:59.56 | hno | interesting, there is a large connector not mounted close to mUSB port. Can't make out what is printed next to the pads in the picture |
| 16:02.13 | popolon | there is a full USB port & 2microUSB |
| 16:02.19 | popolon | full sized |

| 16:07.31 | popolon | liliputing people guy wrote that The DC adapter blew up during first use |
| 16:07.33 | popolon | :) |
| 16:08.36 | hno | popolon, yes, AC adapters is often sub-standard on chineese products. |
| 16:09.35 | hno | rikomagic "cheats" and do not include one, being powered by USB |
| 16:09.52 | rm | they don't now? |
| 16:10.22 | hno | In the II? |
| 16:10.50 | rm | yep, looks like II-nd doesn't include it |
| 16:11.00 | rm | that sucks |
| 16:11.17 | popolon | most electronic devices use USB in China now, and you find lot of DC=>USB adapter |
| 16:11.25 | rm | sure |
| 16:11.29 | rm | but it's +$4 |
| 16:11.37 | rm | and from a separate store/etc |
| 16:11.50 | popolon | I bought one for less than that if I'm not wrong ? |
| 16:12.05 | popolon | in a Xiamen phone house |
| 16:12.24 | hno | USB cable. USB otg converter cable, HDMI extension cable |
| 16:12.29 | popolon | abotu 1€ if I remember |
| 16:12.35 | rm | that's cheap |
| 16:12.44 | rm | did it not blow up on first use? :D |
| 16:13.53 | hno | why do all sticks insist on male HDMI connectors? Just include a male-male plug if needed... |
| 16:14.00 | popolon | still didn't tried it :) |
| 16:14.19 | popolon | my phone usb connector is dead |
| 16:14.29 | popolon | so I bought a universal battery charger |

| 16:14.54 | rm | I got one with some usb ports and a microUSB cable included for $4 from DX recently |
| 16:14.58 | rm | for a Raspberry Pi |
| 16:15.01 | rm | which I don't have |
| 16:15.16 | Turl | rm, eMMC is kinda nand connected via standard interface I believe :P |
| 16:15.41 | rm | Turl, point is, it should be replaceable w/o throwing away the whole board |
| 16:16.21 | Turl | rm: that's SD cards :P |
| 16:16.23 | rm | why do you think people (me) aren't in a hurry to have their custom distro's root FS moved to internal nand |
| 16:16.30 | popolon | the charger was ~3€ if I'm not wrong |
| 16:16.34 | rm | because the damn nand is soldered in there |
| 16:16.40 | rm | wears out, game over |
| 16:16.45 | hno | Turl, eMMC is like SD packaged in BGA module. |
| 16:17.22 | hno | often with 8-bit MMC bus. |
| 16:18.08 | hno | SD cards have 4-bit bus. |
| 16:22.25 | Turl | :) |
| 16:23.25 | hno | You can't replace an eMMC unless you are good at reflowing small size BGA |
| 16:27.58 | netchip | Turl: Does the mali blobs hoiboi gave you work for ALL Mali400 chips? |
| 16:28.30 | Turl | netchip: no, they're device specific |
| 16:28.55 | netchip | hmm |
| 16:29.06 | netchip | Do you think he's willing to make then for the SGS3, i9300? |
| 16:29.47 | Turl | seriously doubt it |
| 16:30.06 | Turl | I'm betting the DDK takes some device glue too like the kernel space |
| 16:30.14 | Turl | and he won't have samsung's glue anyway |
| 16:32.20 | netchip | t |
| 16:32.39 | netchip | Turl: :/ |
| 16:33.29 | WarheadsSE | Turl: which ump/xf86 was the kernel prepped for? |
| 16:35.00 | Turl | WarheadsSE: idk |

| 16:36.10 | netchip | t |
| 16:40.24 | WarheadsSE | mmm, problematic Turl |
| 16:53.01 | hno | I don't know why ARM made MALI drivers this mess. It's a maintenance nightmare. |
| 16:54.11 | WarheadsSE | haha |
| 16:54.19 | WarheadsSE | only if you use anything other than 2.6.38 |
| 16:54.23 | WarheadsSE | >.< |
| 16:55.43 | hno | no seriously, it is a complete mess even if you use 2.6.38. There is tight bonds SoC hardware <-> kernel driver version <-> userspace component. |
| 16:56.00 | WarheadsSE | I've reviewed the code |
| 16:56.10 | WarheadsSE | why do you think I hate them using xorg 1.11 so much ? |
| 16:56.24 | WarheadsSE | If I can get a stable interface, Id be happy. |
| 16:56.30 | WarheadsSE | Right now, thats not the case. |
| 16:57.04 | RaYmAn | Are there *any* arm socs without that issue? |
| 16:57.13 | WarheadsSE | with r2p4 I can almost get a stable interface, until I get a deep-kernel null pointer |
| 16:57.22 | RaYmAn | Tegra is definitely at least as bad - they change the userspace <-> kernel interface constantly (though, finally getting better) |
| 17:00.01 | jelly-home | RaYmAn: well, there's a reason Linus gave them a finger |
| 17:00.07 | jelly-home | the* finger |
| 17:00.27 | hno | hopes Linus still have his fingers intact |
| 17:14.18 | Turl | who wants to review the new mali stuff? :P |
| 17:14.19 | Turl | https://github.com/allwinner-dev-team/linux-allwinner/commits/wip/allwinner-3.0/mali-2 |
| 17:14.26 | Turl | 2nd, 3rd commit |
| 17:14.40 | Turl | + finally ARM did decent Kconfig/Kbuild scripts to be built inline |
| 17:14.48 | Turl | so our CONFIG_MALI is obsolete |
| 17:15.06 | Turl | and all the places where we use it needs to be changed :P |
| 17:18.28 | netchip | What's the improvement of r3p0 over r2p4? |
| 17:18.35 | netchip | yea it's rewritten |
| 17:18.39 | netchip | but further more? |
| 17:20.26 | Turl | ask ARM :P |
| 17:22.27 | furan | sup |
| 17:23.59 | WarheadsSE | added openVG |
| 17:24.16 | furan | hno: justs seeing these bga emmc devices for the first time, cool |
| 17:24.17 | WarheadsSE | and wned up with a bajillion symlinks all to libMali.so |
| 17:39.23 | xxiao | anyone aware of an 3.3v-rs232 to ethernet converter? want to reach some board's ttyS0 via network |
| 17:40.28 | furan | you could build a telnet server with an ethernet-abled arduino |
| 17:41.44 | xxiao | http://www.saelig.com/product/ETH026.htm |
| 17:42.07 | jelly-home | I remember funky escape sequences needed to send Break over Sun's ALOM over telnet |
| 17:42.29 | rm | nice |
| 17:42.31 | xxiao | need a ttl3.3v for most boards on the rs323 side, that should be fine though |
| 17:43.23 | Turl | xxiao: I saw a bluetooth to uart thingy if of any use |
| 17:45.19 | xxiao | Turl: will BT work for 20 ft? |
| 17:45.26 | xxiao | only used BT earphone |
| 17:46.53 | xxiao | some boards are so noise it hurts my ears, i need put them farther with an ethernet gateway, not sure how long RS232 can go though |
| 17:46.58 | Turl | xxiao: idk, I'm not familiar with "ft" :P |
| 17:47.02 | xxiao | maybe should just get an extended rs323 cable |
| 17:48.43 | Turl | xxiao: https://www.dealextreme.com/p/wireless-bluetooth-rs232-ttl-transceiver-module-80711 |
| 17:50.49 | xxiao | Turl: cool |
| 18:06.35 | hno | xxiao, get a cheap ARM with Ethernet. |
| 18:09.50 | jelly-home | noone's trafficking cheap enough ARMs with ethernets here to .hr, so I decided to go with MK802 and http://dx.com/p/usb-2-0-3-port-hub-with-rj45-ethernet-network-lan-adapter-20cm-cable-51436 |
| 18:11.14 | hno | xxiao, there is also USB extenders/repeaters. With those you can go 150ft. |
| 18:14.52 | hno | usb1.1 only, but quite sufficient for console |

| 18:18.09 | hno | furan, eMMC been around for a while. For example N900 is using one for internal storage, but most of the OS in some other flash. |
| 18:18.11 | Turl | I connected two long usb cables |
| 18:18.16 | Turl | for like 4 metres total |
| 18:18.21 | Turl | passive cables btw |
| 18:19.14 | hno | up to 4-5 metres is ok without repeater. |
| 18:19.31 | Turl | hno: all relatively recent phones use eMMC for OS+data |
| 18:19.39 | hno | Turl, I know. |
| 18:20.55 | hno | using bare NAND isn't cost/space effective in phones. |
| 18:22.20 | Turl | samsung's got a firmware bug on some series that renders them unusable when you erase stuff |
| 18:22.53 | hno | nice |
| 18:24.17 | hno | can the firmware be upgraded? |
| 18:24.56 | Turl | not sure, but I don't think so |
| 18:25.15 | Turl | I think you can hex patch it while running however |
| 18:25.20 | hno | it would kind of make sense if a device with that amount of NAND had the firmware in NAND.. |
| 18:25.28 | Turl | in any case, you need to be samsung to fix it :) |
| 18:36.54 | rm | god, DX is turning into RadioShack |
| 18:36.58 | rm | and that's good |

| 21:49.19 | Turl | https://github.com/blog/1229-scheduled-maintenance-wednesday-22-00-pdt |
| 21:49.22 | Turl | was two days ago :P |
| 21:49.59 | hno | There, pushed a little experimental gem to u-boot repository. Now to give it a try... |
| 21:52.26 | Turl | * if we don't reset the gps module, it will access sdram * but sdram is not ready, and the system will die... |
| 21:52.40 | Turl | interesting comments on the code |
| 21:53.03 | WarheadsSE | heheh |
| 21:54.02 | Turl | why does gps need to poke sdram though? |
| 21:57.39 | WarheadsSE | good question |
| 22:02.06 | Turl | chinese GPS :P |
| 22:03.26 | *** join/#arm-netbook orly_owl (~david@unaffiliated/orly-owl/x-3167833) |
| 22:03.27 | WarheadsSE | and apparetly it stores stuff in sdram? le fuq |
| 22:13.32 | hno | Gah.. complete silence from sun5i SPL. |
| 22:14.30 | hno | Turl, we know very little about the GPS module. But I assume it has a CPU and needs to access code & data somewhere. |
| 22:14.34 | RaYmAn | and it's mostly impossible to jtag debug it without ability to load from nand, lol (well, not impossible I guess) |
| 22:14.57 | hno | RaYmAn, SPL? |
| 22:15.09 | RaYmAn | yeah |
| 22:15.30 | hno | That's why we have the jtag_loop hack. |
| 22:15.58 | RaYmAn | well, i guess if you leave out the sd loading part, it's not impossible. Without that it seems to disable jtag@sd |
| 22:20.01 | RaYmAn | I'm rambling, but yeah :P You just can't jtag debug the part that loads u-boot :) |
| 22:41.58 | hno | RaYmAn, yes. But there is many other ways to load. |
| 22:45.09 | hno | RaYmAn, target remote localhost:3333 |
| 22:45.11 | hno | monitor halt |
| 22:45.22 | hno | file spl/u-boot-spl |
| 22:45.26 | hno | load spl/u-boot-spl |
| 22:45.30 | hno | set $pc = 0 |
| 22:45.34 | hno | break reset |
| 22:45.37 | hno | continue |
| 22:49.24 | RaYmAn | yeah, I got that bit. |
| 22:49.40 | RaYmAn | doing that just runs through until it disconnects you from jtag - at least here |
| 22:51.33 | hno | mine hangs earlier.. |
| 22:52.05 | hno | and you can disable MMC support in the config. |
| 22:52.39 | hno | but it should not disconnect you from JTAG. u-boot-mmc do not touch PF GPIO settings. |
| 22:53.33 | RaYmAn | hm, interesting |
| 22:53.46 | RaYmAn | it might be the clock changes then |
| 22:57.03 | hno | Seems DRAM controller is not clocked or something. Hangs in dram_wait_init() |
| 23:01.54 | RaYmAn | got a dump of the boot0 for your device? |
| 23:02.10 | hno | RaYmAn, yes. |
| 23:02.39 | hno | same as yours I thinik, except for NAND storage parameters. |
| 23:09.40 | hno | RaYmAn, Allwinner-Info/A13/boot/... |
| 23:10.40 | RaYmAn | 'k |
| 23:11.27 | hno | and sun5i branch in uboot. |
