| 11:54.54 | coolhp | Good morning all. |
| 11:59.02 | coolhp | Do you need a particular "firmware" or revision of the MK802 in order for u-boot to work ? If I dump one of the old lubuntu images from back in june, I can get it to boot up. But when I try the u-boot approach rhombus-tech.net, I cant tell if something is happening or not. |
| 11:59.49 | mnemoc | not sure if it's your case or not, bu 1GB devices are not yet functional from open sources |
| 12:00.17 | coolhp | Ah ! |
| 12:00.27 | coolhp | That's the ticket ! |
| 12:00.51 | coolhp | Is there any workaround ? |
| 12:01.56 | mnemoc | i think I saw once some patches to let u-boot initialize the whole thing |
| 12:02.28 | mnemoc | the best way is to send a 1GB device to hno as gift :) |
| 12:02.56 | coolhp | :-) |

| 12:04.02 | mnemoc | the nand bootloader chain + linux built with the ignore atag_mem flag enabled should work |
| 12:04.37 | mnemoc | or the nand bootloader chain + two mem= arguments to the kernel |
| 12:05.19 | mnemoc | mem=448M@0x40000000 mem=512M@x60000000 should work IF the memory is alreaday initialized |
| 12:07.00 | coolhp | Ah. So am I understanding that the u-boot method "should" work as long as I set my boot.scr right ? |
| 12:07.10 | rm | mnemoc, not true |
| 12:07.26 | rm | they are functional with 512MB of RAM |
| 12:07.55 | rm | coolhp, I believe the current u-boot is somewhat broken |
| 12:08.27 | rm | also someone else mentioned old images working, but current nightlies not |
| 12:08.44 | mnemoc | rm: :) |
| 12:08.52 | rm | I suggest that you combine the SPL+uboot+boot partition from the old images, |
| 12:08.58 | rm | with your own root partition |
| 12:09.47 | coolhp | That's what I was trying to do in the beginning. In fact, the old Lubuntu image would work fine for my purposes if only I could find a way to recompile the kernel with a couple of additional modules.... |
| 12:10.07 | coolhp | But for some reason, I cant build a uImage that works. |
| 12:10.27 | coolhp | Mine is always 2Mb smaller than the one off of the image for some reason. |
| 12:10.28 | rm | which modules |
| 12:10.55 | coolhp | I'd need v4l support, g_serial and snd_usb_audio :-) |
| 12:11.02 | rm | I see |
| 12:11.22 | rm | I don't remember if my kernels enable these, probably not |
| 12:11.27 | specing | I don't think g_serial works |

| 12:11.35 | specing | it didn't last time I tried |
| 12:11.39 | rm | and some misc. stuff |
| 12:11.54 | specing | there is a /dev/ttyGS0 but ... nothing in lsusb |
| 12:13.37 | coolhp | g_serial is sort of optional for what I have in mind :-D... Basic electronics question : If I wire the UART port on the side of the MK802 to a serial port (GND to GND and MK802-TX to Serial-RX), would that allow me to see some of the boot process logs ? |
| 12:13.58 | specing | coolhp: you need a 3.3V converter |
| 12:14.27 | coolhp | Damn.... |
| 12:15.14 | coolhp | Not much I can do withouth that I guess ? |
| 12:15.51 | specing | no |
| 12:16.25 | specing | Unless you get a usb-serial dongle without a line driver |
| 12:16.53 | coolhp | I've got a run of the mill PL-2303.... |
| 12:17.20 | specing | if you are unsure get a voltmeter |
| 12:17.43 | specing | if its tx line is at 3v3 when it is not transmitting, it is safe |
| 12:18.04 | coolhp | Checking :-) |
| 12:19.08 | RaYmAn | if you're only connecting GND and TX from mk802 to pl2303 GND and RX, then you can't really break anything by just trying it out :) |
| 12:20.02 | specing | what if you get it wrong? :P |
| 12:20.07 | specing | (happens) |
| 12:21.35 | specing | its better to spend 5 minutes making sure it is what you want it to be than frying the only debug option |
| 12:22.53 | RaYmAn | as long as you connect TX(mk802) only, at most you could fry the pl2303 - but mk802 outputs 3.3v, so even if the pl2303 is setup for 5v, it'd just not get any data |
| 12:23.25 | RaYmAn | If you connect RX (mk802), and the pl2303 outputs 5v or more, it could potentially fry the output |
| 12:23.53 | mnemoc | my pl2303 works at 3.3V... |
| 12:23.55 | RaYmAn | but as long as you are only connecting to RX on pl2303, it only "listens" for voltage, so pretty hard to break |
| 12:24.19 | RaYmAn | mnemoc: it varies - I have one where you have to switch a jumper between 3.3v and 5v depending on usage |
| 12:24.38 | RaYmAn | mind you, it'd probably still detect 3.3v signals just fine |
| 12:25.29 | coolhp | 115200, N 8 1 ? |
| 12:26.06 | RaYmAn | go for it :> if those settings are wrong, you either get nothing or garbage |

| 18:59.42 | coolhp | and pin 2 on UART TX |
| 19:01.16 | Turl | coolhp: can't you use this gnd? http://linux-sunxi.org/File:Mk802_uart.jpg |
| 19:01.27 | Turl | it's confirmed working, so you can discard it's that if it doesn't work still |
| 19:01.50 | mnemoc | coolhp: you need somehting like http://www.ebay.com/itm/New-PL2303-USB-To-RS232-TTL-Converter-Adapter-Module-/130682850512 |
| 19:02.34 | coolhp | Yup... seen those around. I'm just an impatient little bastard and dont want to wait for one to get here *grin* |
| 19:03.03 | RaYmAn | may as well order a couple while you're at it :P They are surprisingly useful to have around :) |
| 19:03.04 | mnemoc | coolhp: buy it from your country |
| 19:04.28 | coolhp | The funny thing is : I've got a couple of BC547 transistors around... if only I could find a proper +5V source on my USB side, I would simply pull the signal up |
| 19:04.59 | Turl | mnemoc: they charge like 25USD for the 2303 ones over here lol |
| 19:05.13 | mnemoc | :D |
| 19:05.47 | RaYmAn | and you can get them from like 2$ from china, lol..Including shipping |
| 19:05.50 | RaYmAn | that just seems insane :P |
| 19:06.03 | mnemoc | yeah |
| 19:06.15 | RaYmAn | finally decided to order JTAG thingymabob |
| 19:08.26 | mnemoc | has a flyswatter |
| 19:08.31 | Turl | yeah, I'm thinking of ordering maybe 10 and reselling for cheaper :P |
| 19:08.45 | RaYmAn | lol |
| 19:09.04 | RaYmAn | mnemoc: cool! what are you using it for? I went for a Bus Blaster v2 cause it's cheapo and same hardware as flyswatter |
| 19:09.18 | mnemoc | RaYmAn: collecting dust :p |
| 19:09.22 | RaYmAn | lol |
| 19:09.33 | RaYmAn | I'm sure that's what my bus blaster will end up doing as well |
| 19:09.33 | RaYmAn | :P |
| 19:09.34 | mnemoc | as i can't solder... |
| 19:09.42 | RaYmAn | ^^ |
| 19:09.59 | RaYmAn | Just need devices where JTAG is on a header :D |
| 19:10.12 | mnemoc | exactly :p |
| 19:10.36 | RaYmAn | did you ever try it on any a10 devices? :) |
| 19:10.52 | RaYmAn | (you had one of those microsd breakouts, right?) |
| 19:11.01 | mnemoc | waiting for one with the pins exposed :) |
| 19:11.07 | RaYmAn | ah |
| 19:11.08 | mnemoc | yes, indeed |
| 19:11.12 | RaYmAn | I just got mine today |
| 19:11.19 | RaYmAn | with pins exposed and it mentions JTAG |
| 19:11.26 | mnemoc | nice |
| 19:12.06 | coolhp | Any of you have a 1G MK802 ? |
| 19:12.15 | WarheadsSE | coolhp: wait, are you using a PC serial to attep to get to the MK802? |
| 19:12.20 | mnemoc | coolhp: rm |
| 19:12.28 | RaYmAn | has too, but haven't tried serial |
| 19:12.36 | coolhp | WarheadsSE : Yes |
| 19:12.41 | WarheadsSE | .. 3.3v, yes? |
| 19:13.19 | coolhp | WarheadsSE : On the PC end, nope :-( ... Its just RS232 |
| 19:13.51 | coolhp | RM : Do you have it running some linux distro ? |
| 19:14.38 | WarheadsSE | These devices are ALL 3.3v rs232/ttl |
| 19:15.39 | coolhp | Which ones ? |
| 19:15.40 | RaYmAn | WarheadsSE: he only connected TX from device + it was connected to an DB9 port on a pl2303 based usb adapter - so probably no harm (just bringing you up to speed ;)) |
| 19:15.55 | RaYmAn | allwinner devices, tegra devices, omap devices, etc :) |
| 19:16.04 | WarheadsSE | Yeah, if he was only listening yes |
| 19:16.18 | WarheadsSE | almost all embeded arms are native 3.3v rs232/ttl |
| 19:16.56 | WarheadsSE | there are PL2303's out there @ 5v |
| 19:17.07 | WarheadsSE | but without ground attached, it will always be gibberish |
| 19:17.32 | RaYmAn | read what he wrote :P |
| 19:18.30 | WarheadsSE | I did |
| 19:18.41 | WarheadsSE | just saying, its gonna be complete jibberish til he gets a proper ttl |
| 19:19.59 | RaYmAn | if it is pl2303 based there was a chance it would be able to handle the 3.3v signals as well though (at least receiving from device) |
| 19:20.02 | RaYmAn | :) |
| 19:20.16 | WarheadsSE | Theoretically, yeah |
| 19:20.30 | coolhp | RaYmAn : Do you have your MK802 running something off of an SD card using u-boot ? |
| 19:20.31 | WarheadsSE | thats the problem though ;) "theory" |
| 19:20.48 | WarheadsSE | hasn't received his MK802s yet |
| 19:21.14 | RaYmAn | coolhp: yeah - I've at least tried it with an ubuntu image |
| 19:21.17 | thefrog | specing: yes.. it was the phorocrap. lots of warning that nothing would come of it. |
| 19:22.17 | coolhp | *sigh*... I must be doing something wrong... but until I can get some sort of display to see what's going on, i'm screwed. |
| 19:22.49 | RaYmAn | coolhp: what image are you trying? |
| 19:22.54 | mnemoc | coolhp: start by ordering the right ttl/usb adapter |
| 19:23.19 | WarheadsSE | FTDI are expensive, but reliable |
| 19:23.30 | RaYmAn | coolhp: you could try this version of ubuntu: https://www.miniand.com/forums/forums/2/topics/1 |
| 19:23.44 | rz2k | [23:23:20] <WarheadsSE> FTDI are expensive, but reliable - I have two died last month. |
| 19:24.28 | RaYmAn | hmm..that's actually not bad https://www.miniand.com/products/Hackberry%20A10%20Developer%20Board - 65$ |
| 19:25.10 | coolhp | Rayman : I've actually got those images running !... that's the worst part... those images use the old bootloader... with the evb.bin file. It actually works like a charm. |
| 19:25.28 | coolhp | The issue is : I need to build a custom kernel for some extra modules. |
| 19:25.54 | RaYmAn | you need to disable at least cpufreq and some power management stuff to get it booting afaik |
| 19:26.00 | RaYmAn | pokes IEF |
| 19:26.07 | coolhp | And when I try to build a new kernel, My uImage always comes out smaller. |
| 19:26.12 | mnemoc | meh, the 1GB model is out of stock :< |
| 19:26.26 | coolhp | mnemoc : Where are you ordering from ? |
| 19:26.54 | RaYmAn | mnemoc: you really need more a10 deviceS? :P |
| 19:27.02 | rz2k | so now we have three a10/13 devboards. |
| 19:27.23 | mnemoc | RaYmAn: nah, just want one with 1GB _and_ uart pins |
| 19:27.42 | RaYmAn | ah |
| 19:27.49 | WarheadsSE | coolhp: are you compressing the image before placing it in uImage? |
| 19:28.13 | mnemoc | rz2k: competition is good :) |
| 19:28.34 | WarheadsSE | I'll have to see if olinuxo will send ALARM some of the A13's |
| 19:28.38 | rz2k | mnemoc: still only eoma68 will give you all free IOs |
| 19:29.09 | mnemoc | rz2k: ? |
| 19:29.57 | mnemoc | rz2k: afaik the olinuxino and the cubieboard will expose all free pins too |
| 19:30.15 | rz2k | I didnt know that |
| 19:30.20 | coolhp | Warheads : could be, could be... I'm doing make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j3 uImage |
| 19:30.34 | rz2k | thought olinuxino is just SBC and no news about cubieboard |
| 19:30.49 | mnemoc | rz2k: AND an eoma68 card with expansion header stops been an eoma68 card |
| 19:31.25 | coolhp | mnemoc : I ended up getting some of those too : http://www.aliexpress.com/product-gs/581048462-1080P-2160P-HD-Google-TV-player-AK802-Android-4-0-512MB-1GB-free-shipping-wholesalers.html |
| 19:32.05 | coolhp | In fact : Here -> http://www.aliexpress.com/product-fm/576584621-Android-4-0-Mini-PC-IPTV-Google-Internet-TV-Smart-Android-Box-1GB-RAM-4GB-ROM-wholesalers.html |
| 19:32.06 | mnemoc | coolhp: I have zero use for that kind of device |
| 19:32.27 | WarheadsSE | well the resulting uImage should be able to tell you if the contained kernel is compressed or not |
| 19:32.27 | mnemoc | rz2k: http://olimex.wordpress.com/2012/07/31/a13-olinuxino-first-prototypes-are-ready-for-testing/ |
| 19:32.45 | mnemoc | rz2k: and the cubieboard has 2x48 pin headers |
| 19:32.57 | coolhp | Oh... sorry menmoc.. I Thought you were looking for some... your comment about out of stock. |
| 19:32.58 | rz2k | I didnt get any cubieboard news so far.. |
| 19:33.20 | mnemoc | coolhp: I want a development board |
| 19:33.40 | mnemoc | rz2k: I saw some pictures of the prototype.... looks NICE |
| 19:34.20 | rz2k | I saw only one picture of board layers without GND fill |
| 19:35.03 | coolhp | mnemoc : gotcha.. sorry. The hackberry would be pretty cool in that case. I use the MK802s as development boards but that's just because I dont necessarily need GPIO... the only interractions I'm going to have with external HW is via USB |
| 19:35.07 | RaYmAn | It's cool so many fairly cheap dev boards are coming out |
| 19:35.17 | mnemoc | yeah |
| 19:35.38 | RaYmAn | with the ouya console coming it at 99$, it should theoretically be possible to get a cheap tegra3 dev board as well (and with the mali400 quad board as well!) |
| 19:36.12 | coolhp | I really want to see some dev boards with Intel Medfield on it. |
| 19:36.35 | coolhp | I'd be really curious to see how it pairs up against the ARM solutions out there |

| 20:04.48 | RaYmAn | It feels like a funky choice that the pins that are by default configured as JTAG are the same as sd controller0 |
| 20:04.58 | RaYmAn | but I guess it does make it easy to do it on production devices |

| 20:07.37 | rz2k | I've already tried to find something at ly-f1 testpoints |

| 20:08.16 | MrChrisDruif | A10 tablet? |
| 20:08.25 | MrChrisDruif | I've been looking at one myself |
| 20:08.26 | RaYmAn | well, from what I understand, it's usually shared with microsd port (e.g. before bootloader touches config, the microsd pins are configured for jtag) |
| 20:08.27 | rz2k | http://linux-sunxi.org/File:LY-F1_pcb_back.jpg |
| 20:08.36 | rz2k | here is pic, I've marked what I've figured out |
| 20:09.07 | RaYmAn | that's cool |
| 20:09.17 | RaYmAn | I should really try taking apart my a13 tabs, heh |
| 20:09.39 | mnemoc | yes |
| 20:09.49 | rz2k | I believe a13 tabs made by same manufacturer |
| 20:10.01 | rz2k | so they will have same testpoints management :p |
| 20:10.55 | RaYmAn | I suck at soldering so stuff over sdcard is easiest ;P |
| 20:12.02 | mnemoc | RaYmAn: but the wiki wants pictures, specs, and fancy info about your tabs even if you wan't solder anything... |
| 20:12.11 | RaYmAn | lol |
| 20:12.14 | RaYmAn | yaya :P |
| 20:12.19 | RaYmAn | It's on my list |
| 20:12.22 | rz2k | nah, thats pretty big testpoints. on my Renesas EV2 tablet UART is located at flat-flex cable connector with absolutely crazy pitch |
| 20:13.35 | RaYmAn | did you try the sd testpoints for jtag? |
| 20:14.31 | mnemoc | cheap SoC -> cheap factory -> almost everything done by human labour |
| 20:14.46 | mnemoc | -> big test pads |
| 20:15.05 | rz2k | nope, gave up on testpoints around processor |
| 20:15.14 | rz2k | but I've found a good testpoint for VCore |
| 20:15.23 | RaYmAn | rz2k: well, I'm fairly certain it's on SD :P |
| 20:15.40 | rz2k | I will check it out as soon as I will bring j-link to home |
| 20:16.13 | MrChrisDruif | SATA support has been removed as far as I can tell from A13 compared to A10 |
| 20:16.39 | RaYmAn | coolhp: try this defconfig http://skumler.net/mk802config (courtesy of IEF, not me :P) |
| 20:16.50 | RaYmAn | MrChrisDruif: and HDMI |
| 20:17.48 | MrChrisDruif | So if those are the drawbacks to A13 to A10 it's not so much. I don't know what the price differences between similar tablets will be |
| 20:17.53 | RaYmAn | anyways, bedtime. later *hopes for speedy DHL shipment so he can get jtag thingymabob tomorrow* |
| 20:17.54 | rz2k | I think a13 has many things stripped off to make it to TQFP package. maybe it even is same CPU die but with different fanout |
| 20:18.03 | MrChrisDruif | Sleep well RaYmAn |
