| 06:54.05 | hno | cubieboard have 2 USB HOST + 1 OTG. |
| 06:55.23 | rzk | hey hno, is there any chance to boot something on A13 from mmc right now using uboot-allwinner sun5i branch? |
| 06:56.01 | hno | rzk, Well, u-boot boots fine. Not sure if it's capable of also booting a kernel.. |
| 06:58.14 | rzk | also, if my device doesnt have reset button, am I stuck with "#error reset the board#" on cold boot? |
| 06:59.18 | rzk | I remember sometime ago you managed to reset the board remotely for some reason |
| 07:01.25 | hno | rzk, cold boot should work fins. |
| 07:01.29 | hno | s/fins/fine/ |
| 07:01.47 | rzk | on my A10 tablet it never did with u-boot from mmc. |
| 07:02.31 | hno | did you try another SD card? It's apparently a bit picky on the type of card used. |
| 07:02.59 | hno | probably some little detail missing in the u-boot mmc setup. |
| 07:04.09 | hno | (un)fortunately cold boot works with all cards I have. |
| 07:04.49 | rzk | yep, but nevermind, that A10 tablet is dead anyway, bad BGA job by manufacturer and my laziness to reflow it right way. |
| 07:06.07 | hno | my remote reset is just that I managed to wire my JTAG adapter on the A13 board so that I can reset the board, and also figured out how to tristate the other lines so it does not disturb SD booting. |
| 07:06.22 | rzk | cool, what jtag do you use? |
| 07:06.30 | rzk | generic ft2232? |
| 07:06.43 | hno | An olimex one, FT2232 based. |
| 07:06.59 | hno | ARM-USB-TINY-H |
| 07:07.35 | rzk | at JTAG article at wiki there is a adapter board with some pull-up/downs, are they mandatory? |
| 07:07.54 | rzk | or that is inline 10-20ohms? |
| 07:09.02 | hno | Works fine without them for me. But there is both inline resistors and pull downs (or was it up, don't remember) on the A13 board. |
| 07:09.32 | hno | I have both SD-card and JTAG connected in parallell. |
| 07:10.41 | rzk | now its time to find out what is what in this heap of testpoints http://linux-sunxi.org/File:Q88-pcb2.jpeg |
| 07:17.25 | hno | Looks like mostly touch panel stuff. |
| 07:17.52 | hno | but one of the big one is labelled RST, might be system reset. |
| 07:21.23 | hno | Ah, the rest there is the SD UART pins. |
| 07:21.44 | hno | but if you plan on SD booting then finding UART1 pins (PG3/PG3) helps a lot. |
| 07:23.03 | hno | PG3/PG4 |
| 07:25.10 | rzk | thanks hno |
| 07:49.35 | hno | rzk, UART1 is most likely the two pads between the SD slöt and A13. |

| 21:04.00 | L84Supper | are there any real time / fast IRQ's on the GPIO of the cubieboards? |
| 21:04.26 | Turl | L84Supper: you'll have to ask hipboi |
| 21:04.45 | L84Supper | when is Tom around? |
| 21:04.59 | L84Supper | 05:00 there now |
| 21:05.09 | L84Supper | maybe in a few hours |
| 21:05.20 | Turl | yeah |
| 21:05.33 | Turl | https://www.google.com/search?q=time+in+shenzhen <- helps :D |
| 21:07.22 | L84Supper | has he posted the 96 pin header pinout somewhere? |
| 21:08.22 | Turl | no idea |
| 21:08.30 | Turl | heh board has sata 5v port even http://cubieboard.org/wp-content/uploads/2012/09/cubieboard_top.jpg |
| 21:08.46 | L84Supper | I just have the incomplete data sheet and some reference schematics for the A10 |
| 21:08.54 | rm | requiring some bizzare plug |
| 21:09.27 | Turl | rm: http://cubieboard.org/wp-content/uploads/2012/09/cubieboard_back1.jpg |
| 21:09.34 | L84Supper | that plug should be easy |
| 21:09.37 | Turl | looks like jumper cable-able, or shieldish style |
| 21:11.04 | L84Supper | not much current capacity on those two pins |
| 21:11.26 | rm | <L84Supper> are there any real time / fast IRQ's on the GPIO of the cubieboards? |
| 21:11.33 | rm | I'd ask are there any GPIO at all |
| 21:11.48 | rm | > "96 extend pin including i2c, spi, lcd, sensors, .." |
| 21:11.53 | rm | doesn't mention GPIO |
| 21:11.59 | hno | pinouts have not been posted yet I think. |
| 21:12.02 | L84Supper | maybe not |
| 21:12.03 | Turl | rm: all those crapton of pins are gpios multiplexed with all that I believe |
| 21:12.15 | L84Supper | yeah, lots of muxing |
| 21:12.21 | hno | yes, nearly all A10 I/O pins are GPIO capable. |
| 21:12.48 | L84Supper | i wonder how many GPIO are actually fast |
| 21:12.58 | hno | fast as in? |
| 21:14.05 | L84Supper | not just for LED's or switch inputs with debounce or similar but for <uS setup times |
| 21:14.32 | L84Supper | nS setup and hold times |
| 21:14.58 | hno | It's CPU controlled, which puts some limits on time ranges. |
| 21:16.13 | L84Supper | I've never seen any specs on the IRQ arbitration in the A10 or how the internal buses are even arranged |
| 21:16.14 | rzk | lol, all available A13 livesuit images that I've found have wrong image header, saying different file size than its really are |
| 21:16.36 | Turl | hmm |
| 21:16.37 | Turl | http://cubieboard.org/about/ |
| 21:16.41 | L84Supper | no AC timing specs |
| 21:16.43 | Turl | hipboi claiming 1.5Ghz |
| 21:16.53 | rzk | because of that, all unpackers for livesuit images fail miserably, allocating not enough memory for the file. |
| 21:20.11 | hno | calls it a night. Smells like something is wrong with a clock somewhere. |
| 21:22.18 | Marex | hno: night! |

| 21:25.08 | hno | It's really strange. Everything seems perfect fine until the Linux banner printk. There I can't even step into the function. Instead the board crashes and not even JTAG can talk with it. |
| 21:26.54 | rzk | early_printk is allwinnerized, no? |
| 21:27.11 | hno | This is a real printk. |
| 21:27.46 | hno | but I can't even step into the beginning of printk, trying to step into the function call crashes. |
| 21:30.56 | rzk | how I remember, before printk you have debug-macro.S executing. |

| 21:33.49 | rzk | yeah, I've found commit https://github.com/amery/linux-allwinner/commit/0a258e169eff26d733da71326944df40d2238852 |
| 21:34.53 | rzk | good luck with fixing that, I will try to boot kernel soon too on a13-mid. just found that I dont have any UART adapters around :/ |
