05:39 <narmstrong> Yardanico: did the binary work ?

14:55 <Yardanico> narmstrong: for some reason the tv box just didn't want to read u-boot from sd card, and I tried to flash that uboot directly to eMMC and bricked it a bit. Bought a USB A M-M cable today, and flashed some android firmware, will also connect UART (I have a spare nodemcu esp8266 which can be used for uart-wifi bridge)

14:56 <Yardanico> The reason I wanted to compile my own u-boot is to boot arch linux arm kernel (for some reason it just doesn't boot, although the armbian kernel does). So I'll try to boot it with stock u-boot and with uart to see why doesn't it want to boot arch kernel

14:59 <Yardanico> well maybe the u-boot from sd card actually worked but it just didn't fix my arch linux problem :D I'll check it when I get an UART running though

15:11 <narmstrong> Yardanico: you can chainload mainline uboot from the vendor uboot

15:11 <narmstrong> Yardanico: it works well and is much simpler

15:13 <narmstrong> `usb start;fatload usb 0 0x1000000 u-boot.bin;go 0x1000000` from usb for example

15:44 <Yardanico> narmstrong: thank you, I also got wifi-UART transparent bridge (https://github.com/NaoNaoMe/ESP8266-WiFi-UART-transparent-bridge) flashed on ESP8266, now I'm gonna figure out a good way to connect it to my TV box (that's not very hard though)

18:18 <Yardanico> well, I finally managed to capture vendor uboot, and it's "U-Boot 2015.01-gff1cbc0660-dirty (Apr 08 2018 - 09:35:05)", also "BL2 Built : 11:04:41, Jan 26 2018."

18:18 <Yardanico> just for info, gonna start actual linux stuff now

18:27 <Yardanico> btw, is q200 similar to q201? The u-boot log says it uses q201 3gb version for my tv box

18:29 <khilman> q201 only has internl PHY

18:30 <khilman> q200 has a choice between interal or external (gbit I think) phy

18:31 <khilman> basic DT for both are upstream: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/boot/dts/amlogic/

18:31 <Yardanico> khilman: oh, thanks :)

18:32 <Yardanico> btw, the funny thing is that I don't have a soldering iron right now so yes, I captured uart log by holding the wires to the board with my fingers), gonna boot from armbian just to check it works, and then will start with arch kernel

19:22 <Yardanico> so what can be the issue if the uboot successfully reads Image.gz of arch linux but after "Starting kernel ..." and "uboot time: 8413820 us" there's no output?

19:23 <Yardanico> well, I'm gonna try mainline u-boot anyway

19:30 <khilman> Yardanico: are you trying to boot mainline linux? If so, first thing to change is the serial console on the cmdline. Try `console=ttyAML0,115200`

19:30 <khilman> the vendor kernel uses ttyS0 which doesn't exist upstream, so you wont see any serial console output

19:31 <Yardanico> khilman: well when booting armbian I got all kernel output from uart

19:31 <Yardanico> idk if it's fully mainline though, maybe they have patches

19:31 <khilman> I don't know what kernel version armbian uses

19:32 <Yardanico> the latest armbian provided for my device uses 5.3.0-aml-g12

19:32 <Yardanico> so not mainline I guess

19:33 <Xogium> it is

19:33 <Yardanico> khilman: I think I might have had an error in my uEnv.ini, it was like "console=ttyAML0,115200n8 console=tty"

19:33 <khilman> that looks fine

19:34 <Yardanico> there's also other thing that bothers me - for some reason the s905_autoscript for armbian loades the armbian zImage kernel using "booti"

19:34 <Yardanico> s/loades/loads

19:53 <Yardanico> ugh, it seems I have the same issue as in https://archlinuxarm.org/forum/viewtopic.php?t=13172&p=59727

20:19 <Yardanico> narmstrong: I tried the chain loading and I get u-boot "bootloop" with it with "Synchronous Abort handler, esr 0x02000000" error: https://paste.debian.net/1104077/

20:22 <Yardanico> s905_autoscript.cmd: https://paste.debian.net/1104079/

20:23 <Yardanico> (ignore the dtb part, I tried to fix arch with it, but it does not have any effect on u-boot booting since that also happened without it)

20:31 <Yardanico> maybe it has some effect though - I used "aarch64-elf-" for cross-compilation instead of "aarch64-none-elf", is that maybe incorrect?

20:43 <Yardanico> built u-boot.bin binary from fip directory: https://filebin.net/3k3qczq96rn33pur/u-boot.bin

20:53 <Yardanico> printenv output (just in case): https://paste.debian.net/plain/1104090

21:26 <Yardanico> Ok, good night (my account will still be there because I use quassel so you can reply anytime)
