#136 veyron speedy uboot fails to boot

Open
opened 4 weeks ago by gdallasdye · 0 comments

So I built a veyron speedy uboot payload rom for my C201 the other day, and it shows no indication of booting. I can see a black screen and a flash of white line. I don't think linux is booting because I can't ssh into it and I don't have a UART debugger or pads apparently. I'm also not sure if uboot is crashing or if coreboot crashed before that. Good thing I have an external flasher.

So has anyone else had success in flashing libreboot+uboot to veyron-speedy? Any failures? Anyone have their backups at hand? What about veyron boards? What I'm looking for are volunteers who would be willing to backup their factory roms and post their fmap dumps. Then we can look at commonalities and differences.

The flashmap utility is now a part of futility, and can be installed with sudo apt install vboot-utils. From there we can run futility dump_fmap /path/to/c201.rom

This is the dump from what I built: https://paste.debian.net/1265625/

This is the dump from my factory image: https://paste.debian.net/1265626/

For what it's worth, my C201 has 4GB of ram and a usqwerty keyboard, intended for North American consumers. It's an AZUREWAVE/AW-CM195F C201PA-DS02 manufactured 2017-03.

EDIT: I've done another build, this time with alpernebbi's PR: https://notabug.org/libreboot/lbmk/pulls/137

I've also built for both C201PA and C101P. I'm not seeing an elf file in the veyron board.

Also about the missing uboot warning... Is that a fake warning or a real warning?
