Re: [coreboot] vga & serial debug support when building grub2 as payload
by John Lewis 25 Sep '13

I think that's the same vendor ID as the Pixel, so perhaps the Pixel VGA bios in "snm_2137.dat" in "3rdparty/mainboard/google/link" will work?

Hello Paul, David, I have the same problem with VGA, I am looking into my coreboot settings: CONFIG_VGA_ROM_RUN=y CONFIG_VGA_BIOS=y CONFIG_VGA_BIOS_ID="8086,0166" CONFIG_VGA_BIOS_FILE="./src/vbios.bin" I do not see any of: vbios.bin or vgabios.bin in directory src/ I am using Cougar Canyon 2 or equivalent which is Emerald Lake 2. What PCIe VGA should I use (I think I know how to discover this one)? How I can get vbios.bin for these boards (I assume the vbios.bin) is the same for both of them? Thank you, Zoran _______ Most of The Time you should be "intel inside" to be capable to think "out of the box".

What board do you use? If coreboot successfully runs the VGA BIOS/Option ROM (and if it is needed), GRUB 2 should be able to display text on the monitor. I am successfully doing that on the ASRock E350M1. Do you get graphics with SeaBIOS as a payload and letting SeaBIOS run the VGA BIOS/Option ROM? > (2)How can I enable serial prot debug after Grub2 Payload is loaded? > I have add the following to grub.cfg and use "grub-mkimage -c ./grub.cfg ......." to make the Grub2.elf. > serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1 > terminal_input --append serial > terminal_output --append serial > > But it doesn't work after grub2 payload is called! That should work. Do you get serial output with coreboot? Do you get serial output from the GRUB installed on your hard disk? Does TankTang also need to set GRUB_GFXMODE (ie GRUB_GFXMODE=640x480) in grub.cfg?

Actually, regretfully, I am afraid I added to some confusion here. As it happens the chromebooks may be the best way to go for this. With the enhancements Nico created, it's not possible to install a coreboot that 'wraps around' the already installed mrc.bin and me binaries. So you don't need those files on a chromebook -- they're already there. YMMV with other systems. This is all still pretty experimental (read: I have no clue if it works, not having tried it) but it's supposed to work.Would love to hear that it does. ron

Hi Zoran, my intention was just to do some experiements with coreboot - and haswell was the most interessting platform for me. looks like i have to wait until intel allows release of mrc.bin or use some other platform.

vga & serial debug support when building grub2 as payload
by jstkf2012＠126.com 23 Sep '13

23 Sep '13

Hi Maillist, I am a bios engineer from Byosoft. Unfortunately, I meet 2 questions about building Grub2 as coreboot's payload. (1)How can I enable vga support during post? I have configure the following token: CONFIG_VGA_ROM_RUN=y CONFIG_VGA_BIOS=y CONFIG_VGA_BIOS_ID="8086,0166" CONFIG_VGA_BIOS_FILE="./src/vbios.bin" But it seems that it doesn't make sence.Is there something need I to do in Grub2 to support vga. (2)How can I enable serial prot debug after Grub2 Payload is loaded? I have add the following to grub.cfg and use "grub-mkimage -c ./grub.cfg ......." to make the Grub2.elf. serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1 terminal_input --append serial terminal_output --append serial But it doesn't work after grub2 payload is called! I need your great help! Thanks, TankTang jstkf2012(a)126.com

Fwd: crossgcc build fails
by Marcello Stanisci 22 Sep '13

22 Sep '13

Yes, this patch fixed it. The compilation process ends with no complaints. Now, I just want to build coreboot+coreinfo for Qemu but, following the howto in [1] (and in [2]) I can't really figure out how to call the cross compiler for a desired architecture. How do you do it?
