This is clearly totally unrelated to SeaBIOS, and it looks like an
linux/grub installation problem.

If you see nothing after that, then that probably means that SeaBIOS
executed whatever was on the drive's boot sector and that failed to do
anything, so grub crashed or there was no grub in the first place, or
it was misconfigured and it stopped instead of showing some error
message, etc.. whatever the issue is, it looks like it's not related
to SeaBIOS.

What OS is that ? What's the error of update-initramfs ? Did you try
to run update-initramfs manually to see what error it gives you ? I
remember seeing a similar error related to a busybox depedency (this
error https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=864143) and I
can't remember the exact fix, but it was something like : edit
/etc/initramfs-tools/initramfs.conf and change the "BUSYBOX=auto" to
either "y" or "n", one of them fixes it. Or maybe it was the file
/usr/share/initramfs-tools/conf-hooks.d/cryptsetup, or maybe you have
to add a line "BUSYBOXDIR=/bin" to the config..
Either way, you should fix whatever is causing that first.

Yeah, upgrading coreboot won't change anything if your hard drive
doesn't have a working grub installed on it.
I think your issue here might be that "update-grub2" will update the
grub files in /boot (from the live USB), not in /mnt/root/boot. I
would suggest to simplify your life and just "mount /dev/sda1 /boot"
so the update would work (even if you manually use grub-mkconfig -o
/mnt/root/boot, it will still scan some things in /boot, and it might
mess things up, so just mount it on top of the existing /boot and call
update-grub)

I haven't heard of this issue, usually, if it's related to coreboot, I
get asked for my opinion, but I suppose I wasn't poked about it by
tech support because it's a linux/install problem, and indeed, it's
not related to coreboot.

As for all that stuff about getting seabios debug, I don't know how
much that will help you. I'm sure all you'll see is something like
"jumping into boot sector" then nothing, it's not like the cbmem
console log will have the grub debug output in it saying "I'm about to
crash because I can't find my config" for example. Unless SeaBIOS sets
up a segfault handler or something prior to jumping into boot drive
and writes to the log a crash report, I have no idea if it does that.

I hope that helps, good luck. And if you need more help, I suggest not
to spam this mailing list with non-seabios-development related
questions, you can continue emailing me directly.

Dear Philip,


First of all, please respect the netiquette and do not top post. It 
makes replying much harder. Please use the interleaved style in the future.

Second, I really think this not a SeaBIOS issue, but a hard drive issue. 
But it seems functional, as SeaBIOS is listing it in the boot menu, and 
you can access it from the live installation.

1.  You need to capture the coreboot and SeaBIOS messages. Does the 
device have ports which can be used for debugging? As it’s a laptop, 
that is probably not the case.


You could see if the messages are preserved during reboot. So, plug in 
the device with the live distribution, try to boot from the drive, get 
the error, and (warm) reboot, and select the distribution. Build 
`cbmem`, by getting the coreboot source code [1], and then do `make -C 
util/cbmem`. Or start a Linux kernel with 
`CONFIG_GOOGLE_MEMCONSOLE_COREBOOT` and look into `/sys/firmware/log`.


2.  See if the option *SPI Flash console output* 
(`CONFIG_CONSOLE_SPI_FLASH`) is supported on your board. The Puri.sm 
folks should know and help you with that.



Send coreboot debug output to the SPI Flash in the FMAP CONSOLE area

This option can cause premature wear on the SPI flash and should not
be used as a normal means of debugging. It is only to be enabled and
used when porting a new motherboard which has no other console
available (no UART, no POST, no cbmem access(non bootable)). Since
a non bootable machine will require the use of an external SPI Flash
programmer, the developer can grab the console log at the same time.

The flash console will not be erased on reboot, so once it is full,
the flashconsole driver will stop writing to it. This is to avoid
wear on the flash, and to avoid erasing sectors (which may freeze
the SPI controller on skylake).

The 'CONSOLE' area can be extracted from the FMAP with :
cbfstool rom.bin read -r CONSOLE -f console.log



Kind regards,

Paul

[SeaBIOS] Librem 15v3 hangs at Booting from Hard Disk...

[Philip C.]

Hello everyone!

I've been having some issues with a laptop recently. My Librem 15v3 was
bouncing along, until one day I ran into an apt-get upgrade issue. I
attempted to fix the affected script by pointing it to the base directory
busybox lived. The upgrade completed without any apparent issue.

But, now no matter what I do, unattended boots hang on

SeaBIOS (version rel-1.11.0-0-g63451fc)
Booting from Hard Disk...
_

I have tried reinstalling the OS, using their live boot ISO. Each time, no
matter which disk I configure (/dev/sda or /dev/nvme0n1), the install fails
with the message

Installation failed Failed to run update-initramfs on the target The exit
code was 2

I have upgraded coreboot, no joy. I have also tried manually running grub,
from the installer, ie


   1. mkdir /mnt/root
   2. cryptsetup luksOpen /dev/sda3 root
   3. mount /dev/mapper/root /mnt/root
   4. mount /dev/sda1 /mnt/root/boot
   5. grub-install --boot-directory=/mnt/root/boot /dev/sda
   6. update-grub2

The folks at purism/librem seem to be as confused as I am. Does anyone here
have any insight into how I can fix this problem?

Thanks!
