Blank Screen After Internally Flashing x230-hotp-verification

[lsafd]

First off I would like to say that I am a relatively new user so please excuse the mistakes that I will probably make.

I am flashing to a x230 and having similar issues to #667. I am using x230-hotp-verification as my final payload for the internal flashing. I have previously used x230 as my final payload and had success, so this is not my first installation.

Steps:

1. Flash x230-flash.rom image to the top chip.
2. Flash 8MB unlocked and me cleaned image to the bottom chip.
3. Boot to heads shell (So far everything is working)
4. Run mount-usb.
5. Run flash.sh -c /media/coreboot.rom to flash the 12MB coreboot.rom image (from ./build/x230-hotp-verification/).
6. Run reboot to reboot. (I have also tried rebooting using the power button.)

I end up with a blank screen, but the green light for the power button turns on and off as expected.

Attached is the coreboot.rom file. I have done a clean build and ended up with a coreboot.rom file that has the exact same sha256 hash.

Is there any information I could provide or new strategies I could try? I could post images of me running flash.sh if that would help. I am just unsure where to go from here. Any help would be much appreciated.

Will retest tomorrow

@lsafd still not sure

[lsafd]

Reconsidering what to do from here for the x230-hotp-verification platform, which doesn't compile if we go back to CBFS_REGION of 70000, not having enough space:

@tlaurion Isn't this the issue (From #667)? Do you just mean that you don't yet now how to solve this problem? Is there an older version or commit that I should clone from that is guaranteed to be working for x230-hotp-verification (or something similar)?

Thanks a ton for looking into this I realize you're pretty busy!

[tlaurion]

@lsafd : I will retest, but x230-htop-verification applied on top of https://github.com/osresearch/heads-wiki/blob/master/Clean-the-ME-firmware.md is supposed to work.

[tlaurion]

Can you confirm the behavior is still current with latest downloaded rom from circleci ?

Or a clean build

• make BOARD=x230-hotp-verification real.clean && rm build/* crossgcc
• make BOARD=x230-hotp-verification

[tlaurion]

So it means t430 and x230 are different....

[tlaurion]

Their CBFS region for x230-hotp-verification is CONFIG_CBFS_SIZE=0x710000 ins tread of CONFIG_CBFS_SIZE=0x800000 (https://github.com/osresearch/heads/pull/748/files#diff-540d604c350e8fd52c25559b642795fbR5)

Explanations here
Probably same problem would hit here if a t430-hotp-verification was existing, consuming more space in CBFS

[lsafd]

With the changed in #756 I was able to get things working. The only caveat is that about half of the time when I try to boot the screen stays black and my computer beeps loudly at me. However, the main issue has been solved, so I will close this issue.

Thanks a ton!

[tlaurion]

@lsafd that is not normal?

[lsafd]

I never experienced this problem when using the coreboot.rom file from x230 (as opposed to x230-hotp-verification), so my assumption was that that this is unusual. Also, I may make another issue for some problems related to luks tpm stuff I'm having.
