As I am still chasing how to enable SCSI termination on the board,
Due to the conversion, please always write if that worked with romcc,
that means, a regression with C environment bootblock.
I've recompiled a few more times. Therefore I was able to upload two
more clean board statuses, one with serial enabled and one without
as you asked.
Thank you. Though I only see one more upload after the one I referred to.
$ git log --oneline -2 asus/p2b-ls

Without serial (`CONFIG_CONSOLE_SERIAL is not set`) has a total time of
2.9 seconds compared to 5.7 before.
Unfortunately without serial it still takes 2.5s in the romstage, and
I can visually see the serial output going much slower than in
ramstage. We should check the serial enabling code in romstage or
even bootblock.
Is that a regression compared to romcc bootblock?
Also PS/2 keyboard init and sometimes video init is still finicky.
Ditto. Regression or not.
There are times when keyboard does not respond before the linux
kernel is completely done,
Maybe that can be debugged in SeaBIOS, which you use as payload. Please
increase the debug level for SeaBIOS, and post the logs from the working
and non-working cases. (Please start a separate mailing list thread for
that.)
and that could also be preventing my SCSI
BIOS (extracted as is from factory image) from running through as it
watches for a key combo to enter its setup interface.
Did that work with romcc. Please paste verbose SeaBIOS logs.
What is the commit that I should branch off of to get my romcc
romstage back?
I assume it is the parent of commit 1fa240a3 (cpu/intel/slot_1: Move to
C_ENVIRONMENT_BOOTBLOCK) [1], so commit df0c731e (mb/Kconfig: Add a
warning on boards with a ROMCC_BOOTLOCK). Please test df0c731e, and
upload the logs to the board status repository too.
Kind regards,
Paul
