Hi Simon,
I'm trying to boot a Linux distribution of choice on the Acer
CB5-311-T9XM (nyan-big). I applied your patches from last Wednesday (v4,
without the display driver) and flashed the patched uboot to the
RW_LEGACY section after running this script with some objcopies
(https://chromium.googlesource.com/chromiumos/overlays/chromiumos-overlay/+/master/sys-boot/chromeos-bootimage/files/build_cb_legacy_uboot.sh).
Afterwards I jumped into the legacy section with Ctrl+L. Unfortunately
it just resets the board after some seconds. The reset cause is:
"reset-pin" and "hard". Find the EC UART output at the bottom. Using the
norrin.board pinmux instead of nyan-big.board didn't change the
behaviour (GPIO PI5).
Do you have an idea what I'm doing wrong?
Regards,
Simon Hoinkis

This is a reboot command - EC_CMD_REBOOT_EC. I wonder how/why your
U-Boot might issue that command?

From my investigation, Coreboot is issuing this reboot command, because
the Coreboot payload (which in my case is U-Boot) for some reason isn't
valid. With CONFIG_PANIC_HANG defined there is no UART output from the
EC at all.
Is a prepended SPL needed before the U-Boot+DTB payload?
When flashing U-Boot from the Chromium OS branch it gives some UART
output but freezes because SPI and MMC driver are not working properly
("emerge-nyan chromeos-u-boot").
Is this the best starting point to develop a working U-Boot?
Regards,
Simon

Normally you would hope for lots of AP serial output in this case.
