[coreboot] serial console : no keystroke

[Maxime de Roucy]

Hello,

I am trying vanilla coreboot/SeaBios on an pc-engines apu1d4 :
http://www.pcengines.ch/apu1d4.htm

The board natively use a modified version of coreboot, the sources are
available at http://www.pcengines.ch/howto.php#CoreBoot (coreboot_14090
8.tar.gz)

I use a usb-SR232 adapter to connect on the board.
I use minicom and picocom. Both are working fine.

BUT

When I use coreboot vanilla (master) with SeaBios vanilla (master, I
also tried 1.7.5), when I get to "Press ESC for boot menu" I can't send
keystroke to SeaBios through the serial console.
I have to plug an USB keyboard and press ESC on it.

I tried scancode (F10, F12, Q (0x10)) same problem.
I disabled hardware and software flow control on minicom.

In fact, SeaBios doesn't get ANY keystroke from the serial port.
I can press any keyboard key in minicom/picocom the message "Press ESC
for boot menu." stay until timeout (DEFAULT_BOOTMENU_WAIT) (I set
etc/boot-menu-wait to 90000 to verify that… so I am pretty sure of it).

Furthermore, after I enter the boot menu via usb keyboard I can't
choose anything from the menu through minicom/picocom.
I have to use an USB keyboard.

When I get in the OS (tinycore Linux), minicom/picocom input works.

I don't have the problem with the modified coreboot/SeaBios from PC
-Engines.

At first I thought it's a SeaBios problem but the keystroke code part
(src/boot.c) are the same in vanilla SeaBios and PC-Engines SeaBios.

PC-Engines sources don't have .config files (nor for coreboot neither
for SeaBios) but have build/config.h and out/autoconf.h.
I tried to look for some interesting difference between vanilla and PC
-Engines sources for those file but my coreboot/SeaBios knowledge
weren't enough to spot anything.

Can anyone help me ?

Since I don't know if the problem relies on coreboot or SeaBios I post
this on both mailing-list.

I attached to this mail :
* my .config coreboot file
* my build/config.h coreboot file
* my payloads/external/SeaBIOS/seabios/out/autoconf.h SeaBios file
* PC-Engines build/config.h
* PC-Engines SeaBios autoconf.h
