New subject: Please upload board status Asus AM1I-A

      Hi Gergely,
Thank you for your config. Now I have coreboot + SeaBIOS perfectly working.
Console speed is now "normal" :-)
These are the changes between the two configs:
-------------

< # CONFIG_PCI_OPTION_ROM_RUN_YABEL is not set

< # CONFIG_VGA_TEXT_FRAMEBUFFER is not set
556c553
< # Serial port base address = 0x3f8
---
...
# Serial port base address = 0x2f8
581,583d577
< CONFIG_POST_DEVICE_NONE=y
< # CONFIG_POST_DEVICE_LPC is not set
< # CONFIG_POST_DEVICE_PCI_PCIE is not set
--------------
I made some tweaks to the configuration, added VGA output before 
payload, a nice bootsplash, etc..
Other considerations:
VGA Device PCI IDs are 1002,9830 (The default 1002,9836 does not get 
output).
Memory has to be located firstly on second slot (yellow DIMM_A2). If not 
you get AGESA_FATAL_ERROR. I only have one module.
Please, find attached a working config.txt and console.log. Coreboot 
revision is 4.7-294-g2db6fbc47b.
If you verify these changes are working for you is it possible to change 
the defaults in Kconfig?
Thank you very much.
Best regards,
-- Eli

Strange, the log you shared looked less verbose to me than expected 
but seems like I was wrong. Anyway, you might find an example on a 
full debug log here [1].
I have a small build script I use to build coreboot for my board, 
please find it attached.
The version currently running on my box is 4.6-2554-ga1b4c94.

Thank you for your kind reply Gergely.

I think the cable is not the problem, I have been using it for
years and it's intact.

I am using a usb dongle but not a cheap one. Tomorrow I will try
with another cable and a real COM port. Just to be 100% sure.

Console is fast at the very first time (just the "normal") but
after two seconds it becomes extremely slow.

Please, can you say me which is the git revision you are using?

The console log I attached is from a SPEW debug level, not
corresponding with the config.. I tried several configs today :-) .

Is it possible to share your config with me?

Best regards,

Eli

Hi Eli,

I've been using Coreboot on my board for several weeks, it is
serving as an HTPC running 24/7 and it's working perfectly stable
which suggests the firmware should be free of bugs. It is likely
that you are facing some configuration or hardware issue here.

I didn't see any issues with the serial output while working with
the board once the SuperIO chip started to work. Make sure the
cable you use is intact and try to attach it to another machine.
At the time I was working with my board, I used a Dell Port
Replicator with a native COM port so I could use a standard
null-modem cable and it was working flawlessly. In case you use a
USB serial adapter, try replacing it or attach the serial cable
directly to a COM port if you have one available.

Also, please enable debug_level=Spew as it seems the console log
you attached comes from a less verbose setting and therefore it's
not as useful as it should be.

Note that the VBIOS image is executed by SeaBIOS which means you
won't see anything on your display until the payload is executed.

If all else fails, you can still attach a POST debug module to
the LPC header of the board [1] which can help a lot to find out
where the boot process hangs.

Feel free to contact me if you need some more help or
information, I'm happy to assist!

Regards,
Gergely

    Hello,

    I'm trying to use Coreboot in an Asus AM1I-A board recently
    ported by Gergely Kiss (thank you!).

    I am using the default config settings and added vga rom
    extracted with UEFITool from the vendor bios.

    After flashing and booting I get no output from vga.

    Serial console is extremely slow too (30 minutes to write the
    log)

    I attach the coreboot console log, config and cbfs.txt.

    Any hints?

    Thanks in advance.

    Best regards,
