Coreboot AGESA used on AM1 doesn't support IOMMU :[ and of course the
default bios doesn't either. There is no IOMMU device in lspci/dmesg so

Seems like there's little information publicly available about the AM1
platform. As you can see here [1] there's plenty of information available
for the Bolton FCH which is used in newer APUs, while the Hudson FCH is
basically undocumented.
The BKDG for the Kabini platform [2] mentions two registe
Has anyone figured out if the AM1 platform has IOMMU? the OEM bios on
the AM1ML has an option for it but it doesn't work.
The lack of that is really disappointing.
I am also unable to locate the spec sheets for the AM1 platform that
would confirm this.

Hi Gergely,
Sorry, I didn´t know the PCI IDs are APU depending. I´m using an Athlon
5350.
Yes, the differences are minor. Only UART used and TTYS0_BASE address.
Thank you for clarifying the memory requirement. I didn´t see it in the
manual :-( .
Maybe you can change the defaults for CONFIG
Hi,
taking a look at the diffs, I can't see any major difference.
CONFIG_USE_BLOBS is y by default so setting it to y is not really useful.
The only notable difference is that you used COM1 for console output
instead of COM2 (which is the port soldered on-board). However, this does
not seem to exp
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:

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
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
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
