It would be nice if we could test coreboot images in VirtualBox, see
http://virtualbox.org/.
VirtualBox does not (yet) provide a simple mechanism to use a different
BIOS in their emulated machines (something like "-L" in qemu). Instead the
BIOS image (a custom bochs BIOS + LGPL'g VGABIOS) is converted to C code
(an array of bytes, or the like) and merged into the VirtualBox
executable.
The relevant files are
{{{
src/VBox/Devices/PC/DevPcBios.cpp
bldprogs/bin2c.c
}}}
if someone want to hack VirtualBox to easily support using coreboot images
instead of their usual BIOS.

I wanted to know which physical port of my multiple USB controllers have
the debug capability. There was no way to find that easily, so I created
a tool which will do most of the work for the user.
Example output:
The following PCI devices support a USB debug port (says lspci):
0000:00:1d.7
The following PCI devices support a USB debug port (says the kernel):
0000:00:1d.7
PCI device 0000:00:1d.7, USB bus 3, USB physical port 1
Currently connected high-speed devices:
/: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/6p, 480M
|__ Port 2: Dev 20, If 0, Class=stor., Driver=usb-storage, 480M
The output can be improved, but it's a good start.
Regards,
Carl-Daniel

Hi list(s),
Here's my second attempt at routing the previously mailed png of my schema.
It was a lot trickier to route then my previous version, but I think it
worked out!
As mentioned, S1 and S2 need to be shorted if U3 is to be omitted. RN1
should be 10k or ideally 100k, as Peter mentioned earlier.
Hopefully there's no obvious mistakes and can start working on
alternative layouts (so it is insert-able in different angles).
DRC Check fails on S1, S2 and U3. It thinks the distance is to shallow.
That said, DRC check passes when I set the copper width/distance to
7mil's instead of the current 8 mils.
I'm planning on having these PCB's manufactured by Seeed studio and
their minimal width is much smaller.
Minimum trace width: 6mil
Minimum trace/vias/pads space : 6mil
Minimum silkscreen width : 4mil
Minimum silkscreen text size : 32mil
I've used a grid size of 10mil and distances of 8 mils, as I didn't want
to rely on the minimum of seed. The silkscreen I positioned using a grid
size of 5 mil's however. Not sure what they mean with a 'minimum
silkscreen text size' however.
Anyhow, feedback greatly appreciated, so I can start working on
alternative layouts :)
#186: 3com 3c905tx / gpxe boot problem

Although (or: just because) novice in the field, I encountered some
problems with netbooting with coreboot.
Mobo's tried: Asus P2B, VTech with bios id ITE8671-2A69KV3IC-00. All
mobo's boot '''harddisk''' fine with Asus P2B / Gigabyte GA-6BX{CE}
respectively.
NIC ROM is started, and loads the kernel by tftp. This is vvvveeeerrrryyy
slow! Although loading, the kernel is never able to start itself. Same
kernel on HDU is no problem at all (GRUB2)
Note: the gpxe-image is on the nic, coreboot payload is seabios.

I try to get coreboot working with asrock 880g pro3 board.
First problem: spd eprom say that memory ddr1600 capable, but it is not
so, is there are right way to limit memory frequency at ddr1333?
Other problem, may be related as machine with broken memory are very
unpredictable: boot process stop with "It is not SB800 or SB810"
message. I try to enable sb850 by this patch, but looks like it is not
enough, most of time coreboot does not detect hdd. Sometimes in very
rare case it is possible to boot from sata. Are sb850 supported by
coreboot?

Thanks for attaching the log for me.
Some recent commits to coreboot master seems to have solved my problem
with the pci scan hang. Now I don't have to hack around it any more.
However it still freezes after it's done (?) loading seabios.
I have uploaded my changes to https://github.com/DarkDefender/coreboot
if anyone want's to look at them.
I've tried to enable more debugging options in the "OptionsIds.h" for
AGESA but it doesn't seem to do anything.
The asserts are triggered druing boot are still the same as before.
I've tried to look at it but I didn't really understand what I should
change to solve them.
Dear coreboot folks,
I am planning on working on the ASRock E350M1 a bit. As it is similar to
the AMD Persimmon board, it would be awesome to have the Persimmon logs
for comparison. Could you please attach them to your reply with a note
what GNU/Linux distribution you use and what Linux version.
Thanks,
Paul
Current status.
Raminit: works with delays/printfs currently in place, 1-ranked memory
populating one slot. Didn't test in any other config yet (either
removing debug and delays or trying other type of memory). Looks like
resulting settings are slower than original BIOS due to me skipping some
of advanced training.
EHCI and AHCI work in GRUB shell.
VGA option ROM works
keyboard works.
LAN card doesn't show up in lspci
ACPI tables are visible in GRUB but mysteriously disappear when Linux is
booted (working theory is that some other device got mapped over).
Linux boots into debian netinst (images taken from USB stick).

ARM: fix the ldscripts so that exit/enter stage work correctly.
Remove the spurious creation of a start symbol, and use the
stage entry symbol directly.
