[coreboot] Booting issue --AMD Olive Hill plus mainboard

[Haleigh Novak]

​
Hello ,

cbmem is a utility located in .../coreboot/util/cbmem.
You will have to fully boot into linux to use this coreboot utility.
You will also have to have the ability to re-flash your coreboot rom because
there are some coreboot configuration changes.

What I do to install and run is as follows:

(Install)
1) Mount your coreboot source folder to the running system you wish to 
use the cbmem utility on.
2) Navigate to .../coreboot/util/cbmem folder.
3) Type "$ make install" into your terminal.
(cbmem should install on the system in the /usr/local/sbin folder.)

(Use - coreboot setup; requires a re-flash of your coreboot rom.)
1) In your coreboot folder run "$ make menuconfig".
2) Under the console tab: (explanations are above the configuration line 
and //[commented].)
//[Enable console output (below) by highlighting and typing 'y'.]
[*] Send console output to a CBMEM buffer
//[I had to increase the size for debugging (below).]
  (0x40000) Room allocated for console output in CBMEM
//[Set the default level to SPEW (everything) if it is not set like that already.]
   Default console log level (8: SPEW)  --->
With those settings you should be able to successfully run the cbmem utility
and get all the output you could need. If you wish to add debug statements 
anywhere you can do that as well, though it will require a re-flash of your 
coreboot rom again. All you need to do is add the following replacing <...> 
as desired anywhere in the coreboot code and it will be displayed in the 
cbmem output.
"printk(BIOS_INFO, "<statement> <variable print> <statement>.\n", <variable>);"

(Use - Run cbmem utility, you will need to be root for this.)
1) "cbmem -c" -or- "/usr/local/sbin/cbmem -c"

I included the microcode updates but no luck.



The PCI IDs seem to be correct for Mullins [Radeon R3 Graphics] (http://pci-ids.ucw.cz/read/PC/1002).
There is no serial port in the Olive Hill Plus board. What are my options?
Also how do i use this tool in util/cbmem/ ? I am using the default SeaBios as the payload.

unless you're dead certain you don't need them, include microcode updates. 
did you hook up a serial port?

These PCI IDs, are they correct? Is the VBIOS, which I don't know
anything about, executed? You need to have a way to see console
output, either using the board's serial port or - presuming the
mainboard boots to linux - through the utility found in util/cbmem/
