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.

Hi,
I am trying to bring up the AMD G series Olive hill plus mainboard with coreboot.
These are the options i have enabled in make menuconfig but I am not able to see anything on the screen when i power on the board. Could someone please let me know if I am missing something.

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/

Hi, Thanks for the steps, I appreciate it. If I understand correctly I would be able to use this tool when Linux boots with coreboot. But the issue I have is, coreboot not coming up on the board rather I am not sure if it's coming up because I don't see anything on the screen and there is no serial port on the board(except the cpu fan running). Any insight/suggestions would be appreciated.
