Hello,
I've been trying to boot grub installed on the hard drive using coreboot and SeaBIOS as a payload. The motherboard I'm using is Intel Mohon Peak. Also, I do not use VGA for output, only serial port. So, I included the sgabios into my rom file. Here is its layout:
$ ./build/cbfstool build/coreboot.rom print coreboot.rom: 8192 kB, bootblocksize 1024, romsize 8388608, offset 0x600000 alignment: 64 bytes, architecture: x86

The issue is, it looks like SeaBIOS does not load sgabios at all. Here is the SeaBIOS output, debug level 7 (I also put it in the attachment):

The last five lines is clearly grub output, only after this goes nothing and it seems to me that sgabios does not forward VGA output to the serial port.
So, how do I fix that? Am I missing something?

As I recall, Mohon Peak uses 0x2f8 for the console serial port. Did you set sgabios to output to 2f8 instead of 3f8 in sgabios.h?
sgabios.h:#define COM_BASE_ADDR 0x3f8

Thank you for your replies!
Just checked sgabios.h and changed serial port base address to 2f8. Somehow I missed it earlier, although I did set this parameter in both coreboot and SeaBIOS before. Sadly, I do not currently have access to Mohon Peak, so I can't really test this right now but, hopefully, I would be able to test this in a few days. Also, I'd like to clarify one more thing. Should Option ROMS parameter in SeaBIOS menuconfig be checked for sgabios to work? Are there any other nuances I should keep in mind?
Viktor
Hi Viktor, Yes, I think having option roms checked is probably required. The only other thing I'd recommend is to build SeaBIOS outside of the coreboot structure and pull it in as an elf payload. Building within coreboot is handy, but it doesn't offer the flexibility or control that you get building it yourself.

Kuzmichev,
Changing the seabios serial port base address, you should modify it via "make menuconfig" command, it's much easy and efficiency.
It's not recommended to modify the actual source files.

Hello Viktor,
I went thru your log file attached below, and I found a difference between our coreboot.rom which used the same Rangeley platform (Mohon Peak CRB).
would you please tell me how you generate this hightlighted mrc.cache file, I didn't find any configuration in 'menuconfig' or Kconfig files. My code base is 'RANGELEY_CB_POSTGOLD_001_20131218' which was downloaded from Intel website.
I've already googled 'mrc.cache' but hardly found much hits, what is this file for? could you please also give some hints :)
Thanks
May

From: Kuzmichev Viktor Date: 2014-12-25 16:45 To: coreboot Subject: [coreboot] SeaBIOS, serial output, grub, sgabios does not seem to load Hello,
I've been trying to boot grub installed on the hard drive using coreboot and SeaBIOS as a payload. The motherboard I'm using is Intel Mohon Peak. Also, I do not use VGA for output, only serial port. So, I included the sgabios into my rom file. Here is its layout:
$ ./build/cbfstool build/coreboot.rom print coreboot.rom: 8192 kB, bootblocksize 1024, romsize 8388608, offset 0x600000 alignment: 64 bytes, architecture: x86

The issue is, it looks like SeaBIOS does not load sgabios at all. Here is the SeaBIOS output, debug level 7 (I also put it in the attachment):

The last five lines is clearly grub output, only after this goes nothing and it seems to me that sgabios does not forward VGA output to the serial port.
So, how do I fix that? Am I missing something?

Hello May,
My FSP is from Intel website too, but it's called slightly different - 'RANGELEY_*FSP*_POSTGOLD_001_20131218.fd'. Also, I have the book called "Embedded Firmware Solutions" in which the purpose of mrc.cache is described as "For saved memory configuration data." Later in this book there is another mention of this file in the "State Machine Callbacks" section: "Each state has an Entry Callback and an Exit Callback, which may be used by any coreboot code to hook any state. For example the Baytrail FSP mrc.cache is saved during the table write state, after all devices have been setup. Enter State -> Entry Callback -> Execute State -> Exit Callback -> Next State" I can also attach my configuration file if it will be more convenient for you.

Hello Viktor,
I went thru your log file attached below, and I found a difference between our coreboot.rom which used the same Rangeley platform (Mohon Peak CRB).
would you please tell me how you generate this hightlighted mrc.cache file, I didn't find any configuration in 'menuconfig' or Kconfig files. My code base is '*RANGELEY_CB_POSTGOLD_001_20131218*' which was downloaded from Intel website.
I've already googled 'mrc.cache' but hardly found much hits, what is this file for? could you please also give some hints :)
Thanks

Regards, Viktor Kuzmichev -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
Hello,
So, after editing sgabios.h I saw that sgabios actually loaded. As I did not disable serial output in SeaBIOS and Grub, I got duplicate characters and lines. I know, if I disable all serial output, that should most probably solve it. However, I still need debug messages, so I decided to use only serial input/output. The only issue with this that I had before is that Grub was configured to load splashimage which, it seems, interfered with the serial output. So, when I disabled it, it loaded just fine. And now I have the following setup controlled completely by serial input/output: coreboot -> SeaBIOS -> Grub -> Linux. There is just one little annoying issue now. SeaBIOS does not respond to F12 via serial IO.

Hi Viktor, Yes, I think having option roms checked is probably required. The only other thing I'd recommend is to build SeaBIOS outside of the coreboot structure and pull it in as an elf payload. Building within coreboot is handy, but it doesn't offer the flexibility or control that you get building it yourself.

Hello,
I've been trying to boot grub installed on the hard drive using coreboot and SeaBIOS as a payload. The motherboard I'm using is Intel Mohon Peak. Also, I do not use VGA for output, only serial port. So, I included the sgabios into my rom file. Here is its layout:
It should have worked. How did you build SeaBIOS, what SeaBIOS config did you use, and what changes have you made to SeaBIOS?
-Kevin
As I recall, Mohon Peak uses 0x2f8 for the console serial port. Did you set sgabios to output to 2f8 instead of 3f8 in sgabios.h?
sgabios.h:#define COM_BASE_ADDR 0x3f8
Martin
Thank you for your replies!
Just checked sgabios.h and changed serial port base address to 2f8. Somehow I missed it earlier, although I did set this parameter in both coreboot and SeaBIOS before. Sadly, I do not currently have access to Mohon Peak, so I can't really test this right now but, hopefully, I would be able to test this in a few days. Also, I'd like to clarify one more thing. Should Option ROMS parameter in SeaBIOS menuconfig be checked for sgabios to work? Are there any other nuances I should keep in mind?
Viktor
Hi May, you might have already gotten past this, but I thought I'd comment. The codebase you're working from is intel's proof of concept implementation. I don't remember if they have the MRC cache enabled. For Rangeley/Avoton platforms though, saving and restoring the MRC cache required, not optional as it is on many other FSPs.
The MRC cache is for saving the state of the memory controller. Other FSPs require that the MRC data get saved and restored for S3 resume and for "Fast Boot". For Rangeley it's required that it get restored every time. If the MRC cache isn't restored, the system gets reset an additional time on boot. If the platform doesn't have the hardware for a full power down sequence (blade systems are the example I saw), then the system will hang on reset about 30% of the time.
If the code to save and restore the MRC cache isn't available in the codebase you're using, I'd recommend switching to a codebase that does.

Hello Viktor,
I went thru your log file attached below, and I found a difference between our coreboot.rom which used the same Rangeley platform (Mohon Peak CRB).
would you please tell me how you generate this hightlighted mrc.cache file, I didn't find any configuration in 'menuconfig' or Kconfig files. My code base is '*RANGELEY_CB_POSTGOLD_001_20131218*' which was downloaded from Intel website.
I've already googled 'mrc.cache' but hardly found much hits, what is this file for? could you please also give some hints :)
Thanks
