Hi all, Has anybody been able to boot Bayley Bay CRB with the latest coreboot source from the git tree? We have a Bayley Bay CRB (E3827, B3). With coreboot Baytrail fsp support pulled from about two weeks ago and some help from Martin, I was able to see coreboot booting and fsp loaded, but was having issues with SeaBIOS. I pulled latest source tree this morning and found out it does not boot any more on my board. Port 80 stuck at code 0x43, no console output. Here are my steps: 1. Build coreboot toolchain. 2. Build coreboot.rom using fsp and microcode from BAY_TRAIL_FSP_KIT downloaded from Intel fsp site. 3. Flash coreboot.rom to top 2M of the 8M flash. I was getting the usage information here and there from the discussion threads and perhaps I missed something? It would be great if somebody could post the detailed procedure. Thanks! Wen

Re: [coreboot] IMB-A180 based design question regarding POST codes during boot failure

I think it is incredibly embarrassing that coreboot has code which requires manually messing with #defines depending on something so fundamentally dynamic as memory configuration. What is that about, really? //Peter

IMB-A180 based design question regarding interrupts

by Mark C. Mason

We are testing coreboot with our new IMB-A180 based AGESA design, and DMA interrupts are not functioning. I am looking into the Coreboot Options, but is there a recipie for enabling legacy interrupts in AGESA? We configure in Linux at IRQ 17. Thanks in advance, Mark Mason Engineering Design Team

IMB-A180 based design question regarding POST codes during boot failure

by Mark C. Mason

We have a board that is failing to boot, and we think there is a memory problem on the board. I have a trace (od -t x4 dump) of the POST codes: 0000000 01 10 10 a0 a1 a1 30 31 34 37 c0 b1 c1 38 39 c4 0000020 71 72 75 76 77 78 79 7b 7a 7c 90 91 91 58 5a 01 0000040 10 10 a0 a1 a1 34 37 c0 c1 38 39 c4 7d 7e 58 5a 0000060 58 58 5b 5b 5c 5d 5e 92 94 95 c5 40 01 0a 46 42 0000100 c6 44 96 97 98 03 02 3e 3f 47 48 49 3d 08 00 00 0000120 40 41 10 50 43 d6 d7 d6 d7 d6 d7 d6 d7 d6 d7 d6 0000140 d7 d6 d7 d6 d7 d6 d7 d6 d7 d6 d7 d6 d7 d6 d7 d6 0000160 d7 d6 d7 d6 d7 d6 d7 41 Using the Sage SmartProbe to perform source-level debugging, we find that the process is stuck in an infinite loop in this code: while (CurrNodeOffset != 0) { CurrNodePtr = (BIOS_BUFFER_NODE *) (BiosHeapBaseAddr + CurrNodeOffset); if (CurrNodePtr->BufferHandle == AllocParams->BufferHandle) { return AGESA_BOUNDS_CHK; } CurrNodeOffset = CurrNodePtr->NextNodeOffset; /* If BufferHandle has not been allocated on the heap, CurrNodePtr here points to the end of the allocated nodes list. */ } with CurrNodeOffset == -1 (0xffffffff). The code is from around line 103 in coreboot/src/northbridge/amd/agesa/family16kb/fam16kb_callouts.c I plan to continue the source-level debugging to try and track this down, but as I am new to Coreboot, any guidance you may have to offer would be much appreciated.

Atom E3815 processor - reporting incorrect PCI device id

by Mike Hibbett

Hi all, I have two B3 stepping E3815 processors, one is reporting a PCI device id of 0x0f00 ( as expected ) but another is reporting 0x0000. I can work round that in the BAYTRAIL_FSP CoreBoot build but cannot install Linux, and I'm guessing that having a wonky device id may be involved. Has anyone else seen this and know the work around? I can't see anything about it on the Intel IBL. Cheers, Mike.

Building coreboot and SeaBIOS from Windows

by Scott Duplichan

The coreboot build environment for Windows is once again working: http://notabs.org/coreboot/windows-build.htm (release 013). SeaBIOS also builds, but requires a change not yet in SEABIOS_STABLE. Use SEABIOS_MASTER for now. Thanks to Kevin for that change: http://code.coreboot.org/p/seabios/source/commit/ec44fac1f69bd3d513204a6192… Thanks, Scott

MMCONF (again) issues on Fam 10H

by Denis 'GNUtoo' Carikli

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, The fact that my M4A785T-M got unusable with master pushed me to retest that patch: 23:58 < PaulePanter> GNUtoo-irssi: git fetch http://review.coreboot.org/coreboot refs/changes/41/4541/1 && git checkout FETCH_HEAD So instead of doing a checkout, I did a cherry-pick of the patch on top of master, and I've attached the log. I don't remember what happened but we probably deadlocked each other. What probably happened is that you wrote a mail to the mailing list, which I didn't respond to because I responded trough IRC. I probably didn't even see the thread because with my mali setup, the coreboot mails are now automatically in a coreboot folder, and since I don't work on it right now, I probably didn't look it up. M4A785T-M status: - ----------------- Here is the difference of status since I touched it last time(probably about one year ago). The new status of the M4A785T-M is on top of a patched old master. * The mmconf issues are still there on master * Ram init got very unstable lately, lately I have freeze once booted, and before I had difficult boot (sometimes it reseted during the boot). * 4G of RAM doesn't work, most probably because of the unstable RAM init, because it has the same reboot symptom, but way more frequently. * The sound card now works!
