Hello, I recently bought an Asus KGPE-D16 board, with an Opteron 6238 and 4 Micron MT18JSF25672PDZ-1G4F1DD modules. Firstly I tried to boot with vendor BIOS but I don't get any output on VGA. I have a PCI Post Card and it seems it arrives to 3E and then I think it enters in a loop. I flashed Coreboot with default settings just to try to get some more useful logs. The result I think is more or less the same, it doesn't arrive to payload. Memory is installed in A2,B2,C2 and D2 slots. I spent multiple hours trying to figure where is the problem. Do you have any ideas? I attach the console log. Thanks in advance. Best Regards, - Eli

Coreboot + Depthcharge
by Mark Wylde 28 Feb '18

28 Feb '18

Hello I'm trying to put together a step by step guide of building and flashing coreboot to a Chromebook C201. If you look at the bugfixes part of my guide here (https://gist.github.com/markwylde/4061eab71fa1ec7a27c40a87499924c4#bugfixs), you'll see I've added two problems I had with the master branch of coreboot: 1. Depthcharge is not a payload. The `payloads/Kconfig` file doesn't have an option for Depthcharge. However if you add it and run menuconfig, selecting the new payload, everything works great (well apart from issues 2) 2. Coreboot/Depthcharge can't find a config file for veyron_speedy because `payloads/libpayload/configs/config.veyron_speedy` is not present. If I clone `payloads/libpayload/configs/config.veyron` then it works perfectly. When you run make you are going to get an error message, something like below: I'm almost certain my "fixes" aren't actually fixes, and I'm just doing something wrong, if you could correct me I'd be so grateful. Otherwise, if this is correct I'd be more than happy to try and workout submitting a pull request. Thanks a lot Mark

Re: [coreboot] [SeaBIOS] Mysterious "is VARVERIFY32INIT but used from" problem while trying to improve SeaBIOS

So, by default it would not include that code and would not raise a compile time error. If you configured seabios to build for coreboot and it didn't raise a compile time error then that seems like a build defect. -Kevin

Re: [coreboot] Atom c3000 Harcuvar and Intel ME
by Szafranski, MariuszX 27 Feb '18

Hi, In case of Harcuvar CRB we have 16M SPI flash: first 8M for ME (which is outside of CBFS) and last 8M for coreboot. We need to specify two things in coreboot config: - ROM chip size – 16M – physical size of SPI flash (needed for correct flash offset calculations inside coreboot code) - Size of CBFS filesystem in ROM – 8M (0x800000) or less 16M coreboot.rom file should be built with above config. You need to manually inject 8M ME blob at offset 0 into ‘coreboot.rom’ file. Or just flash last 8M from coreboot.rom into last 8M of SPI flash if ME blob is already there.

When configuring CB with menuconfig you have to select your platform and type in the path to your ME-binary-blob. The later has to be provided by you; meaning you have to extract the BIOS from the flash, extract the ME-binary using coreboot/utils, clean it with ME-cleaner (optional) and then build coreboot with your blob. The toolchain takes care automatically about the correct placement of the ME in the right address-ranges. I hope this was helpful. > Thanks, > Sumo

Re: [coreboot] Broadwell-DE hang in coreboot: mp_init.c

Hi Mark. I saw a very similar issue (similar because I have not analyzed it in detail due to missing time) with a 6 core Broadwell-DE. It hangs as well in SMM relocation. Same mainboard and coreboot binary with a 4 core Broadwell-DE does not have this effect.

Broadwell-DE hang in coreboot: mp_init.c
by mark pleso 26 Feb '18

26 Feb '18

Has anyone else seen a hang during coreboot booting on a Broadwell-DE? The issue appears to be in mp_init.c, in the function smm_do_relocation(). This is coreboot 4.7, but I think the issue exists in 4.6 as well. Enabling the printk will stop the hang. Or, just adding a wbinvd() instruction will stop the hang, and things proceed normally. Code is below. Any help would be appreciated. btw - This not a commercial motherboard. coreboot/src/cpu/x86/mp_init.cstatic void asmlinkage smm_do_relocation(void *arg) { const struct smm_module_params *p; const struct smm_runtime *runtime; int cpu; uintptr_t curr_smbase; uintptr_t perm_smbase; p = arg; runtime = p->runtime; cpu = p->cpu; curr_smbase = runtime->smbase; if (cpu >= CONFIG_MAX_CPUS) { printk(BIOS_CRIT, "Invalid CPU number assigned in SMM stub: %d\n", cpu); return; } /* * The permanent handler runs with all cpus concurrently. Precalculate * the location of the new SMBASE. If using SMM modules then this * calculation needs to match that of the module loader. */ perm_smbase = mp_state.perm_smbase; perm_smbase -= cpu * runtime->save_state_size; printk(BIOS_DEBUG, "New SMBASE 0x%08lx\n", perm_smbase); /* write cache to DRAM before calling relocation handler */ /* will stop hang */ wbinvd(); /* <<=== OR NEW INSTRUCTION w/o printk STOPS HANG */ /* Setup code checks this callback for validity. */ mp_state.ops.relocation_handler(cpu, curr_smbase, perm_smbase);}

Hi, In the coreboot build menu there is no option regarding the Intel ME integration. The 'coreboot.rom' file is the full SPI flash image or this file is suitable to replace the BIOS region of the SPI flash (0x00800000--0x00ffffff)? (i.e. in the SPI flash we already have a region for Intel ME firmware) Thanks, Sumo
