Hi Patrick Yes i rebuild the Compilers after every coreboot build. So the steps where 1.) Git bisect start 2.) Git bisect good <commit> 3.) Git bisect bad <commit> 4.) Make crossgcc-i386 5.) Make 6.) Check the coreboot Image live on physical alix 7.) Make clean 8.) Make crossgcc-clean 9.) Git bisect bad/good 10.) Start over at step 4 again and so on… until found breaking commit.

Alix 2d13 coreboot breaking source
by Reto Rayen 08 Apr '16

08 Apr '16

Hi guys Finally i found out, which git commit broke coreboot to build for a «Alix 2d13». I used «git bisect» recommended by «PaulePanther» in october 2015 to identify the commit. A doc about the different git commits and their results can be found here: https://file.youngsolutions.ch/index.php/s/g2cixjqepvTwJhR Commit which breaks coreboot for successfull buid: 53c388fe6dfb4fc4ffcee6c58345d353c6ec33bf (crossgcc: Update toolchain) So what the next steps, to get coreboot working with the latest build for Alix 2d13? Thank your guys, for your help so far. Kind regards Reto Rayen

Re: [coreboot] Linux as payload

Here are a few pitfalls you should mind: * Fedora's prebuild kernel doesn't work any more. You likely want to compile it yourself. * Self compiled kernel does work. Tested versions are: Linux 4.1, 4.2, 4.3, 4.4 * I don't enable pre kernel GPU initialization The screen is black until the drm kernel module is started. * Make sure to add support for your root filesystem (ext2/3/4 is default) Others need to be compiled in, or you need to provide a initramfs containing the kernel modules for the filesystem. I compiled them in, instead of using a initramfs. * Make sure to give a working root path (PARTUUID is fine, too) * Initramfs isn't used by me, so I can't tell if it's working, but it should. Kind Regards, Patrick

You'll want both. The file system is what goes in the initrd config option Add a payload (A Linux payload) ---> (bzImage) Linux path and filename () Linux command line () Linux initrd Martin On Thu, Apr 7, 2016 at 10:31 AM, daoud yessine <yessine.daoud.92(a)gmail.com> wrote: > Hi > > how to build coreboot with linux as payload ? > I need Bzimage only ? > what about the file system ? > > thanks > ᐧ > > -- > coreboot mailing list: coreboot(a)coreboot.org > https://www.coreboot.org/mailman/listinfo/coreboot >

Re: [coreboot] Regarding offset adjustment for building coreboot.
by Martin Roth 08 Apr '16

08 Apr '16

Not knowing which platform this is makes it a little harder to determine what's locked in place. We'd also need to know if this is getting built from the top of the coreboot.org tree, an old coreboot.org commit or an private repo with many changes from coreboot.org. Microcode should be able to be placed in any area for most of the FSP platforms, but it might need to be changed in Kconfig or the Makefile so that the system knows where it is. You might also want to look at just including the necessary microcode patches for your particular board if possible. Many of the FSP platforms include all available microcode back to some pre-production parts by default. The mrc cache can be moved at build time, but needs to be on the correct boundary, and CANNOT have anything else in the same sector on the flash. The cache gets erased, so moving it to an odd boundary or putting other things in the same sector will cause interesting issues. The FSP itself can also be moved, but it needs to be rebased with intel's FITC tool, and coreboot needs to know the location at build time. Finally, you might want to look at leaving out the small or non-essential files, and add them after the build completes to make sure that there is contiguous space for your essential components: bootsplash.img, config, fspd.bin and cmos_layout.bin Martin On Fri, Apr 8, 2016 at 4:29 AM, Patrick Georgi via coreboot <coreboot(a)coreboot.org> wrote: > 2016-04-08 11:17 GMT+02:00 Nico Huber <nico.huber(a)secunet.com>: >> you also stripped: >> >> fallback/payload 0x1b140 payload 769955 >> >> I guess he means that a fresh build with a bigger (865KiB instead of >> 752KiB) payload fails. > Of course you're right.
