For the short term: Consider updating libpayload in your tree to the latest version while keeping coreboot in your current state. This works since these are really two independent projects. However you will fare better long term by keeping your coreboot tree close to upstream. Regards, Patrick

Hi Zoran, Glad that you found the source of the problem! Stojsavljevic, Zoran wrote: > I need to direct relevant people to make this adjustment and commit > these changes for x86 to latest Coreboot git tree. If you are distributing coreboot then it would be significantly easier for you to work with the community with the goal to have your needed functionality available in the public coreboot git. Like with other open source projects. Kind regards //Peter

FILO's master branch was adapted to an i386->x86 rename in December 2012. Please retry building FILO in a coreboot master checkout (so you get the master libpayload as well). These are no ABI changes, so a FILO payload built that way is still usable with an older coreboot tree. Regards, Patrick

I don't know about your environment but it seems to me that the FILO code is buggy. It is not so popular anymore so it's possible that there is some bitrot. Hopefully you can help look into what the problem is. > Did somehow I misconfigured coreboot/payloads/libpayload > (it was compiled prior these steps)? I'm not sure what you mean, but yes it has been possible to build FILO in the past. If you can it would be great if you use git bisect to find the commit which broke the build. //Peter

Integrating FILO with Coreboot

Hello to Coreboot community, Went to filo Coreboot page: http://www.coreboot.org/FILO As written, executed the following: cd coreboot/payloads git clone http://review.coreboot.org/p/filo.git cd filo make menuconfig make produces several errors, on the way, so I did temporarily fix it: [zoran@localhost filo]$ diff -c Makefile Makefile.orig *** Makefile 2013-08-16 14:54:09.314253711 +0200 --- Makefile.orig 2013-08-16 15:17:06.190593523 +0200 *************** *** 91,98 **** ARCHDIR-$(CONFIG_TARGET_I386) := x86 CPPFLAGS := -nostdinc -imacros $(obj)/config.h ! ## CPPFLAGS += -I$(INCPAYLOAD) -I$(INCPAYLOAD)/$(ARCHDIR-y) !

Other than that: Optimizing the common code is better than a special case. memmove won't change much, so that's a stable interface, but you never know what will happen (and few people will be able to test their changes on Vortex86).

The public datasheet is here: http://www.intel.com/content/www/us/en/chipsets/6-chipset-c200-chipset-data… The newer products (Acer C7, Lenovo X131e, and HP 14-c050 Chromebooks) use the 7-Series/C210 chipset. The public datasheet is here: http://www.intel.com/content/www/us/en/chipsets/7-series-chipset-pch-datash… It's been a while since I've looked at the huge matrix of codenames for those generations of chipsets, but IIRC Cougar Point is in there somewhere...

Where can one download the sources and build toolchain for the firmware images Google ships these products with? This looks a lot like license terms violation to me, when customer cannot recreate the binary. I think I have asked at #coreboot a couple of times how to track the revision tags or commit hashes from a production image to the sources. And have gotten no answer. And to be clear, I am _not_ referring to the sources of the systemagent binary blob of these Intel chipsets here. Kyösti
