Fitlet-B

Hi, I adquired a Compulab Fitlet B machine [http://www.fit-pc.com/web/products/fitlet/]. I contacted to Compulab in order to know how to install CoreBIOS to it. They sent me this message: > Hi Xavier, > > We’re in contact with Coreboot community in Finland that are testing and > checking feasibility of the fitlet with their code. > The moment they provide us with answers we will definitely publish them. > > Thanks, > Maxim. Can you confirm that? In which point is this porting? Thanks, Xavi

coreboot use SeaBIOS as paylod fail
by Yu-Cheng Liu 16 Jun '15

16 Jun '15

Hello, When I tried to use QEMU to run COREBOOT(using SeaBIOS as payload), I got some problems and can’t start the computer successfully. Below are the steps I used to build disk.image and corboot.rom. Also the command to start QEMU. Please help me figure out what’s wrong with my steps. Thank you in advance. (PS.: My platform is 64-bit Ubuntu. Version is 14.04)

Sandybridge: native ram init
by Patrick Rudolph 15 Jun '15

15 Jun '15

Hello, I'm trying to get the GA-B75M-D3H to work, but I'm stuck at native ram init. It stops at "c320c discovery failed". I figured out that the lower 4 lanes 0-3 are always erroneous in this test. The upper 4 lanes are working as expected and return errors depending on the skew chosen. All previous tests work fine, so I guess it's not a hardware defect. The PC boots using the stock UEFI. Do you know a "good" RAM module/vendor that is known to work with this board ? I tested * Team Xtreme 2x 4GByte DDR3-2133 * Crucial 1x 2GByte DDR3-1600 but they show the same error message. Do you have any further tips to debug this issue ? Regards, Patrick

make crossgcc error
by Richard Simpson 15 Jun '15

15 Jun '15

Hello, I have recently purchased a Lenovo T60 with the hope of installing coreboot and I have to say that the process is making me mighty nervous. I have extracted the default bios and the VGA bios (it has an ATI video controller). I am running CentOS 7. I have run 'make menuconfig' and that seems to have worked, but when I try 'make crossgcc' I get the following error: Warning: no suitable compiler for arm. Warning: no suitable compiler for arm64. Warning: no suitable compiler for mipsel. Warning: no suitable compiler for riscv. ERROR: Missing tool: Please install patch (eg using your OS packaging system) make[1]: *** [build-i386-without-gdb] Error 1 make: *** [crossgcc-i386] Error 2 I have no idea what to do about this. Thanks,

Dear coreboot folks, Am Donnerstag, den 26.02.2015, 17:23 +0200 schrieb Emilian Bold: > I was trying to duplicate a coreboot build back in November and I noticed I > couldn't get my ROM file to be identical to the one I found online. > > It seems that coreboot doesn't have reproducible builds yet. > > Debian has been looking into this for a while > https://wiki.debian.org/ReproducibleBuilds and I think coreboot should > adopt this concept. […] Holger Levsen joined #coreboot(a)irc.freenode.net yesterday to report that he integrated coreboot into the reproducible builds infrastructure [1]. After configuring the used build script [2] to build without a payload, nice ionice -c 3 \ bash util/abuild/abuild --payloads none || true # don't fail the full job just because some targets fail it looks like most boards are passing the test now [1]. Big thanks to Alexander (lynxis) for submitting the necessary patches! The only exceptions are the six boards below. * a-trend_atc-6220 (256K) is unreproducible. * a-trend_atc-6240 (256K) is unreproducible. * google_nyan (4096K) is unreproducible. * google_nyan_big (4096K) is unreproducible. * google_rush (4096K) is unreproducible. * google_rush_ryu (8192K) is unreproducible. Also, as a side node, SeaBIOS also supports to be built reproducible since commit 624e8127 (build: Support "make VERSION=xyz" to override the default build version) [3], though not by default. So the coreboot build system, building the SeaBIOS payload, would need to be adapted, if a reproducible build with the SeaBIOS payload is required.

With 4.0-9975-g1f38d79 only one board is listed [1] as not reproducible buildable and that is Google Urara [2]. -3 00000020: 0000 009a 0799 afe7 009b 1d3c 0020 bd27 ...........<. .' +3 00000020: 0000 009a 0719 ae47 009b 1d3c·0020·bd27 .......G...<. .'

Re: [coreboot] Flashrom won't work with DediProg SF100 fw 6.5.03

* Steve Goodrich <steve.goodrich(a)se-eng.com> [150602 20:38]: > I got the Chromium version of flashrom to work, but it takes 20 minutes to > flash/verify the 8 MB device. So, while "working" is far better than "not > working", it is a bit sluggish. :-) I seem to remember there are two ways flashrom can program through a dediprog, the slow one that always works, and the fast one that we didn't know which chips it's working with, so it defaults to the slow path.
