Unfortunately, Coreboot is still not mainstream, netiher is Lemote. UEFI is the current mainstream system firmware, for Intel systems, and ramping up quickly for ARM (though not yet on Android-based devices yet, AFAIK). Intel's Tunnel Mountain UEFI dev platform lets you flash your own UEFI-based firmware, and mainly targets firmware IHVs. http://www.tunnelmountain.net/ http://uefidk.intel.com/develop/workstation-development-kit The Intel Atom-based MinnowBoard is a new UEFI dev platform, and it's Linux-based, and targets hackers; it uses Intel's definition of "Open Hardware", mainly meaning no NDAs involved. It is much cheaper and smaller than the above box. http://minnowboard.org/ http://uefidk.intel.com/content/minnowboard-uefi-firmware Both of these boxes let you reflash your system firmware with your custom build of BSD-licensed TianoCore UEFI. For Linaro's Linux/ARM device targets, Linaro also has a fork of Tianocore, and ships their own images. You can use the Linaro targets and modify this forked Tianocore firmware, as well, but it requires a bit more ARM-centric eLinux skills. https://wiki.linaro.org/ARM/UEFI <soapbox> There is a large OEM/ODM/IBV/IHV/ISV ecosystem that currently runs the hardware, and it is UEFI-centric. IMO, focusing only on fringe Lemote/Coreboot technology is not a good bet. Personally, I wish EFF/FSF and other open/free tech groups would form a Linaro-like firmware group and produce their own UEFI firmware image, as an option for OEMs. There needs to be some Free Boot alternative to Secure Boot, with certs from EFF/FSF/etc and the open source distro vendors, not just OEMs/MSFT in the firmware, and it needs to target booting from a handful of main open source distros, not just 1 commercial OS. Else, UEFI will turn Personal Computers into Windows PCs, ending the era of General Purpose computing. </soapbox> -- Liberationtech is public & archives are searchable on Google.

new PC Engines APU system in the pipeline
by Eugen Leitl 20 Sep '13

20 Sep '13

http://www.pcengines.ch/apu.htm apu platform The PC Engines apu system board is a big step up in performance and capacity from the popular ALIX series. Applications: Routers, firewalls, VOIP, dedicated servers, special purpose network plumbing, education tools... CPU: AMD G series T40N or T40E APU, 1 GHz dual core (Bobcat core) with 64 bit support, 32K data + 32K instruction + 512KB L2 cache per core DRAM: 2 GB DDR3-1066 DRAM Storage: Boot from SD card (connected through USB), external USB or m-SATA SSD. 1 SATA data + power connector. Power: About 6 to 12W of 12V DC power depending on CPU load. Expansion: 2 miniPCI express (one with SIM socket for 3G modem), LPC bus, GPIO header, I2C bus, COM2 (3.3V RXD/TXD). Connectivity: 3 Gigabit Ethernet (Realtek RTL8111E), 1 DB9 serial port (console). Firmware: CoreBoot open source system BIOS with support for iPXE and USB boot. Form factor: 6"x6" (152.4 x 152.4 mm), fits in our case1d2*u enclosures. Cooling: Conductive cooling from the CPU and south bridge to the enclosure using a 3 mm alu heat spreader. Please contact us for advice if you want to integrate this board in your own enclosure. Status: Prototypes alive and well. Pilot run / customer samples planned for fall 2013. Production expected for early 2014. OEM options: 4 GB DDR3 DRAM, various build options, different CPU speed grades. Roadmap: We will upgrade to the newer AMD Kabini / Jaguar core based SOCs, up to 2 GHz quad core (Opteron X1150), up to 4 GB ECC DRAM.

Hi David, Hi Christian, thank you for your quick response. If there is actually no active effort to support i.MX6, I’m interested in leading that project. But I cannot start before the end of the year because I have to wait for our hardware and to bring-up the board first with u-boot. Another point is to think about hardware donation. Wolfgang Von: coreboot-bounces(a)coreboot.org [mailto:coreboot-bounces@coreboot.org] Im Auftrag von David Hendricks Gesendet: Mittwoch, 18. September 2013 00:22 An: Wolfgang Kamp - datakamp Cc: coreboot(a)coreboot.org Betreff: Re: [coreboot] Freescale i.MX6 Hi Wolfgang, I do not know of any active efforts to support i.MX6 in coreboot. However, if you are interested in leading the porting effort then we can help. I think that ARM-specific portions will be simple. The hard parts are DRAM and peripheral init. If we can help you boot to the point where UART works, will you feel comfortable doing the remaining work? As far as I know, the focus of ARM development in coreboot is on Exynos5 (Cortex-A15). We are currently booting Exynos5250 and Exynos5420 systems. TI AM335X (Cortex-A8) support is still somewhat active, but is a side-project. We can initialize the CPU and get serial console output so future development will be much easier.

crossgcc build fails
by Marcello Stanisci 19 Sep '13

Hi, I'm trying to compile the cross compiler with version 1.22 of coreboot cross toolchain builder. I just did: $ make crossgcc the i386-elf part worked fine but the armv7a-eabi part fails when tries to compile GCC 4.8.1, giving the following error message: Building GCC 4.8.1 ... failed make[1]: *** [build-without-gdb] Error 1 make: *** [crossgcc] Error 2 I'm doing this on Debian 6 (squeeze).. help..

Do you of anyway to get this? You can do a git bisect, but going back that far in history can be difficult (toolchain and architecture changes). You should just keep drilling down to why it fails. You don't have to understand too much to dissect down to the failure point. Then we can look at changes in that area and figure out why. Regards, Marc -- http://se-eng.com
