Re: [coreboot] No VGA output on e350m1 after flashing. what to do?

by Reiner Luett

Hi! On 30.06.2013 19:28, Christian Weinz wrote: > Maybe I didn't include the VGA option in the make menuconfig process. > How can I solve this problem? You need to add the VGA Option ROM (VGA BIOS -> Add VGA BIOS image). I've extracted it from the UEFI, but you also could use these: http://www.coreboot.org/index.php?title=ASRock_E350M1&oldid=11114 at the end of the page or you also may be able to use the default AMD fam14 (Persimmon) vbios. You will need to agree to the click through: http://wwwd.amd.com/support/vbioslic.nsf/userverify?openform http://www.coreboot.org/AMD_DB-FT1_PERSIMMON It's a pity, that bios_extract didn't work for now. You could use the AMI Aptio EFI MMTool with wine: http://win-lite.de/benutzer/fernando/BIOS-Tools/AMI_Aptio_EFI_MMTool_v4.50.… You need to extract OntarioEFIVbios with PCI ID 1002,9802 as Option ROM.

Re: [coreboot] On Intel Boot Guard

by Alexander Couzens

Hi Iru, we aren't still sure which boards use Intel Boot Guard and which doesn't use it. But we expect most board use it, because it's "recommended" by intel - as we dont recommend it. Also there isn't yet a test script for Intel Boot Guard. Can you post a link to that forum post? I would like to look into a x240 flash image. If you have such board it would be nice if you can send me a copy of the flash image via private mail.

Porting Libreboot to the C201 Chromebook (veyron_speedy)

by Paul Kocialkowski

Over the past week or so, I've been working to get Libreboot running on the latest ARM Chromebook: the C201, manufactured by Asus (codename veyron_speedy). The laptop is running with a RK3288 SoC and ships with Google's version of Coreboot preinstalled. It should require no proprietary code nor any proprietary firmware load or microcode update to boot, thus it would be a good fit for Libreboot, as a fully free distribution of Coreboot. In addition to that, the device's embedded controller (that handles aspects of power management as well as the keyboard and a few other things) is a microcontroller that is also running free software: the free embedded controller firmware from Google. Aside from that, it has a soldered Wi-Fi/bluetooth BCM4354 chip (cannot be removed) that has a free driver but requires to load a proprietary firmware on the chip. However, it is easy to work around that issue and not use that chip at all, e.g. using an ath9k_htc dongle on one of the two USB ports. The GPU is a Mali T764, on which Luc has been doing some early work to have free software support for it. It is uncertain[0] how long it will take to have an usable free replacement for it, but now that there is that hardware available, free graphics for Mali T GPUs would mean having a recent laptop running fully free software, down to the firmware level, without losing any major hardware feature, something that has hardly ever been achieved yet. Thus, I believe it is of the utmost importance to back Luc up on this, even if big players like ARM are trying hard to make Lima not happen and to make it difficult for Luc to keep going. Another aspect that I still have to look at in-depth is the ability to use hardware video encoding/decoding. The RK3288 has an auxiliary processor for that task, but it is unclear whether it can be used with free software or not, though the first indications that I've gathered are positive. At this point, I've been able to boot up Debian on the device, and the xfce4 interface is quite usable. It even runs big programs like Iceweasel/Firefox and LibreOffice without inconveniences. However, it cannot run desktop environments that depend on GL acceleration, such as gnome-shell, which is a shame since those would be a good fit for it. The CPU is simply too slow for offering a decent experience with software rendering (llvmpipe). Overall, I truly hope this device creates an incentive to free the last remaining parts that can only work with proprietary software to this day. Its potential would be huge, especially since it's a good fit for travellers. With the security model inherited from Chromium OS, this would be one of the safest laptops to be used by journalists or activists. If Tails was to be ported to it, it would become easy to have a secure and anonymous setup. I have successfully fixed and compiled Coreboot and all the necessary bits and pieces for the C201, so I'll be spending the next few days sending patches, discussing how to integrate it to Libreboot and getting the actual work done. I also plan on documenting all my findings (especially things like how to access UART, how to remove the SPI flash's write protect, how to reflash it externally, etc) on my coding blog, for now. Cheers!

coreboot ported to the ASUS KGPE-D16 (Libreboot: blobless, fully functional!)

by Timothy Pearson

All, I have successfully ported coreboot to the relatively modern ASUS KGPE-D16 server board (dual AMD socket G34, 16 DDR3 DIMMs, https://www.asus.com/us/Commercial_Servers_Workstations/KGPED16/)! This port uses native Family 10h initialization (_not_ AGESA or CIMX). The Libreboot folks will be interested to know that this board can run blob-free and still retain full functionality! Port specifications: CPU: Dual AMD G34 Magny-Cours (Family 10h) RAM: 16 DDR3 DIMM slots with ECC support (tested with x4 4G DDR3-1333 unbuffered DIMMs) Peripherals: PCIe slots: all functional PCI slot: functional RS-232: functional PS/2: expected to function, not tested (on SuperIO) ASpeed VGA device: functional (text mode, see below) IEEE1394: functional On-board USB: functional On-board NICs: functional ASUS PIKE SAS controller: functional PCIe ROMs: functional Power management: DDR3 voltage set: functional ACPI/APIC: functional Suspend/resume: broken Other: cbmem console: partial support (log truncated) cbmem timestamps: functional nvram: functional BIOS recovery jumper: functional ASpeed VGA: The ASpeed VGA device initialises in text mode via its (new) coreboot driver, however this initialisation is incomplete, leading to distorted but quite usable VGA output. When Linux boots and engages the graphical framebuffer all distortion disappears. This port was not trivial. Almost every device used was broken and required debugging/repair, with the notable exception of the SuperIO chip. The AMD DDR3 controller was severely broken to the point where large rewrites were needed in order to bring it in line with the BKDG. Even after the various component drivers were repaired Due to the labor-intensive nature of the port and the extensive changes throughout the entire source tree, it is not economically feasible to merge this port upstream at this time (I estimate upward of 30 independent patches would be required just to get the board booting!). Raptor Engineering will, however, be continuing to maintain this port internally, and I am currently looking into adding native Family 15h support on top of this internal tree. Additionally, while it was not a priority for the initial port, I will be attempting to enable suspend/resume functionality as I have time. If there is sufficient interest from the community in adding this board to coreboot I would consider merging the changes in exchange for a one-time contract payment in the vicinity of $35,000 USD. When considering this offer please bear in mind that this is a fully functional blobless board with a wide range of peripherals and expansion options available, and that once these large changes are merged I will continue to enhance coreboot functionality as before (e.g. with the KFSN4-DRE and the T400). I would also be willing to add this board to the test stand as the only fully supported 4-way Opteron board (socket G34 Magny-Cours CPUs contain two separate CPUs in one package, making this 2-socket board a 4-way system from a HyperTransport perspective). Please let me know if you have any questions! -- Timothy Pearson Raptor Engineering +1 (415) 727-8645 http://www.raptorengineeringinc.com

by coreboot conference

Dear vendors, developers and interested parties, on behalf of the Federal Office for Information Security (BSI) Germany I would like to invite you to the coreboot conference and developer meeting on October 9-11 2015 in Bonn, Germany. This conference and developer meeting is geared towards manufacturers of hardware (processors, chipsets, mainboards and servers/ laptops/ tablets/ desktops/ appliances) as well as developers of firmware with an interest in coreboot and the possibilities it offers. The Federal Office for Information Security (BSI) in Germany will host the conference in Bonn, Germany. As the national cyber security authority, the goal of the BSI is to promote IT security in Germany. For this reason, the BSI has funded coreboot development in the past for security reasons. The date of the coreboot conference is Friday October 9 to Sunday October 11, 2015. This is scheduled directly after Embedded Linux Conference Europe to make travel arrangements easier for people attending both events. If your main interest is forging business relationships and/or strategic coordination and you want to skip the technical workshops, Friday (and possibly Saturday) will be the outreach day of talks, presentations and discussions. If your main interest is doing development, you can use the separate developer room next to the during all three days of the conference. Call for presentations: We are looking for interesting talks/presentations about coreboot related topics for the first (and possibly second) day of the conference. Please note that those presentations are not intended to be advertisements or company portfolio presentations. Expected duration is between 10 and 45 minutes. Submission: Please send the title, a brief summary, the expected duration and name/organization of the speaker to <coreboot-conference(a)bsi.bund.de> until September 21. We will notify you of acceptance until September 28. If you want us to make sure the slides work fine with the projector at the venue, please submit your final slides in pdf form before Ocober 7. Call for discussion topics and development suggestions: We hope to stimulate discussion and foster new ideas as well as explore ways to improve code, development and deployment. The format for this will be a few minutes (1-5) of presenting your idea/topic followed by discussing it with the audience for approximately 5-20 minutes. While there is no formal deadline for submission, we'd appreciate a submission to <coreboot-conference(a)bsi.bund.de> before October 2 to be able to list the topic on the agenda to allow others to think about the topic in advance. Call for profiles: This is the chance to tell others what you're doing, what you can offer and in what area you'd like to collaborate. If desired, we can attempt to distribute your profile to other conference participants before the conference. Please submit such profiles before September 30 to <coreboot-conference(a)bsi.bund.de> . Call for developers: If you want to do development all day, every day, just come and do it. We have power, networking and some spare hardware (please tell us in advance if you need something on site, we might have it in our lab). Travel information: If you wonder about how to reach Bonn, there are three options available by plane: The closest is Cologne Airport (CGN), 30 minutes by bus to Bonn main station. Next is Dusseldorf Airport (DUS), 1 hour by train to Bonn main station. The airport with most international destinations is Frankfurt Airport (FRA), 1 hour by train to Bonn main station. There’s the option to travel by train as well. Bonn is reachable by high-speed train (ICE), and other high-speed train stations are reasonably close (30 minutes). Conference location: Wissenschaftszentrum Bonn Ahrstrasse 45 53175 Bonn GERMANY Getting there (German only) http://www.stifterverband.info/veranstaltungen/wissenschaftszentrum_bonn/an… An English version of the directions will be available at http://coreboot.org/coreboot_conference_Bonn_2015 Accommodation: Accommodation is not centrally organized, but if desired we can point you to websites listing hotel contact information and/or booking services as well as the local tourist information office.

Output debug log to HSUART1

by Cao Duc Quan

Dear all, I am working on custom board base on BYT-I E3825. The PCBA has two serial debug port connected to HSUART1 and HSUART2. I wonder if there is anyone enable the debug log to HSUART1 ? My configuration for coreboot base on MinnowMax board which uses legacy console so I do not get any output from coreboot (both romstage and ramstage). I think HSUART1 is connected to PCI bus so we should use uart8250mem.c ? I have tried it but no luck. Any help or guideline is highly appreciated. Thanks a lot, -- Quan Cao 0976574864
