Hi Iru Cai, take a look at this http://review.coreboot.org/#/c/11765/ change. But beware there can be issues with that port.

coreboot on Lenovo T420
by Iru Cai 03 Oct '15

03 Oct '15

Hi, I installed coreboot on my Lenovo ThinkPad T420 laptop today, and I'd like to share some experience and hope some one can solve some issues on it. First, I built the T420s port and flashed it to the T420 laptop. Fortunately, the laptop could be brought up and boot to Linux. However, several USB ports didn't function properly(except the one for EHCI debug) because of the difference between T420s and T420 model. Now I've checked and used the code from the result generated from autoport, and all the USB ports work fine. However, the devicetree.cb file generated from autoport does not work properly. I use GRUB payload with native graphic init. When I use the T420s devicetree.cb, it works fine, but with the autoport devicetree.cb, only the backlight is on and nothing displays. At last I built a kernel for GRUB payload, and the kernel handled the display properly, then I reflashed another ROM with flashrom to unbrick my laptop. So can some one give me some instruction on devicetree.cb file? And another thing, how can I submit the code to the coreboot repository? Is symlinks to another source files allowed in the source tree? Iru Cai

coreboot conference 2015 invitation
by coreboot conference 02 Oct '15

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. We also have a small allotment of rooms close to the venue reserved for conference participants, just ask us. Spare time activities: If there is enough interest, it might be possible to get a tour of the former top secret bunker of the German Federal Government on Saturday evening. More info at http://regbu.de/Fremdsprachen/GB1.html Besides that, Bonn and Cologne have lots of tourist attractions Food and drinks: More info will be posted to http://coreboot.org/coreboot_conference_Bonn_2015 shortly. Date and time: October 9-11 2015 Friday: 9:00-19:00 Saturday: 9:00-16:00 Sunday: 9:00-19:00 To enable us to estimate the number of attendees (for catering etc.), please notify us ASAP whether you will attend the conference at <coreboot-conference(a)bsi.bund.de>. Thank you!

Has anyone ported coreboot to ThinkPad T420?
by Iru Cai 30 Sep '15

30 Sep '15

Hi, community I found Lenovo X220, T420s and T520 have coreboot support, but T420 is not in the support list. I used the autoport tool in coreboot, and found some differences(e.g. GPIO) between T420 and the supported models. I think it should be easy to port it. I've just disassembled a Lenovo ThinkPad T420, and found a Winbond 25Q64CV flash after I moved the mainboard out. However, I couldn't read it with my flash programmer. I don't know if the flash can be read if I try another programmer or SOIC-8 clip. Iru
