If your only way to flash the flash is via a program, or something embedded in the lenovo bios, stop now, or stockpile 20 or 30 of these laptops, because you're going to create some bricks along the way. ron

No way. You will need to use serial port. Just plug the header to mainboard and use some USB 2 serial from other computer (together with null modem cable) if you need more info please let me know. >> Is it Richland or Trinity?

It looks some people can send me some money and I could buy the richland to see if it workks... but this could happen somewhere in March. >>> Can you send me a link to a known-good image that you use?

Default kernel configuration will not output anything on usbdebug. Now that you know the correct physical USB port, have the phone powered on and connected, run 'cat /dev/ttyGS0' and then boot the chromebox with the coreboot image with usbdebug feature enabled. On this boot, what do you get for dmesg output on the phone side? Just send the complete log or put it available for download without separate request. If still nothing interesting appears, you could try coreboot with spkmodem console and possibly POST display card, but I do not know how to connect those on chromebox. And.. last but not least, the instructions you followed, did they have a step with 'make crossgcc'? Kyösti

Lenovo Thinkpad T61
by Roberto A. Foglietta 31 Jan '14

Hi, I check the list of supported motherboards and laptops but I did not found in them the Lenovo Thinkpad T61 I have one under my hands but I saw that EC could cause a lot fo trouble but few others Thinkpad are supported. I followed this guide http://www.coreboot.org/Motherboard_Porting_Guide but obviously EC does not allow the flashrom to dump the rom but the rom is available on lenovo website and it exist a proprietary flash utility by the vendor. All logs are available, just ask me for them. I did not followed this other guide http://www.coreboot.org/Board:lenovo/x60/Installation because I would like to understand the magnitude of probability to brick the laptop before. Thanks, raf

But I am too close to see if some obvious details from my instructions were missing. This is more easily solved if you come to discuss on #coreboot. You should then write a tutorial for our wiki or at least reply here with the steps were you went wrong the first time. Kyösti

stylus support on x60 tablet
by The Gluglug 31 Jan '14

31 Jan '14

Hi, I'm gathering information as per request on behalf of an existing x60t user (he does not yet have coreboot). He wonders, if work is being done to support the stylus function on an x60 tablet machine. If no work is currently being done (and noone is interested) he wonders who would be able to implement it regardless (he is happy to pay for this to be done). The wiki mentions that this is "WIP" but does not seem to link to any relevant information. It does link here http://forum.bongofish.co.uk/index.php?topic=2307.0 and here http://www.thinkwiki.org/wiki/Wacom_Serial_Tablet_PC_Stylus which seems to contain some information. The first link seems to show some datasheets/schematics. Who should I contact regarding further development?
