Can you try the following two patches to see if they solve your problem http://review.coreboot.org/11636 Don't use fileno() to get file size http://review.coreboot.org/11637 fmd: Use _fileno() on MINGW Also, if that doesn't work try to replace the MINGW check with something like #if defined (_WIN64) || defined (__CYGWIN64__) instead.

unbricking an Acer CB5
by Holger Brunn 14 Sep '15

14 Sep '15

Dear readers, I played with compiling my own coreboot image for my Acer CB5 [1] and failed miserably - the bios is messed up and the device won't boot any more. Now I'm busy following some guides to undo the damage [2], [3] by flashing the original bios again, but given I'm quite clueless about hardware, I'd like to ask you for advice about how to proceed: I ordered a Raspberry PI, some connector cables [4], and then I probably need a clip to connect the chip [5]. My question to you is how to locate the chip? The mainboard looks like that: http://opensource.holgerbrunn.net/debian-on-acer-cb5/images/DSC01629.JPG and the only chip that looks like those in the examples is U37 in the lower right. Is there any way to know beforehand if it's the correct one? And then when connecting the pins, can I look up somewhere what the correct assignment is or is this trial and error? I can't read what is printed on it, but if relevant, I'll get a magnifying glass to post the text. Thank you a lot in advance, and be sure that I won't come back whining if anything goes wrong and I fry the chip following your advice - that's entirely my fault then. I'll log the process on the above website if successful so that the next person messing this up won't have to bother you.

I overlooked stack usage while wondering if those MTRRs really need to be backed up in SPI in the first place. http://review.coreboot.org/#/c/11633/ Thanks, Kyösti

Building the similar ASRock E350M1 with the modification proposed by Julius, building stops with the error below. ``` $ make […] CC northbridge/amd/agesa/oem_s3.ramstage.o src/northbridge/amd/agesa/oem_s3.c: In function 'OemS3Save': src/northbridge/amd/agesa/oem_s3.c:118:14: error: stack usage might be 4144 bytes [-Werror=stack-usage=] AGESA_STATUS OemS3Save(void *vS3SaveParams) ^ ``` Thanks, Paul
