[PATCH] Move erase checks out of chip drivers
by Carl-Daniel Hailfinger 26 Jun '11

26 Jun '11

Erase functions are no longer called from chip drivers and thus their internal erase verification can be moved to generic code. This also makes it easier to skip the verify step if desired.

[PATCH] Use strlen for const strings
by Carl-Daniel Hailfinger 26 Jun '11

26 Jun '11

Replace sizeof("string")-1 with strlen("string") We want to avoid calls to strlen at runtime if the string is already known at compile time. Turns out that gcc and clang will recognize constant strings and compute the strlen result already at compile time, so trickery with sizeof only reduces readability but does not improve the code.

[PATCH] Flush stdout after each message
by Ed Swierk 19 Jun '11

19 Jun '11

Currently messages like "Writing flash chip..." that don't end with a newline are buffered until the operation is complete, unless the particular write function generates status output in the meantime. Flushing stdout after each message ensures that the message appears immediately.

Success flashing Supermicro X7SPA-HF
by Jochen Schulz 18 Jun '11

18 Jun '11

Hi, I just wanted to say thanks and report that I just successfully flashed the BIOS of my brand-new mainboard Supermicro X7SPA-HF¹ using flashrom. After wasting a whole evening trying to make a 4MB BIOS image fit onto a (virtual) floppy, I stumbled upon flashrom again and, without much thought, decided to give it a try. I tried reading the current BIOS first and after that worked I flashed the file X7SPA0.526 from the current zip download. I ignored the message that erasing is untested and another one that suggested that a single block or something like that couldn't be eraed. After five minutes of waiting I became a little bit nervous, but two or three minutes later flashrom was finished and I could reboot successfully. So, thanks again, flashrom saved my day. If you need any further information for your documentation, please Cc me as I am not subscribed.

Just thought I'd send this note since the motherboard isn't listed in the wiki yet. Reading the old image from chip also worked fine. -- Jani
