[commit] r1600 - trunk

21 Sep '12

Author: stefanct Date: Fri Sep 21 14:46:56 2012 New Revision: 1600 URL: http://flashrom.org/trac/flashrom/changeset/1600 Log: Add spi_block_erase_62. This is used by the AT25F series (only?), but is generic enough to reside in spi25.c. The only currently supported chip is the AT25F512B. Other members of that series need some additional infrastructure code, hence this patch adds the erase function to the AT25F512B only.

TODO: Check if SPI is active. great, that means carl-daniel's code is working as expected to this point. but there is much more work to do before accessing the flash chip will work and he is constantly busy (with tiny breaks in between :) so please don't expect any further progress soon (and be happy in case my prediction turns out to be wrong). -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Hi Philipp Matthias, I noticed that you sent this log only to me and not to the mailing list. That's why I'm fullquoting it now. An updated patch will follow shortly.

Hi! Thanks for the log. It seems like your board uses a superio chip that is not supported by flashrom yet. Carl-Daniel is working on a patch for it, but it does (or should) only detect that chip at the moment - it does not enable read or write access yet. Please do not expect flashrom to work on that board soon, sorry. If you want to help us add support for that board please get the source of flashrom from http://flashrom.org/Downloads#Installation_from_source apply the patch below, compile it and reply with a verbose log again. If you need help with that just ask or visit our IRC channel (#flashrom on chat.freenode.net). the current patch: http://patchwork.coreboot.org/patch/3713/ -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
