ASUS OPLX-M results (no flash device found)
by Ville Skyttä 17 Feb '12

17 Feb '12

Hello, I tried out flashrom on a ASUS OPLX-M motherboard, and it didn't find a flash device. I found some info by googling (that I cannot verify) that the OPLX-M would be an OEM (or something) version of the ASUS MEL-M; I suppose this particular board originally came with a Fujitsu/Siemens PC. http://support.asus.com/download/download.aspx?modelname=MEL-M&SLanguage=en…

Author: stefanct Date: Fri Feb 17 15:51:04 2012 New Revision: 1500 URL: http://flashrom.org/trac/flashrom/changeset/1500 Log: Add support for SFDP (JESD216). Similar to modules using the opaque programmer framework (e.g. ICH Hardware Sequencing) this uses a template struct flashchip element in flashchips.c with a special probe function that fills the obtained values into that struct. This allows yet unknown SPI chips to be supported (read, erase, write) almost as if it was already added to flashchips.c.
