some questions about flashrom in windows edition
by zhou 09 Aug '09

09 Aug '09

hello, my honor! I am very interested in the program of flashrom,especially of the edition in windows,now I had worked on it for a few months,but there is some questions I couldn't understand, I wonder if you could offer me some help.The questions are showed as below: * 1,what's the use of the source code "Board_enable.c"? It looks so strange to me that I hardly understand? How I get something helpful? * 2,In order to modify the program under GNU,how can I test it? And how to debug it in details in windows? Is there any software ? * 3,As it is a complex program, where can I find out all the datasheets suitable? Are they free? I am looking forward your answers and please reply as soon as possible . My best wishes! james

[PATCH] Clean up before Windows support merge
by Carl-Daniel Hailfinger 09 Aug '09

09 Aug '09

Stefan pointed out a few issues with the current code which have to be worked around in the Windows support patch. Fix them. Remove unnecessary #include files. Serprog compilation is now controlled by a Makefile variable. Replace munmap with physunmap where appropriate.

ICH6-ICH10 flash decode debug, IDSEL=0 hardcode
by Carl-Daniel Hailfinger 06 Aug '09

06 Aug '09

Add ICH6,ICH7,ICH8,ICH9,ICH10 FWH IDSEL settings and flash decode settings to the debug output. This can help debug cases where the BIOS does not set up a correct flash decode for the given flash size. The Intel docs state that the decode applies to FWH and SPI flash. Hardcode IDSEL=0 for the top 8 MB for now.

SPIPGM bug for SST25*
by Carl-Daniel Hailfinger 05 Aug '09

05 Aug '09

Hi RayeR, I found that SST25 flash only allows one-byte write and no page write. But it uses the normal page write opcode. To fix this, SPI_FLASH_PAGE_SIZE must be 1 instead of 256 for SST25 family. Regards, Carl-Daniel
