HPT360/HPT370 ATA controller flash interface
by Michael Karcher 21 Feb '10

21 Feb '10

Hello flashrom developers, (obtained from reversing the vendor update tool) Supported IDs (names stolen from pci.ids, the double 372N is not my fault): 1103:0004 HPT366/368/370/370A/372/372N 1103:0005 HPT372A/372N 1103:0006 HPT302/302N Flash enable at 58L.24 (setpci syntax), set to enable flash writing Flash interface select at 70B, 1 = mmapped in ROM addr space, 0 = io mapped IO-mapped access: (BAR4)+0x90 -> DWORD Address (BAR4)+0x94 -> BYTE/WORD/DWORD data access. memmapped chip access was not shown in the tool, but the flash disable code disables the extension ROM BAR. So probably its just mmapped read/write in that area. Maximum Chip size supported by the vendor tool: 128K Regards, Michael Karcher

Recommendation for board to be used only with flashrom?
by Daniel Clark 20 Feb '10

20 Feb '10

I'm looking for a well-supported by flashrom, preferably very inexpensive board to use only as a PLCC programmer for other devices [1]. Anyone have a specific recommendation?

Re: [flashrom] [PATCH] Probe/Read tested for SST29EE020A

I believe, that committing each (un)successful report in a separated patch is a better idea, than combining them into one or more larger patches (that means some unavoidable delay). -- With best regards, Peter Lemenkov.

19 Feb '10

The following command ran successfully on an eMachines 333cs. (I checked that my.rom was the same as the original ROM file flashed to the BIOS.) flashrom -rV my.rom > flashrom.txt The smolt URL for this machine is http://www.smolts.org/client/show/pub_7982b3d7-a650-4770-8128-d385918bf9bd The file flashrom.txt is attached.
