Eraseblock definitions for some chips

Hi, I have the following list of erase block structures still lying around: AMIC_A29002B, { {16 * 1024, 1}, {8 * 1024, 2}, {32 * 1024, 1}, {64 * 1024, 3} } AMIC_A29002T, { {64 * 1024, 3}, {32 * 1024, 1}, {8 * 1024, 2}, {16 * 1024, 1} } EN_29F002B, { {16 * 1024, 1}, {8 * 1024, 2}, {32 * 1024, 1}, {64 * 1024, 3} } EN_29F002T, { {64 * 1024, 3}, {32 * 1024, 1}, {8 * 1024, 2}, {16 * 1024, 1} } MBM29F004BC, { {16 * 1024, 1}, {8 * 1024, 2}, {32 * 1024, 1}, {64 * 1024, 7} } MBM29F004TC, { {64 * 1024, 7}, {32 * 1024, 1}, {8 * 1024, 2}, {16 * 1024, 1} } MBM29F400BC, { {16 * 1024, 1}, {8 * 1024, 2}, {32 * 1024, 1}, {64 * 1024, 7} } MBM29F400TC, { {64 * 1024, 7}, {32 * 1024, 1}, {8 * 1024, 2}, {16 * 1024, 1} } MX_25L3205, { {4 * 1024, 1024} } MX_25L6405, { {4 * 1024, 2048} } MX_29F002B, { {16 * 1024, 1}, {8 * 1024, 2}, {32 * 1024, 1}, {64 * 1024, 3} } MX_29F002T, { {64 * 1024, 3}, {32 * 1024, 1}, {8 * 1024, 2}, {16 * 1024, 1} } No guarantees about completeness (and note that the corresponding erase functions are not part of that list), but it might be useful in case someone wants to cross-check his/her work.

Scary error message
by Fraser Hanson 23 Dec '09

23 Dec '09

Hi, I flashed my bios with flashrom tonight and got the scary warning message saying "erase failed" and "do not reboot". I haven't rebooted. As far as I can tell from using flashrom itself, everything is actually fine. The erase appears to have failed at physical address 0, which I would guess means that nothing actually happened. I had taken a dump of the original bios before starting, and "flashrom -v" now verifies that it is identical. Furthermore, a new dump of the bios matches the original dump from before I tried to write the bios. My board is an MSI K8N Neo4 Platinum. Output from my dump attempt and subsequent messing around follows. Do I have your blessing to reboot my machine? --Fraser ====================================================================== fraser@ged:/tmp/7125v1D$ sudo flashrom flashrom v0.9.1-r706 No coreboot table found.

flash erase failure
by Thao Hoang 22 Dec '09

22 Dec '09

Hi there. I'm trying to use flashrom and although the program can detect both my chipset and my flash part (which are both tested & supported), the erase routine fails. (Although I don't think it even erase since the content read after this failure was the same and the board does boot up properly.) What do you think is going on? Do you think it's something with my mainboard (per some of the discussion I have seen?) Here is what I get when I do a write.... Thanks also for all the good work! root@slax:/home/user/flashrom_folder/flashrom_unrelease# ./flashrom -f -w backup.rom flashrom v0.9.1-runknown No coreboot table found.
