Calibrating timer since microsleep sucks ... takes a second Setting up microsecond timing loop 788M loops per second OK, calibrated, now do the deed Trying Am29F040B, 512 KB probe_29f040b: id1 0xff, id2 0xff Trying At29C040A, 512 KB
so it's almost certainly not a 512KB, since you are reading 0xff
probe_jedec: id1 0xff, id2 0xff Trying Mx29f002, 256 KB probe_29f002: id1 0xdf, id2 0x24
0xdf, 0x24
now you could try dumping the bios without flashrom. if the first two bytes are not df,24 then you are probably doing an ID cycle, and flashrom just doesn't know this ID.
If the bytes ARE df,24, then write protection may be in effect.
Trying SST29EE020A, 256 KB probe_jedec: id1 0xdf, id2 0x24 Trying SST28SF040A, 512 KB probe_28sf040: id1 0xff, id2 0xff Trying SST39SF020A, 256 KB probe_jedec: id1 0xdf, id2 0x24 Trying SST39VF020, 256 KB probe_jedec: id1 0xdf, id2 0x24 Trying SST49LF040, 512 KB probe_jedec: id1 0xff, id2 0xff Trying SST49LF080A, 1024 KB probe_jedec: id1 0xff, id2 0xff Trying SST49LF002A/B, 256 KB probe_jedec: id1 0xdf, id2 0x24 Trying SST49LF003A/B, 384 KB probe_jedec: id1 0x47, id2 0x97
interesting. based on this, I'm guessing a 256kB part. Let us know if you can get the #.
