Flashrom (from svn) would try to detect the Am29F040 using addresses
0x0555, 0x02AA, 0x0555 - which is not according to the datasheet.
The Problem is
the Am29F040B uses 0x2AA variant, but the Am29F040 uses
0x2AAA. What AMD/Spansion did was change the command addresses without
Do we have
a user with a Am29F040B that works with the 2AA variant? In
that case have him/her test with the 2AAA variant. It is quite likely
that the 2AAA variant works on all chips (the higher bits being ignored)
by the 2AA chip.
