We have a MIP405-1 and a MIP405-3 from MPL (http://www.mpl.ch/t2720.html). When we try to format an Am29F040B flash chip in the Multi-Purpose Socket, it works just fine on the MIP405-1 (which has a 266 MHz PPC405GP) but fails on the MIP405-3 (which has a 400 MHz PPC405GPr).
When we try to format on the PPC405GPr we get this:
(devf t3::amd_v2wordwrite:128) program verify error
between 0x8012fff2 and 0x8012fff8
memory = 0x8012fff7, offset = 0x2fff2, left = 0, size = 6, bus_width = 1
flashctl: format failed
We tried this in two MIP405-3 cards, with the same result.
If we put a preformatted and initialized Am29F040B in the Multi-Purpose Socket of the MIP405-3 it works fine until we try to write to it, at which point it becomes corrupted.
We’re running QNX 6.3.0SP2.
