I’m using the MPC8540ADS bsp on a custom board.
We tested the hardware and we can access the flash, with the JTAG and
the boot loader (U-boot). The boot loader as a CFI flash driver which
work perfectly.
QNX is started from flash by the boot loader and works good, I’m using
QNX 6.3.0 SP1.
I’ve got a problem using the devf-generic with flash memory (Spansion
29GL256M).
Physical configuration is: 2 chips, CPU bus width 32 bits.
I tried the commands bellow. Did i miss something obvious or did I
choose the wrong flash chip, because CFI_MirrorBit_Workaround doesn’t
sound good ?
