itnerested in the solution... me, for instance.

Engineering is the art of making what you want from things you can get.

Hello,
I've got an interest problem with BF532 boot. BF booted parallel with
an emulated flash. both modes (8 or 16 bit) have same problem.
I logged the BF bus, and the boot rom is running, but some differences
have been found:
-in bootmode 01 (parallel async flash mode) boot rom reads the first
byte /word to determine the flash width. After a little wait founds,
that is normal. As ADI's engineering (EE-240) note shows , the reading
address is following in 8 bit mode: 0,1,2,3,4,5,6,7,8,9, and in 16 bit
mode : 0,0,1,1,2,2,3,3,4,4. On my board, BF addressing have some
difference: 0,0,1,2,3,4,5,6,7,8 in 8 bit mode, and 0,0,0,1,1,2,2,3,3,4
in 16 bit mode. I think this causing error in boot variables within
boot rom's data (for example, target address, byte count, and flags).
Question is what kind of problems may resulting this error ?

Jozsef
