Blackfin boot process problem

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 ?

regards,
Jozsef

Problem solved!

 I second Jerry&#4294967295;s question: how? Chances are that many readers here are 
itnerested in the solution... me, for instance.
