Ahh et finaly i found the problems .
Problem 1 : In the original external storage sample have a syntaxys problem in the bus init
parameter setting . After the address mask found a extra “,” . If remove these
the parameter is become working .
problem 2 : The businit (i dont know why ) not accept the hexadecimal settings only decimal .
problem 3 : In the sample have 0x07FFFFFF mask setting . The cpu accept the but not using that .
If use the corret 0x03FFFFFF that working fine on 2687 . If use 0x07FFFFFF working only
width WMP100 .
I tested on both type . (WMP100 and 2687H)
Now is working allbus is fine . :smiley: :smiley: :smiley: :smiley:
