Brad,
In the recent port of Cogent CSB472 which uses an Intel 28F640J3 (16bit
bus, 16bit chip), I noticed that after "cp" command finished the flash is
not properly returned to read array mode.
To work around I issue a protect off 1:0 for now (I use real sector
protection).
I use the exact same driver which uses 2x Intel 28F128J3 (32bit bus, 16bit
chip) Cogent CSB272, I have no such problem. I am using buffered writes in
either case...
Since I only have one CSB472 and it is put to service in a rush, I did not
have opportunity to debug the problem.
Did you or anyone else experienced the same issue?
Best regards,
Tolunay
