The timeout check is not correct in the current code. I had submitted a patch to Wolfgang on July 2nd, 2005. I do not know if/when he will apply it. The patch is available via:

Try if it solves your issue...
Best regards, Tolunay

Hi All, First, my thanks to the CFI developers -- great job!
With the erase and cp commands, the CFI flash driver seems just fine. However, when I execute saveenv (env is in flash), I observe "Flash not Erased".
I'm using AMDLV065D on a Nios-II board with the latest cfi_flash.c (rev 1.18). In routine flash_write_cfiword (cfi_flash.c, line 1146), flag == 0, indicating that the flash is not "(sufficiently) erased":
flag = ((cptr.cp[0] & cword.c) == cword.c);Adding a delay of about 500 msec corrects the problem, and I was able to trace the bits changing (eventually) to 0xff with some hack code.
This is the first time I've worked with the CFI code, so I'm looking for some guidance from someone familiar with the code on how to track down the problem/potential solution & where I should focus my attention.
Thanks, --Scott
