Flash appears read-only?

Wed Jul 24 11:54:05 EDT 2002

 The 2.4.17 distribution that I am using did not properly support 64-bit
 flash. In order to fix this, I got the latest version of the MTD code from
 CVS and integrated that into our source tree. I modified maps/physmap.c to
 provide the partition information required for our configuration but no
 matter what I do the partitions appear to be Read-only. I can not erase or
 mount the partitions with Write enabled.

 Any ideas?
