Your flash part[s] are almost certainly write-protected, or part of them is. Get the data-sheet for them and find what combination to write to them to un-protect them and try again. For the parts I'm using (micron MT28F128J3) writing 0x00600060 followed by 0x00d000d0 to the part does the trick. -michael _______________________________________________ Linuxppc-embedded mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-embedded
