Once I reboot the > device, my changes are gone. Please check using the /dev/mtd0 device directly to see whether your writes are 'taking'. What 'map' driver are you using? I found that it didn't work for me on the iPAQ because I wasn't enabling the Vpp voltage during write cycles. Is this necessary on your targer? Other than that, poke the author and/or look at the code yourself to see what's happening. What interleave/buswidth are you using? Note to self: Must produce a proper bug report for Nico for the current cfi_cmdset_0001 code, does doesn't work for me on 1x16 devices. -- dwmw2 To unsubscribe, send "unsubscribe mtd" to majordomo@infradead.org
