Shahrom,

Have you done any testing with your driver with the NAND part on the
2430SDP-v5.0 boards?

Using your driver, the chip is probed/reported correctly (see boot
excerpt below), but the I can't seem to use the MTD tools to work with
any of the partitions?

For example, flash_info gives: 'Device /dev/mtdX has 0 erase regions'
for each partition on the NAND device.  And trying a flash_erase gives
'File open error'.

Any ideas?

Kevin
