Hello,
Im having a trouble with my Nand Flash device wich is a 512MiB Micron with 4GB capacity.
I get io error -5 for any erase/write operation on it like this :
barebox@Phytec phyCard-i.MX27:/ update -t barebox -d nand
phy0: Link is up - 100/Full
host 192.168.0.2 is alive
erasing partition /dev/nand0.barebox.bb
erase: I/O error
flashing barebox.bin to /dev/nand0.barebox.bb
TFTP from server 192.168.0.2 ('barebox.bin' -> '/dev/nand0.barebox.bb')
write: I/O error
tftp failed: error -5
And here is the device init at the boot runtime:
NAND device: Manufacturer ID: 0x2c, Chip ID: 0xac (Micron NAND 512MiB 1,8V 8-bi)

So it seems tge device is detect and bbt are correctly calculated...
Any idea of what could be the problem ?
