[U-Boot] Updating u-boot through tftp
Hi, I'm running u-boot on TI's davinci DM365, I'm trying to update the u-boot from the u-boot, using these commands:
tftp 0x80700000 u-boot-1.3.4_ipnc_dm36x_xxx.bin nand erase 0x2C000 0x20000 nand write 0x80700000 0x2C000 0x20000
but when i try to run the erase command, i'm getting this error:
DM365 EVM :>nand erase 0x2c000 0x20000 NAND erase: device 0 offset 0x2c000, size 0x20000 NAND 256MiB 3,3V 8-bit: MTD Erase failure: -22
How can i do it? is this part locked? Thanks, Alex

Is this small page or large page NAND? If it's large page, that's not block-aligned.
Try defining CONFIG_MTD_DEBUG and CONFIG_MTD_DEBUG_VERBOSE. The latter is a value between 0 and 3, depending on how much output you want -- 0 should be sufficient for getting a basic reason for erase failure (which in U-Boot should probably be a simple printf rather than debug output).
