but when i try to run the erase command, i'm getting this error:

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).
