This is really strange. Code reads:

i = strncmp(cmd, "read", 4) == 0;       /* 1 = read, 0 = write */
printf("\nNAND %s: device %d offset %u, size %u ... ",
       i ? "read" : "write", nand_curr_device, off, size);
if (i)
	ret = nand_read(nand, off, &size, (u_char *)addr);
else
	ret = nand_write(nand, off, &size, (u_char *)addr);
printf(" %d bytes %s: %s\n", size,
       i ? "read" : "written", ret ? "ERROR" : "OK");
return ret == 0 ? 0 : 1;

So it seems nand_write returned sucessfuly. Could you debug it a bit
more? Perhaps stack corruption?

Thanks,
