Somebody in the thread at some point said:
| Hi
|    i find a way to debug my code. if the nand_read work there only one
| led on,
| if there is something wrong the two led will blink.
| now it is tow led blink.
|    it something wrong here:
|    if ((start_addr & NAND_BLOCK_MASK) || (size & NAND_BLOCK_MASK))
|                return -1;      /* invalid alignment */
|
| i use
| "dfu-util -a 0 -R -D ./led_on
| nand write.e 0x32000000 0 0x1000" download a image to the nand.
|
| then when i want read this image from nand,
| is it the start_addr is 0x32000000?

What is size and NAND_BLOCK_MASK at this time?

For serial console debug, it's still a question about how to write to
the serial device?
