1. the method to copy the boot image to NAND flash using USB OTG port.

- without upload the boot image on NAND flash, and copy boot image through USB OTG.

To write/flash image to NAND, this image need first to be loaded in DDR memory. You can not directly write image from USB to NAND, you should use DDR in the middle.

When writing to NAND partition the file to be written must have previously been copied to memory.

nand write <ddr address> <partition name> <file size>

The symbol <ddr address> refers to the location in memory that a file was read into DDR memory.

You can also use USB Device Firmware Upgrade (DFU)
