Usually, you will need your bootloader to run from NOR flash.&nbsp;The uBoot bootloader can read USB and filesystems in NAND flash. You can google uBoot and find a lot of information about it. dBug is available for download from Freescale. dBug cannot boot from USB or NAND flash so you&nbsp;have to have your kernel in NOR flash and copy to RAM.
