If both primary and secondary boot fails, then after a timeout, the device will go thru a reset and attempt to reboot with the same primary/secondary boot modes. This process would go on indefinitely.

hi James,

Thanks for your support.

i need to clear one more point. For the first time when my board is fresh, no boot image is available in primary boot and secondary boot, then will it go in USB boot mode automatically or else which mode will be use for flashing the board.

Sounds like you want to be able to update a fresh board with USB DFU. You would have to designate either the primary or secondary boot modes as USB DFU (or be able to switch the boot mode signals to designate USB DFU). The processor does not default to any boot mode, it only boots what is designated in the BOOTMODE signals.

James
