6 Boot Loader

The module is delivered with a pre-flashed boot loader. The bootloader memory section (8 kB) is write-protected at factory. To overwrite the write-protection, program the BOOTPROT bits[2:0] of NVM User Row with the default value of 0x7.

Customers not using the bootloader must program the BOOTPROT bits to default value to program the complete Flash of the SAMR30 device. For detailed information, refer to the boot loader manual. The related information is available in the AVR2054 Application Note.
