sd_mbr_command_copy_bl_t

This command copies a new BootLoader.

The MBR assumes that either MBR_BOOTLOADER_ADDR or MBR_UICR_BOOTLOADER_ADDR is set to the address where the bootloader will be copied. If both addresses are set, the MBR will prioritize MBR_BOOTLOADER_ADDR .

The bootloader destination is erased by this function. If (destination+bl_len) is in the middle of a flash page, that whole flash page will be erased.

This command requires that MBR_PARAM_PAGE_ADDR or MBR_UICR_PARAM_PAGE_ADDR is set, see sd_mbr_command .

This command will use the flash protect peripheral (BPROT or ACL) to protect the flash that is not intended to be written.

On success, this function will not return. It will start the new bootloader from reset-vector as normal.

Return values

NRF_ERROR_INTERNAL	indicates an internal error that should not happen.
NRF_ERROR_FORBIDDEN	if the bootloader address is not set.
NRF_ERROR_INVALID_LENGTH	if parameters attempts to read or write outside flash area.
NRF_ERROR_NO_MEM	No MBR parameter page is provided. See sd_mbr_command .
