Detailed Description

This command copies a new BootLoader. With this command, destination of BootLoader is always the address written in NRF_UICR->BOOTADDR.

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 function will use PROTENSET 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.

NRF_ERROR_FORBIDDEN	if NRF_UICR->BOOTADDR is not set.
NRF_ERROR_INVALID_LENGTH	if parameters attempts to read or write outside flash area.
