The bootcounter (stored in the RAM) is not enough protected with the 4 Bytes BOOTCOUNT_MAGIC against bit errors due to short power loss or holding a system in RESET. It has been seen, that the bootcounter value has been changed due to a bit flip on a system holding in RESET, but the BOOTCOUNT_MAGIC was still valid. A bit pattern with 4000 bytes (after BOOTCOUNT_MAGIC) has been implemented, which should be enough to detect a bit error.
