2.3.1 CRC Fails for Range CRC When End Address is the Last Word Address of a Flash Section

If the boot read lock is enabled, the range CRC cannot end on the last address of the application section. If the application table read lock is enabled, the range CRC cannot end on the last address before the application table.

Workaround

Ensure that the end address used in Range CRC does not end at the last address before a section with read lock is enabled. Instead, use the dedicated CRC commands for complete application sections.
