Changing the -e to a -v would give you a list of the files and their size ZIPed and UNZIPed along with an indication of the crunching method used, the file creation dates and the results of a circular redundancy check (CRC) for errors.
The SAM L22 series delivers advanced security features with 256-bit AES, cyclic redundancy check (CRC), true random number generator, Flash protection and tamper detection to ensure information is securely stored, delivered and accessible.
In addition, a hardware Cyclic Redundancy Check (CRC) engine allows safety verification of the validity of the contents of the Flash memory, as well as checking the integrity of all onboard serial communications.
Such features include a flash memory cyclic redundancy check (CRC) function, RAM parity error checking, clock fail and frequency detection circuit, A/D test function and illegal memory access detection.
The Cadence DDR4 PHY IP supports an unbuffered dual in-line memory module (UDIMM)/ registered dual in-line memory module (RDIMM) with reliability, availability, and serviceability (RAS) features such as cyclic redundancy check (CRC) and data bus inversion (DBI).
