 		 #127294 - I still say that crc's and checksums only work
Responding to: ???'s previous message
In serial comms or bootloaders where they serve some useful purpose otherwise most 8052 derivatives support verification of the code as it is written to the flash,making other checking of the code in the flash redundant,I dont know if flash fails after 20 or 40 years but most products dont survive that long out in the field.
