EEPROM checking
Hi all,
dose anyone know of a way a BS2 can check it's EEPROM before it starts it's program? What I mean by check it's EEPROM is to see if there are any errors·or any bad program slots.
thanks,
TC

You could READ the individual bytes from 0 to 2047 and calculated a
checksum or CRC. Since you mention program slots, maybe you also
want to do that on a BS2sx, BS2e or BS2p. It is easy to extend the
checksum to all banks on the BS2p, because you can access the entire
eeprom memory through use of the STORE command. On the BS2sx or
BS2e, you will have to load a small program into each bank to check
the eeprom memory for that bank.
