Marlin 2.0.5.3 "err: EEPROM Version" on ReArm (1 reply)

Had a successful upload of Marlin 2.0.5.3 to a ReArm CPU, However I am now getting "err: EEPROM Version"

Did an M502 and then an M500, but error persists.

This is a new install not an update.

Anybody have this issue? FIX?

Thanks for the assistance.
