2-12 Servicing the CPU
2.5 Build EEPROM Command
Should the EEPROM become corrupted, you can use the build
eeprom command to recover. The build eeprom command is the
proper response to the console error messages shown in Example
2-4. If the build eeprom command fails, return the module for re-
pair.
