Alternative Boot EEPROM - - Upon the kmeter1 startup the I2C_1 controller is used to fetch the boot - configuration from a serial EEPROM. During the development and debugging - phase it might be helpful to apply an alternative boot configuration in - a simple way. Therefore it is an alternative boot eeprom on the PIGGY, - which can be activated by setting the "ST" jumper on the PIGGY board. - -2.
