10. EEPROM emulator how to use on Maple Mini ?

    madias· Thu Sep 17, 2015 3:19 pm

    As the maple mini is a STM32F103RCBT6 (so “RB”) you should use " 1 set configuration to 0x801F000 / 0x801F800 / 0x400 (RB MCU)\r\n" \

    I’ve updated all the Maple upload scripts with @danieleff’s suggested fix I’m not sure if it will cause problems for Rick if he is not using the Arduino Serial Terminal, but the worst case should just be a short delay (timeout)
