E8a connect H8S2398F20

Hi everybody,

     Please guide me how to connect the E8a to the H8S2398. I used FDT 4.09 to load the program but failed to boot. Thank you

  • Hi Leson,

    Have you found a way to get it work?

    I have connected myself as schematics but FDT still did not find H8S2398. The E8a's manual does not indicate how to connect to the H8S2398 / 2357. Please tell us how to connect to H8S2398
    Thank you

    Your error indicates that the board you are connecting to is externally powered.
    The tool is expecting it to be unpowered.
