    Hello,

    I’m having issue with my board. It’s being unresponsive to serial command (using my own application, or coolterm). The board is on, and the red light (not sure which one, I can’t open my enclosure right now) is constantly flashing every seconds as soon as the board is on (or even immediatly after a reset).
    When sending serial commands, the RX led is blinking correctly on the board, and I double checked my sent command using a spy on the serial port : they are correct.

    I’ve been using it for a while now to develop my TinyG control application, but suddenly it does not respond.
    Does the red light describe an know issue I’ve been missing ?

    I already had a similar issue here :

    TinyG Support

    I had to reinstall the firmware, but I’d like to avoid doing this every few weeks…

    Thanks

    Hello,

    I tried to reinstall the firmware, but avrdude cannot connect to the programmer. 

    C:\Program Files\arduino-1.0.4>avrdude -p x192a3 -P com4 -c avr109 -b 115200 -U flash:w:tinyg.hex

Connecting to programmer: .avrdude: butterfly_recv(): programmer is not responding

C:\Program Files\arduino-1.0.4>

    I’m under Windows 7, using board v7. I already did that before on this thread :

    Synthetos board does not respond


    But can’t do it anymore…

    Any idea ?

    psyko,

    This sounds like what was happening to the old version of the bootloader. Do you have a AVRISP MKII? If you do I would reflash the xboot.hex and apply THESE settings:

    TinyG Fuses

    If you do not lets have you send this board back and get it re-flashed and the fuses set right.

    Hello,

    Thanks for the answer. I do not have the AVRISP MKII programmer. I think I’ll buy one because it’s always useful. I live in France so I’m afraid the shipping cost will be more than the price of a programmer…

    Ok I tried with AVR Studio 4 and got the error while trying to read fuses :

    “The selected device does not support ISP programming”

    Is that normal ??

    psyko,

    Sorry tracking a bunch of different posts / issues right now. Are we good? Are you getting the support you need? Let me know if I missed something.

    Hello,

    I managed to get the board working by flashing the xboot and reinstalling the firmware.

    Thanks
