GPy firmware update failed



  • I followed the steps to setup the GPy, but am getting a failure message when I try to update the firmware. The message I get is:

    "The upgrade failed, please check the connections and try the steps again."
    "This is the log of the upgrading process:"
    "Connecting..........................."
    "Failure!"

    I am using the expansion board and I have a jumper on the tx pins. I have a wire shorting G23 to GND. I installed the FTDI drivers. I'm getting this error on Windows 10, and I got a similar error running Ubuntu.

    I read from other forums that if I connect to the board using Tera Term and hit the reset button, that the board should identify itself, but I'm not getting anything.

    If I plug the board in without the shorting G23 and GND, the demo application seems to work fine, so I don't think it's bricked.

    Any ideas how to fix this?



  • @jmarcelino

    That fixed the problem! I did not have a jumper on the RX pins. By demo application I mean that when I plug in the board the green LED flashes, followed by the blue LED every 4 seconds.

    Thanks a lot for your help!



  • Hi @jermj93

    Please go through this checklist to make sure everything is correct:

    For example mention you have a jumper on the TX pins, but you must also have on on RX.

    Also what do you mean by "demo application"? You mean you can see the MicroPython interpreter (REPL)?
