Hi,

   The question below

IWR6843ISK: Used Uniflash for demo flashing, but cannot detect the com port.

I asked before has not been resolved, at that time my forum was closed.

I called the customer service in China and they asked me to fill in the CPR form, but I finally found that I could not fill in some problems in my Ti account, and the time was delayed for more than a month. After completing the filling, I was told that the development module could not use the CPR form to fix it, which resulted in this anomaly and I have to ask again now.

Last time, we were told that we did not press the NRST button between the two time flashing, but actually we did press the NRST button, but the problem still occurred and we could not flash now. We really want to send it back for inspection, because it took too long, it hasn't worked since it was purchased.

    Hi Jaly,

    We usually do not accept duplicate threads and you typically would have to respond in the old thread (here), but since you accepted the response of the prior thread, that thread is now closed and considered resolved. So we will honor this thread. 

    To establish a baseline of where you are right now, can you do the following

    • verify the correct drivers are installed, like you did in the prior thread, with a screen shot of the device manager
    • start from standalone mode (ISK only) and show the switch settings
    • show the UART/uniflash errors when trying to flash the device

    We need to work backwards one board at a time to verify where the error may lie.

    Regards,

    Luke

    Yes, at that time, we had a normal flashing once, we thought it was OK and pressed accept, but then the same problem occurred.

    I may need a few more days to do the test according to your request. My company needs to re-apply for computer permission to do flashing.

    Sorry, please give me some time.

    Hi Luke

      Now we are checking our computer again to confirm that it is not the problem of the EVM.

    It might take you a while to wait.

    Hello,

    When you go to device manager does the two COM ports show up? Rather than have all three systems connected at once, let us go one by one. Your 6843ISK EVM has a USB port of its own. Are you able to flash the device with it in the proper flashing mode, USB cable connected from EVM directly to computer with no other attachments, with the correct COM port set? You will need to change the mux switches to the correct mode for flashing mode

    Best Regards,

    Hi Pedrhom,

       We tried to flash with IWR6843ISK  and it  flashed normally.

     However, we tried to use IWR6843ISK + mmwaveICboost and failed to flash properly.

    mmwaveisboost

    switch code: off, on, on, on, on, on, on, off, off, on, on, on

    IWR6843ISK

    switch code:on, off, on, on, off, off

    Hello,

    The switches you have for the ISK is correct for standalone mode flashing, however for flashing using a ICBOOST attached the switches will need to be different.

    After, when you add the ISK board to the ICBOOST, and then attach barrel jack as well as plug usb cable into the XDS110 port of the ICBOOST, the COM port will change. Did you adjust the COM port being flashed to in Uniflash to reflect this change?

    Here is a link to our operational mode guide for all EVMs

    Hi Pedrhom,

          We have tried the method you suggested, but it was also unable to flash in.

    Please give us further instructions. Thank you.
