  • How to program a PIC32MX?

    Hello.

    How can i program a PIC32MX.

    I've tried to program the controller (using latest JLINK v7.94g), but i always get a error message: "Writing target memory failed."

    Is it even possible to program a pic32mx with the segger jlink, or can you just delete it?


    Here the commands:

    C:JLink.exe -device PIC32MX -if ICSP -speed 1000 -autoconnect 1 -CommanderScript pic32S.jlink

    The sript file is:

    Source Code

    1. ERASE
    2. LoadFile D:\SEGGER\Software\BPS191.hex
    3. EXIT

    The output is:

  • Hi,

    Well, you need to pass the correct name to J-Link…
    Not all devices share the same algorithm and flash size, so J-Link needs to know which device it is talking to, in order to have the correct algorithm selected.
    List of valid device names for PIC32MX family:

  • Hi Alex.

    Thank you for the answer.

    Unfortunately, the used microcontroller ( PIC32MX130F128H ) is not yet in the list of supported derivatives.
    That's why I tried to do something with the general device specification ( PIC32MX ).

    Very unfortunate.

  • Even more unfortunate that you did not mention the exact device in use in the first place and that you were missing support,
    but instead let us guess and invest time into an answer that you already knew / probably expected...

    However, I invested some more time and checked for a quick solution:
    You should be able to use the PIC32MX130F128H by selecting "PIC32MX150F128B".
    From the debug & flash programming point of view, they should be compatible.

    Can you please give this a try and provide some feedback?
    If it works, we would add the PIC32MX130F128H "blindly" for the next version.

  • Hi Alex.

    Thank you for the great support.

    I tested it, but unfortunately it doesn't work.


    Following is happend:


    I test this combinations:

    ###############################################################

    Than i try the segger JLink with the Microchip studio. It says:
    Connecting to JLink Probe...
    Connection Failed
    Comm library returned an error code of -261, Could not find supported CPU.

    ###############################################################

    Than i use the microchip-studio to erase the device with a microchip snap programmer ( -> is working without problem) and disconnect the now erased device.

    ###############################################################

    After that i reconnect to the JLink.
    Now, with the "Pre-Erased" device, Jlink is now working a little bit ( but not with another NEW and unerased device !!!)

    Now i try to programm the device eith the JLink:

    After that it was no longer possible to erase the device.
