Hi

i do have the B-L072Z-LRWAN1 board and try to make a End-node..

When i want to debug the Stm-cube LRWAN END NODE exsample it gives me a failure ...the port is in use ?

What can i do wrong ...Normally absolut no problems...

Both Keil and openstm32 make the failure..

Anyone know ?

    Hello

    ‌,

    to achieve lowest possible current consumption, SWD pins are set to analog mode without pull resistors and this is causing you error on debug.

    Check for define LOW_POWER_DISABLE and uncomment it. In this case, pins won't be changed and you should be able to debug.

    Best regards,

    Disable low power modes where it turns OFF the JTAG/SWD interface.

    See define LOW_POWER_DISABLE

    Please post the exact message you get, and describe the exact steps you take up to getting it.

    A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    Hi tilen

    thanks for your help.

    it worked...

    i do program on the board you teach us in Copenhagen, and my lora node is doing progress.

    i did also set up my own lora gateway on a raspberry so Now looking into a very interesting World.

    just order some stm32L0 sx1276 and Will get Them to work When finish with the initial test on this board...

    thanks for you help again
