Olimex STM P103 Setup

Simon Newit

Hello

Im currently trying to communicate to the STM32F103RBT6 microprocessor sat on an Olimex STM32 P103 development board.

Using a Ulink2 debugger coupled with the latest evaluation version of uvision (MDK432)and I can't get the JTAG communication to recognise the device in the chain dialog box.

I have seen simular threads to this, however non that address this particular issue. Can anyone outline the steps to resolving this problem?

Thanks
Simon

    'play' with the values in options for target>debug and options for target>debug>settings.

    it worked here

    PS your problem will show if the target board is not powered.

    Hi Erik

    Thanks for your fast response,

    I've tried the following to no avail:

    Altering the clk settings (1M>5kHz)
    Changing the cache options
    Changing the target devices to similar.
    Changing the debugger settings.
    ...and various combinations of the above.

    The only thing I haven't attempted is manual configuration in the JTAG chain dialog box. Would it be possible to pass on your configuration settings if you have the same device?

    Thanks
    Simon

    PS target board is powered via the debugger (Ulink2) and is indicated via the power LED on the dev board

    everything default except set at 1MHz

    what happens if you power the board. I have seen many 'funny' really 'not so funny' results from USB powering of devices especially when powering from a laptop.

    Erik,

    Swapped the power supply from USB to External Power supply and has cured the problem.

    I will investigate why there is a problem powering through USB at a later date, your right it was not so funny!

    Many thanks for your time and advice!!
