  • [Solved] Connection Problem STM32F103

    I have a "Flasher ARM" programmer and would like to program a STM32F103 micro-controller.

    I have connected the programmer via the JTAG-interface over the jtag isolater with the controller. There is a 10k pull-up resistor on TMS,TDO, TDI and Reset (Reset has a 100nF capacitor to GND). TCK has a 10k pull-down resistor.

    The Jlink.exe can't connect to the controller (see attachment).

    I measured the TDO line and it is in fact always high. But i haven't found a fault in my setup yet. The power led of the JTAG isolator is glowing green and the reset led flashes red when I try to connect.

    Is there any additional setup/configuration needed to connect to the STM32F103?

    NOTE:
    Today I tried to programm the device with a ST-LINK/V2 programming tool and it worked on the first try. I connected the ST-Link with the same cable as i had connected the JTAG-Isolator before. So I guess the hardware setup was not the problem since the ST-Link worked with the same cable. But I really would like to get it to work with my Segger Flasher. Any ideas?

    Solved:
    The designer of the board made an error and so it wasn't possible to get into JTAG mode. Sorry to bother you.
