Posted on May 17, 2011 at 13:10I am trying to debug the alternative SPI1 port using IAR with Jlink connected to a STM32F103RB over the SWD wires.
The problem is the SPI1 Clock shares the SWO pin and I cannot seem to disable the SWO interface and Keep the SWD.
The Single Wire Debug works fine without the Single Wire Output connected.
The SPI1 SCLK works fine if I completely disable all the debugging ports with:
GPIO_PinRemapConfig(GPIO_Remap_SWJ_Disable, ENABLE);
But not if I disable only the Jtag with: GPIO_PinRemapConfig(GPIO_Remap_SWJ_JTAGDisable, ENABLE);
I even set the TRACE_IOEN bit off (by editing the debugger configuration file) but this did not help.
Does anybody know how to configure this to work ?
Maybe it is a mater of just turning off the HW Trace for SWO Setup but this only seems to take effect after the debugger is loaded.
Am I missing something ?
