Serial Wire Viewer (SWV) on STM32F100

Hello,

I'm trying to use the serial wire viewer with the STLINK/V2 and the STM32VLdiscovery kit. The embedded debugger is bypassed because it doesn't support SWV.Debug is OK but there is no signal on SWV. The pin 13 of the debugger is connected to PB3 (TRACESWO). This signal pin is in the Remap function, but I don't know how to reconfigure it (if needed). GPIO_PinRemapConfig() function doesn't define about TRACESWO...Note: SWV works with my STM3220G-eval but for PB3 there is no remap to do.Thank you for your help.Pierre

I suspect it may be somehow related to the following problem:
