Configure required pins for trace output
1. Create a file for the device:
/*------------------------------------------------------------------- ** Define the function to enable the trace port **-----------------------------------------------------------------*/ FUNC void EnableTPIU(void) { _WDWORD(0x40023830, 0x00000010); // Enable GPIOE clock _WDWORD(0x40021000, 0x00002AA0); // Configure PE2, PE3, PE4, PE5, and PE6 as AF _WDWORD(0xE0042004, 0x000000E0); // Set 4-pin tracing via DBGMCU_CR } /*------------------------------------------------------------------- ** Invoke the function at debugger startup **-----------------------------------------------------------------*/ EnableTPIU();
2. Set the file as initialization file
- Open the dialog "Options for Target - Debug".
- Set the created file as Initialization File.
Configure µVision for ETM trace
- Click Settings to open the "Target Driver Setup" dialog.
- Click the Trace tab.
- Set Enable and ETM Trace Enable.
- Set Trace Port to "Sync Trace Port with 4-bit Data".
- The Core Clock must be adjusted accordingly the device configuration.
- Start the debugging session and open an "Instruction Trace" window.
