Configure required pins for trace output

1. Create a file for the device

STM32F429.ini

/*********************************************************************
* Configure pins to enable the trace port                            *
*********************************************************************/

_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

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".
  • Start the debugging session and open an "Instruction Trace" window.
