To enable 4-Pin Trace with STM32F429 device:
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
Configure µVision for ETM trace
