the *ini file i used is
but the performance window displays 0 calls 0 time 0% cpu usage.
thank you in advance for any help.

hi,
i am using stm32f7 and for debugging ulink pro, i have tried to enable ETM but not succedded. the connector i am using is, where traceD0-D3 are PE3-PE6.
the *ini file i used is
/*-------------------------------------------------------------------
** Define the function to enable the trace port
**-----------------------------------------------------------------*/
FUNC void EnableTPIU(void) {
_WDWORD(0xE0042004, 0x000000E0); // Set 4-pin tracing via DBGMCU_CR
// _WDWORD(0xE0042004, 0x00000020); // Set 4-pin tracing via DBGMCU_CR
_WDWORD(0xE000EDFC, 0x01000000); //
_WDWORD(0xE00400F0, 0x00000000); //
_WDWORD(0xE0040004, 0x00000008); //
_WDWORD(0xE0001020, 0x002002CA); //
_WDWORD(0xE0001024, 0x0000000); //
_WDWORD(0xE0001028, 0x00000008); //
_WDWORD(0xE0041004, 0x00000000); //
_RDWORD(0xE004100C, 0x00000003); //
_WDWORD(0xE0041040, 0x00000002); //
_WDWORD(0xE0041080, 0x00000001); //
_WDWORD(0xE004108C, 0x000000FF); //
_WDWORD(0xE0041004, 0x00000001); //
}
/*-------------------------------------------------------------------
** Invoke the function at debugger startup
**-----------------------------------------------------------------*/
EnableTPIU();
/*-------------------------------------------------------------------
** Execute upon software RESET
**-----------------------------------------------------------------*/
FUNC void OnResetExec(void) {
EnableTPIU();
}which was given in reference manual as
4 Configuration example
To output a simple value to the TPIU:
•
Configure trace I/Os: enable TRACE_CLKINEN in the STM32F75xxx and
STM32F74xxx debug configuration register (DBGMCU_CR).
•
Write @ E000EDFC 01000000; SCS: set TRCENA, otherwise trace registers are not
accessible.
•
Write @ E00400F0 00000000; TPIU: select SYNC PORT Mode
•
Write @ E0040004 00000008; TPIU: select TPIU PORT SIZE=4
•
Write @ E0001020 002002CA; WT: PC MATCH Comparator (PC=0x2002CA)
•
Write @ E0001024 00000000; DWT: No mask apply on comparator
•
Write @ E0001028 00000008; DWT: ETM trig on PC on match
ETM:
•
Write @ E0041004 00000000; Disable ETM
•
Read @ E004100C 00000003; ETM should be in Idle state
•
Write @ E0041040 00000002; Instruction trace source ID = 0x2
•
Write @ E0041080 00000001; Resource for ViewInst enabling event is “always
TRUE�?
•
Write @ E004108C 000000FF; Processor comparator selection for Start:
pc_match0 (=>DWT match)
•
Write @ E0041004 00000001; Enable ETM
the debug settings i have also attached
but the performance window displays 0 calls 0 time 0% cpu usage.
thank you in advance for any help.
