STM32F429I-EVAL ETM Trace not working I recently purchased a STM324F29I-EVAL board. I am using Keil uVision 5 along with a ULINK Pro debug probe. I have been able to get the basic ITM trace to work via SWO however the 4 bit ETM trace I am not able to get working. I've verified that pins PE2 - PE6 are enabled and reconfigured for trace functions by a debugger script. I've tried it at various CPU clock frequencies even as low as running the core directly off the HSI of 16mhz but I still get a No Synchronization error in the debugger. There is no problem with my debug probe as I can run the full 4-bit ETM trace on another project I have that uses the LPC1769 MCU. Has anyone else experienced any issues with the ETM trace with this part or the eval board?
