I need to do execution profiling on an STM32F405 (Cortex-M4). My firmware is built using MDK-ARM Professional 5.40. I have debug access via SWD + SWO; I don't have the available I/O to support ETM.
Debug adapters I currently have on hand are the STLINK/V2 and the Keil ULINK 2.
What I need to know: What are the minimum requirements for execution profiling with this processor and IDE? Is the ULINK 2 sufficient, or do I need a more expensive debug adapter?
It is surprisingly difficult to get an answer to this question from the available documentation. Plenty of sales talk, very little useful information.
Thanks,
