Enable ETM trace on IMXRT1052

[michaelsmith]

How to enable ETM trace on IMXRT1052 processor using Keil ARM MDK?  What registers (e.g. IOMUXC, CCM, etc) need to be configured to output the trace data.  How to set up the debug/trace dialog in Keil IDE?

Hi Michael,

According with section 7.2.2.3 “Embedded Trace Macrocell (ETM)” of i.MXRT1052 Reference Manual, in case of requiring information about ETM, it is required referring to “ARM® CoreSight™ ETM-M7 Revision r0p1 Technical Reference Manual” document (link below), as it is part of the ARM debug features:

Additionally, you also need to ensure that you have a proper debug tool that supports ETM features, like the Segger J-Trace:

Hope this will be useful for you.
Best regards!
