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!
