3.2 CPU_04

The Instrumentation Trace Macrocell (ITM) and Data Watchpoint and Trace (DWT) are active only if an external debug probe is attached to the JTAG port of the device.

Revisions affected:

Revision C

Details:

The debug subsystem power domain, which enables both the JTAG/cJTAG debugging and the trace capabilities of the device (ITM and DWT), remains powered off until a debug probe is attached to the JTAG port of the device. This prevents using any trace capabilities (data watchpoints, semihosting) in a standalone device.

Workaround:

Power up the device with a debug probe attached, which also powers up the debug subsystem and maintains the functionality of ITM/DWT until a reset is issued.
