Use the nrfutil trace stm command to collect System Trace Macrocell (STM) traces from devices that support STM tracing. The trace can be used to gather logs from multicore devices such as nRF54H20 and analyze device communication.
Note
- This guide is only available for the nRF54H20 device.
nrfutil trace stmrequires the nRF Connect SDK v3.4.0 or later to work.
