Using semihosting on supported architectures (arm, xtensa, riscv) it now possible to generate tracing giles easily and without being restricted by size. Using qemu for example, it is now possible to generate the tracing file simply by running: west build -p -b mps2/an385 tests/kernel/msgq/msgq_api/ \ -t run --snippet semihost-tracing This will generate a tracing file in the build/ directory which can be viewed with babeltrace.
