I think the python interface and robot tests can be structured and simplified, however that can be done in a follow up PR (by me). Still some changes to the shell-based test firmware

should be timer_set_absolute to match (current) API

error case is not checked here and below, i.e. CONVER_ERROR

the error case is not evaluated in many cases where this function is used. Maybe change to
static inline int _get_num(const char *str, uint32_t *val)
and return value by reference and error as return?

This the first few tests for periph/timer.
To make this work properly on all boards we need to provide the debug pin configuration with the environment, i.e. tell the test which pin of the DUT is connected to DEBUG0 of PHiLIP
Known issues:
The trace mechanism of PHiLIP sometimes reports timings that are not accurate.
This causes problems with the jitter test because sometimes delays around ~1.8 ms are added to the actual measurement. I verified with the scope that the timing deviation in this case actually didn't come from the DUT.
I discussed this offline with @MrKevinWeiss and we agreed that the best solution for this would be to use the capture features of the PHiLIP timer.
