I use a hardware timer to capture/compare incoming pulses using PPI to trigger the captures from GPIOTE. I previously wrote the same application for nRF52832 on the old SDK using TIMER4 and it works well.
Am now writing code using nRF54L15 which works OK. But I need to port the same code to nRF52832. If I run the same code on 52832 I get kernel panic.
Before I spend too much time chasing the panic I want to verify which timers I can safely use on the nRF52832? Note I'm concurrently using a Zephyr timer k_timer_start() for other purposes.
For info, this is the panic
