PWM Timer on the Wireless UART example not working

I am usgin the QN9090DK.


I have followed the code in the pwn_output sample project to define my own PWM timer in the wireless_uart sample project. While the timer is operational in the pwn_output project, it does not work in the project based on the wireless_uart project.


I have tried the above on both the BM and FreeRTOS versions with following results:

- In the BM project, the IRQHandler is not run/hit at all.

- In the FreeRTOS project, the IRQHandler is run/hit once, with a strange behaviour: the handler function tries to print "test", and on the terminal I get "t" printed, and only once, whist the timer is set to run forever.


I can't understand what is going wrong in both cases.


Kind help would be appreciated.
