PWM Uninit not working

[dhawal94]

app_pwm_uninit is hanging the code. The control goes to pwm_dealloc() and then in nrf_drv_ppi_channel_free() it hangs.

Using SDK10. I want to change the PWM frequency and have to call app_ pwm_init every time for re-initializing the channel time period. The code doesnt run pwm init twice. Hence, I figured pwm uninit should be done. But its not working.

PAN-73 workaround is there in pwm_enable and disable. Still, I am unable to figure out the issue.

I am having problems reproducing this issue. Can you upload a simple piece of code that reproduces it? Here is my modifications to SDK 10 PWM example, where app_pwm_uninit() is called after a short time one iteration of the original main loop. Using a debugger I see that the call to app_pwm_uninit() is successful in this case. How does yours differ?
