I am triggering adc every 100us in dma and getting data in adc callback. I am triggering adc with hrtim compare 3.
//hrtim cmp3 event call back
{
//reset a pin.
}
//adc conversion call back
{
//set a pin
}
for some reason the reset pin is working every cycle but set pin skips its cycle.
It means adc call back not working every cycle?
What can cause this kind of behavior?

Hello,
To me, it could be either the NVIC priority Level or the timing 100us which is very relatively high to let ADC interrupt handler to be executed.

Should i priorities adc interrupt as high?

This just for test to understand the behavior.
But you need to do one test (1 or 2) at a time.
