Hello NXP team,


we are configuring DMA based Gpio pin for pulse counting.


We have referred NXP application note for configuration and reading the pulse.


if I use DMA Channel 0, then it is working fine.


for other channels , I am facing some issue. always pulse count (Transmission count ) is 0.


attached the Example code and pdf referred for the DMA configuration.


in main.c file , changing the channel by modifying the macro


#define Channel_DMA  0
