I'm working Internal ADC. i need to know what is difference between ADEVT And normal gpio trigger. 

You can trigger with either GPIO or ADEVT externally.

For example, if you want to trigger ADC using GPIO configure as below:

For more details you can refer the HALCoGen ADC example:

Take this as reference and try to implement the code on your own. 

If you are unable to implement your code, then give me some time to create an example for you because i was stuck with other issues as well.

I tried and implemented in various method means both hw and sw trigger, when im taking ADEVT PIN as trigger source its updating 1sample at one trigger. is it possible in 1 trigger 64 word i can update like gpio example?

hi Jagadeesh thankyou, i made some minute changes it worked. i need one more scenario if i config  adc1 ch0 with all groups what it will happen with hw trigger.

Good to hear that!

You can select single channel in multiple groups, and it just increases the samples of the corresponding data.

For more details refer the below highlighted paragraph:

And if you give the same trigger for all the groups then as mentioned in above paragraph, event group have highest priority, so the corresponding channel is converted into the event group first, and then group1 selected channels will be converted and then group2. If you select same channel in multiple groups, then it will get converted in multiple groups and increases the samples.
