Help to improve FPGA DMA on cRIO-9068 and ni-9201

[Frankr21]

I am  trying to add 2 NI9201 module to my cRIO-9068 (FPGA code was previously build by another person) and i need to run the acquisition as fast as possible. I am new to work with FPGA so not sure what is the best way to approach the programming.

I have tried to different way but they both return me different result. I am tying to measure a pulse of 80 us and i know the module can read each channel at 2us, since i use 3 channel on each of the 3 ni-9201. I think i should be fine if i take 100 sample to cover the whole pulse?

When reading the data on the host i see the pulse on one channel and only get peak on the other channel of the same module.

Any advice will be welcome. 

Using Labview 2015.

I should have tried the example VI of the NI 9201, it has fixed all my issue. 

I was just to lazy to modify the RT code, but it will be better i guess.

 Much cleaner anyway
