Data retrieving using HPS in DE10-Nano

Hello, I've been working on a project that consists in program a DE10-Nano to use it as a photon counter. The idea is to count TTL pulses fired by a photon detector. I previously asked here for help...

    Hi,

    Yes, I already made changes to the device tree files. As I said before, I did some good advancements following the guide I refered. What I'm asking help about, is more about the C code and Verilog code synchronization to achieve my desired behaviour. With the C code, I'm looking up the counting variable I designated in the Verilog code, however, as I mentioned, this does not get me all the intervals I should be getting. Plus, if I'm using a Signal Generator of 10 MHz, this would mean at the end of every interval I should be getting counts of 1000 pulses, however, at certain intervals, I get different values (some around 1000. some not). Is there a better aproach for this?
