Cube Blue - Which version of FW?


I have an H7 blue cube that was running ArduCopter 4.1.1 on it for a long time and worked well. I just updated to 4.5.3 and now it is just ticking but not sounding like its booting. I get the correct startup sequence and no error lights. Should I try the newer versions of PX4, although I prefer ArduCopter?

In short, I was looking for what version of the two firmware choices are best to run on the H7 blue cube.


Edit: So reviewing the log, it appears that 4.3.5 is running fine, its the Herelink that is all messed up after the update.
