Re: Allied Vision Alvium Camera streaming issue

I just want to confirm this issue when testing two Alvium cameras G1-500c and G1-577m. I attach the screenshots.

The trick as Sandeep later communicated is to process $(P)$(R)GC_AcquisitionStart once after iocInit.

From Mark's comment about the code.

That just make the problem weirder.

The test with ADAravis driver showed no such issue.

I can write/read all other camera parameters but can't see image streaming (the array counter is not running up). I have followed this <https://areadetector.github.io/master/ADGenICam/ADGenICam.html#python-scripts> link to create template files. I get this message on IOC start
