Description

We got an error with opcode 202 on BcuNumber3 when writing into DSP memory during frame grabbing.

This could be related to the fact that the bus is busy in transferring the frame.

The occurence is high: one every few (2-3) attempts we got the error.

Disabling the ADCClocing before the write operation seems fixing the problem:
lgsw.wfscamera.deactivateADCClocking(); 
lgsw.controllerClient.setDarkFrameTag('zeros');
lgsw.wfscamera.activateADCClocking()

The BcuNumber2 does NOT show a similar behaviour and it has a different firmware versions (11.67 and 8.44)
