Hi sir,
i am using cx3 chip connecting a sensor, which as "varied" V-Blanks time... the sensor can be running 120fps
i am able to get a whole frame without issue.. however, it seems the issue of "dropped frame" is happening... the actual fps on PC is only half by checking the frame_count in "embedded line data"....
suspecting the "varied" v-blanks is the root cause?
how can i further narrow down the issue?
many thanks

Hi Akeem,
1. Could you please upload screenshot of Image sensor configuration and CX3 receiver configuration tab in .cycx file?
You need to ensure that all the values are correct, without any error(red cross).
BTW, which sensor are you using? Why does the V_blanking value vary? Considering this case, please verify the parameters with minimum V_blanking value.
2. Please check if you get any error message when commit DMA buffer.
