Hi,
Thank you for your reply. I tried everything from my side but still the same issue. So I put lot of pressure to Avermedia and got a BSP file with jp 5.1.1. I was also advised that 5.1.1 is very old and even nvidia might stop using it. So we are planning to port our dev work on orin nano super with latest and stable jp version for future deployments.
Thanks once again for replying. Im closing this thread. :)
