Hi Folks,

I am using Tx1 Carrier board and IMX274 from Leopard Imaging. When I run tegra_multimedia_api example ‘multisensor’ I get some error and warnings. Although I do get preview output and JPEG images, which shows both cameras are working.

Would like to understand these warning/message

Thanks

How about sudo ./argus_multisensor and which BSP?

Hi Kayccc, and ShaneCCC

Thanks for your help and Sorry about the delayed update. Running the command with sudo seem to get rid of warnings.

Thanks,
