issues while connecting PureThermal Mini Pro JST-SR lepton 3.5 with raspberry pi and ubuntu

[sandeep1404]

I am using the board (PureThermal Mini Pro JST-SR ) , and I am not using any breakout board and not using purethermal USB.I am getting a black screen in Raspberry Pi with a red box as shown in the below figure attached .

I am following following this repo github

When I tried connecting the camera with my Ubuntu Linux system and try to capture following the github, the camera is not detected by my linux system , but it shows both video0 and video1, video0 is my webcam, not sure about video1, but gives me error when I try using that as shown in the figure

Please help me in this regard, I got a breakout board v2.0 also but not able to get the video feed from that as well, I am completely struck what to do, please some guide me how to integrate my PureThermal Mini Pro JST-SR with lepton 3.5 to my linux system or to raspberry pi anything is fine that would be a great help for me. Thanks in advance.
