e-con Systems e-CAM50_CUNANO

Posted on Edited on In ,

I kept an eye on e-con Systems for over 3 years. Finally, I decided to try its products this year (2020). Today, we are going to test its newly product e-CAM50_CUNANO on NVidia Jetson Nano, actually, a NVidia Jetson Nano 2G. Please find all documentations from e-CAM50_CUNANO's website. Here, we'll follow e-con_e-CAM50_CUNANO_Developer_Guide.pdf.

Such a busy year, unbelievably busy. I can't believe when I started the investigation of e-CAM50_CUNANO again, it's already been a year after. Okay, let's start.

  • It looks by directly plug in e-CAM50_CUNANO onto Jetson Nano 2GB Developer Kit, there is NO camera detected.

Therefore, it looks we need to build a driver of AR0521 for my board: - hardware: Jetson Nano 2GB Developer Kit - software: Jetpack 4.5.1
