Part Number:PROCESSOR-SDK-AM335X

Tool/software: Linux

hi Mike

e2e.ti.com/.../223368

        I test your code, "0317.TestRepeatOpen.rar" on my board , also have the same problem.

        I make a program using QT and opencv to test my camera , it also fails with "select timeout".

       Any suggestion to me?

       thank you.
