Hi Everyone, I am using DaVinci DM6446 EVM. I am trying to execute v4l2 sample capture program using D1 size input source. It works fine with MMAP io method but USERPTR io method fails!
1. The sample code without modification in buffer size works well with MMAP but fails in USERPTR 2. If we provide buffer more then or equal to 884736, capture is possible with USERPTR, but driver does not copy frame in the buffer. I am badly stuck here, any pointer will be appreciated. Thanks in advance, Best Regards, Vrox
