Hai,
We are using Analog Devices chip ADV7281-M(Camera input SD video decoder) that accepts CVBS analog
video input data (captured from a camera), decodes it & outputs in MIPI-CSI format. This MIPI CSI data is fed into the SOC which is
processed & then later sent for display.We are using the Linux Driver software from the downloaded from analog Devices Git Hub https://github.com/analogdevicesinc/linux/blob/adv7280/drivers/media/i2c/adv7180.c
I am creating a test framework to verify whether Analog Video input data is decoded properly & also whether the decoded data is transmitted over MIPP-CSI. The chip provides certain registers using which I can verify the decoding status. However excepting the MIPI powerdown registers no other status registers exist to know MIPI data transmit status so I need your help on how to create the test framework
for testing the MIPI data .Do you have any test apps that I could use to test the MIPI data?
As of now, one possible way of verifying MIPI that flashed to my
mind, is to write a test application that uses v4l2 capture framework i.e the
test application shall capture the frame & will be write to some
file. Later this file shall be converted into some known format(?)
& verified. I
feel that this method is not user friendly so Please recommend if
any other means exist for validating MIPI data
