Hi,
We are currently testing ar1820 image sensor through mipi interface of tegra K1 development.
We are able to write (Configure) the ar1820 registers through v4l2 I2C driver.
Device is also detected (/dev/video0). When we try to capture the image through yavta utility, it throwing the following error.
