Looks like it capture successfully.
Please have a check if t.raw validate.
Hi Shane, thank you, the file is 0 byte, I am not sure if it is relative with the V4l2 verify fail 3, will check more; and there is CRC issue with my device, TX2 just display the flag, do nothing like other SOC, right?
You can try the patch to disable the ECC check from below link.
Hi Shane, thank you very much, Now I can get image, the device can output 4 channels video by virtual channel mode, so I need to change the DTB and driver to match it, do you have some guide for DTB? or any other item need to change?
You can reference to ./t19x/common/kernel-dts/t19x-common-modules/tegra194-camera-imx390-a00.dtsi for virtual channel support.
Hi Shane, I can follow the Hosti1x and nvcsi for 4VC, but for I2C device, no devnode=“videoX” found, I guess it should list devnode=“video0”~devnode=“video3” with 4 modules, is it right?
Not really understand your question. But yes if your are 4 VC you should have 4 video node.
Sorry, i don’t find devnode=“videoX” in imx390 dtsi file, not sure it is defined at other place or it use other way.
Doesn’t need this property, it already deprecated.
hi Shane，After I change the DTB to 4 VC mode, the driver print below issue, our device just one I2C, so I set other three
reg = <0>;
this drive is OK at single channel mode.

You can’t have the duplicate slave address on the same i2c bus.
Yes, I see, I just have one valid I2C device with four channels video via VC mode output, I am not sure how to transfer the 4 dev node via one I2C device in DTB and driver
You can make a fake slave address for 3 of them and handle it by your kernel driver.
Hi Shane, thank you, I got 4 video nodes by using fake slave address, below is device virtual channel mode timing, is it OK for TX2 MIPI CSI?
It should be OK.
Hi Shane, thank you, still have some issue with VC mode, below is some log, would you please help to check if there is some issue
