We have completed our hardware test. It seems the signal output of TC358746 CSI Tx mode is ok based on our test.
We built up our driver based on the source code from OV5693, we made some modification.
Please see attached V4L2 error report for error from V4L2 driver. We used the following command line:
Please see attached nvgstcapture-1.0error1 and nvgstcapture-1.0error2 for errors found under nvgstcapture-1.0 command.

I think you can find the status REG from the TRM.

Hi shaneccc,
mode0 {
};
How do I set " pix_clk_hz"? Our sensor output clk is 33.75Mhz.That’s why I set " pix_clk_hz" as this value. And how do I set CSI-CLK frequency?
Does it means tx1 csi channel does not receive any MIPI package according to attachment Vn-Vp.jpg?
Hi Le0Nard0,
Could you share the Excel datasheet and driver code, which allows us to input some basic parameters of camera and generated some values used for TC358746 registers. I am debugging this IC for TX1 now.
My email address is cloundliu@163.com
thanks
@Le0Nard0
We have several toshiba chips working with TX1, let us know if you require additional help.

Hi, David!
I have some problems with starting tc358748 to work in Parallel → CSI mode.
