CSI port-index confusion

Hi,

Please help me understand,
On the new EVM p3449-b01 there are 2 CSI connectors,
According to the schematics they are connected to J13 CSI0 using 2 lanes, and to J49 CSI2 using 2 lanes,
CSI4 is only connected to TP’s

But on the tegra210-camera-rbpcv2-dual-imx219.dtsi on the 2nd camera the port-index is set to 4.
Also on the 2nd camera modes the tegra_sinterface = “serial_e”;

I also saw on the sensor development guide the following diagram for the nano:

•For NVIDIA® Jetson Nano™, Jetson™ TX2 series, and Jetson TX1::

On our custom hardware we are connected to CSI4 so what should be used for the port-index and tegra_sinterface
Should it be port-index 6 ?

Thanks
Amir

What do you means CSI4?
If your HW is connect to the CSI E, then it’s the same as second imx219. They are start from 0 not 1.

port-index = 4
egra_sinterface = "serial_e

Hi Shane,

On page 5 of P3449_B01_Orcad_schematics.pdf ( I cannot attached an image of the schematics page so please check it at page 5)
CSI0 (J13) corresponds to port-index 0
CSI2 (J49) corresponds to port-index 4

which port-index should be used if i am connected to CSI4 (of the schematics )

Thanks,
Amir

From the pinmux CSI4 is connect to CSI-C for Nano’s design.
The port-index is 2 and serial_c
