I’m trying to connect the RPi Camera to the Jetson TX2 through the CSI-CD port of the J90 Motherboard. According to the technical reference (https://auvidea.com/download/manual/J90/J90_technical_reference_1.2.pdf, Page 9), the pin GPIO3_CAM0_RST must be set to high to enable the camera module, and a low pulse performs a power on reset.
We can see in the Jetson TX2 Generic Customer Pinmux Template that GPIO2/CAM0_RST# correspond to GPIO3_PR.05 = GPIO 161 in gpio-names.h. To access this GPIO, we need to write 461 to /sys/class/gpio/export (320 + 161)
To to toggle the GPIO 161 low briefly i launched these command :
cd /sys/class/gpio/ echo 461 > export echo out > direction echo 1 > value echo 0 > value echo 1 > value
Normally, at this point, i2cdetect -y -r 2 must detect a device at address 0f and gstreamer should work. But nothing happen. GStreamer fail to open the camera, and i2cdetect -y -r 2 show nothing at the address 0f. (I also tried with GPIO3/CAM1_RST#)
Is someone have an idea of the problem ?
