Driver dies when SPI is enabled
Hello,
I have an IMX477 connected via CSI0 to an Nvidia Jetson Nano development board together with a NeoPixel Ring driven by the NeoPixel_SPI library. I used the following commands to install the drivers:
cd ~
wget https://github.com/ArduCAM/MIPI_Camera/releases/download/v0.0.3/install_full.sh
chmod +x install_full.sh
./install_full.sh -m imx477 # For the Pi HQ camera
After rebooting, the camera seems to be detected (output of dmesg | grep -E "imx477|imx219|arducam"):

After enabling the SPI1 interface by using sudo /opt/nvidia/jetson-io/jetson-io.py, the camera is no longer working. The following output is from dmesg | grep -E "imx477|imx219|arducam" again:

It seems to be that whenever you enable SPI1, the driver/camera dies and when you install the driver, it disables SPI1. Does anyone know if there is something I am doing wrong/forgetting?
SPI2 also is disabled when you run install_full.sh -m imx477. This makes it so that SPI is fully unusable on the Nvidia Jetson Nano board when using this driver.
