Hello everyone,

I’m currently working to connect external SPI devices to the VOXL2 and integrate them in PX4. I’ve successfully managed to connect a device to J10 (apps_proc SPI) at /dev/spidev14.0 and manage it from PX4.

Now, I’d like to know if there’s a way to use the second chip select line (CS1_N/GPIO_46) to manage two devices. I initially thought that the second device would show up as /dev/spidev14.1, but it is obviously not present. Is it possible to achieve this? Does it require a kernel rebuild?

Any guidance or suggestions on how to approach this would be greatly appreciated!

Thank you in advance for your help!

Best,
Piter
