Hey there
So I was planning on using the OPZero on a robot that I had already made, which took use of SPIdev, and it was doing calls to the spidev driver in C.
Now I noticed that the OPZero has 2 SPI channels, one for the NOR flash (Which isnt populated) on the back and another that goes to the GPIO headers on the device.
Now I ran my script, and turns out that /dev/spidev0.0 is actually writing SPI commands to the rear SPI channel. This is apparenly SPI0 according to the schematics.
Now following the schematics again, I want to access SPI1, which currently does not exist as a spidev file. I tried "modprobe spidev" to bring up the extra interface, but sadly nothing brought up /dev/spidev0.1 (Which I am assuming is the one I want.)
Any pointers on how to get the extra SPI bus up and running?
Btw, I have confirmed that it is writing to the rear SPI hooking up my logic analyzer to the rear and running my program. The signals came out perfectly on the back one, which is awesome, but I need the ones on the GPIO headers to work.
Thanks for the help!
