I’m having trouble with the SPI pins on the ROCK PI X.
Here are the steps I have taken so far:
- Installed libmraa-rockpiX on Ubuntu 20.04 LTS
(Note: I have gotten the GPIO control to function. Have not tested UART or I2C)
- Ran through this tutorial (https://github.com/up-board/up-community/wiki/Pinout_UP2#spi-ports) for adding an ACPI override to the kernel, as mentioned here (SPI for Linux Support on Rock Pi X).
Here I only found spidev1.0 on my local RPI X
- Tried compiling and running the c++/spi.c example in /usr/local/share/mraa/examples
- Tried opening /dev/spidev1.0 with a file descriptor and writing to it
So far, none of these steps have produced SPI data through the pins. I’m using a Saleae Logic Pro 8 for reading the signals out of the SPI pins
(have tested both the ISH_SPI and the SPI2 pins).
Do you guys have any further steps I can take to make this work?
