AML-S905X-CC Wiring Tool Overlays Description

This is a list of device tree overlays provided by the Libre Computer Wiring Tool and what they do.

If this document is not up to date, please let us know.

There are a lot more functionality not exposed in which you have to write your own overlay. These serve as simple references for you to get started with.

so by activating spicc.dts the spi pin 19-21-23-24 on the 40 pin should work just like it does on rpi?

Raspberry Pi SPI is usually the spicc-cs dtbo where /dev/spidev0.0 is enabled by pin 24 and /dev/spidev0.1 is enabled by pin 26. You can use the ./spidev-setup cs1

If using the new raspbian distro image, would you still need to run the wiring tool and activate the right SPI to have the same pin layout and usage as the pi?

Yes, Raspberry Pi depend on the bootloader to read config.txt. Our bootloader does not read it at all. We are exploring creating a service to do it but that’s still in the conceptual stage at this point.
