What is the compatible string for the SPI driver

[thangtamfive]

Hello what SPI Driver does the Red Pitaya use and what is the compatible string? In fact, how may I find the list of devices used by the Red Pitaya?

Regards!

Can you explain a bit what you are searching for?

Userspace access to SPI is provided using character driver https://github.com/RedPitaya/linux-xlnx ... i/spidev.c available at /dev/spidev1.0
One example to use it is at https://github.com/RedPitaya/RedPitaya/ ... /spi/spi.c
As a reference I generally prefer https://github.com/RedPitaya/linux-xlnx ... dev_test.c, for hardware testing you can actually use this application straight from bash.

List of all devices used by kernel is inside devicetree. Simplest way to search it is in /opt/redpitaya/dtraw.dts or just cating stuff from /proc/device-tree, since that represent current state of devicetree.

Cheers,
