I’ve been attempting to add additional chipselect lines to the SPI on the AGX’s 40-pin header. I’ve added an entry for the
cs-gpios field in the device tree for the SPI controller as per the documentation in the linux device tree documentation and accordance with this forum post: TX2 R28.2 SPI CS-GPIO issue
Are there any known issues with using
cs-gpios with the AGX? Is there any special configuration required for the GPIOs in order to have them used by the SPI controller?
