Josh Blackburn Posted October 14, 2023 Share Posted October 14, 2023 I'm trying to use an SPI driven TFT display on the orange pi 5, but I'm stuck on enabling SPI in the first place. Looking at the pinout of the orange pi 5 in its manual, it appears that SPI4...M0 is the only bus broken out to the pins. However, enabling "rk3588-spi4-m0-cs1-spidev" in the armbian-config menu does not seem to do anything, as no /dev/spi device exists after a reboot. Enabling any of the other spi hardware functions seems to work just fine, creating a /dev/spi device as expected, but none of the other spi busses are accessible through the pin header. I'm on Armbian 23.8.1 (image: Armbian_23.8.1_Orangepi5_bookworm_legacy_5.10.160.img). Has anyone used SPI on the Orange Pi 5 before? 0 Quote Link to comment Share on other sites More sharing options...

royk Posted October 15, 2023 Share Posted October 15, 2023 (edited) @Josh Blackburn Do you have the overlay files in? /boot/dtb/rockchip/overlays/ Is the right prefix set in armbianEnv.txt? Other overlays activated that uses the same pin? Edited October 15, 2023 by royk 0 Quote Link to comment Share on other sites More sharing options...
Josh Blackburn Posted October 15, 2023 Author Share Posted October 15, 2023 @royk I had apparently enabled UART3_M0 at some point, which does indeed conflict with SPI4_M0, disabling UART3 worked. Thank you for bringing that to my attention. @Werner Apologies, I will be sure to include that log in future posts. 2 Quote Link to comment Share on other sites More sharing options...
