Lukas S Posted January 20, 2021 Share Posted January 20, 2021 Armbianmonitor: http://ix.io/2MHP Hey, I am using the Image from the Armbian Download site: Armbian_20.11.6_Bananapim2zero_bullseye_current_5.10.4 and I am trying to get SPI to work, enabled it using armbian-config and through editing the /boot/armbianEnv.txt verbosity=1 bootlogo=false console=both disp_mode=1920x1080p60 overlay_prefix=sun8i-h3 rootdev=UUID=034edbda-9395-4820-87a1-f3a83bad8a58 rootfstype=ext4 overlays=spi-spidev usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u But after a reboot it does not show in /dev/ (what seems odd, i2c-0 shows in /dev/ even though it is not enabled in the armbianEnv.txt) As far as I understand it, the dts for h3 should be the same for h2+ ? I also found a file called "sun8i-h2-plus-bananapi-m2-zero.dtb" under /boot/dtb after some research I found out that this is a device tree binary (thats also why I cant read it) but I couldn't find any information on how to use it. Or how I could replace the spi-spidev.dtd with this h2 one. I also already tried the focal_current_5.10.4 Image same result. Thanks in advance Lukas 0 Quote Link to comment Share on other sites More sharing options...

Thank you very much, should the armbian-config have set this option ? Sorry I didn't find it in overlay documentation that this flag is needed ^^ 0 Quote Link to comment Share on other sites More sharing options...
