    i'm change all of sun50i-h616-spi* dts files to`compatible = "armbian,spi-dev" but nothing. CS is OFF! Maybe the reason is that it's called CE. In gpio readall CS is name CE.

  4. Orange pi zero 3 SPI cs pin

    adif posted a topic in Allwinner sunxi
    I'm trying to configure the CS (Chip Select) pin on my Orange Pi Zero 3. I added overlays=spi-spidev to the /boot/armbianEnv.txt file, created my own dtbo file, and tried all possible methods suggested by ChatGPT. I've been struggling for two weeks with no success. I haven't been able to switch the CE1 pin to alt4 state; it only stays off, nothing else. Is it even possible to work with SPI on this board?
