- Audio support is currently missing
The 26 pin headers on Orange Pi Zero3 provides the following interfaces:-
- 3 I2C
- 2 UARTS
- 2 PWM
- 1 SPDIF
- 1 I2S
- and 1 SPI with 2 CS pins.
The pwm, spdif and i2s support is not there in kernel yet and hence overlays for them are not yet available. We have added overlays for i2c and uart. The spidev1_0 and spidev1_1 needs some editing and will be fixed in the future. When using the overlays, user should make sure they don’t enable overlay for features that use the same pin as this can cause conflict and either only one of the conflicting overlays or none of conflicting overlays will work. Its easy to fix it though as one can just disable it again from armbian-config.
- Images for non LTS version can be downloaded here
- Legacy kernel based images are using improved and updated stock kernel with proprietary boot loader. Sometimes hangs on reboot.
- Mainline kernel does not support wireless, HDMI, … It is useful for server case scenarios.
- USB3 sometimes doesn’t detect high-speed devices properly
