Hi everyone! I have v25.8 rolling for radxa cubie a5e running Armbian Linux 6.14.0-rc1-dev-sun55iw3 runnig and it has only ttyS0 serial device. Due to device schematics it should be able to provide serail interfaces with RTS/CTS support UART4-7. Was anyone able to activate this devices? As I understand, I need an overlay .dtbo files. But those cannot be found anywhere in /boot. Also I can compile those overlays, but I need the correct .dts files.
