Addon service doesn’t work with the latest official CoreELEC 9.2.4. No display at all. OLED Driver error is shown at the top of the screen at boot. I had to reactivate ODROID N2 SPI with the following SSH commands :
mount -o remount,rw /flash
fdtput -t s /flash/dtb.img /soc/cbus@ffd00000/spi@13000/spidev@0 status “okay”
fdtput -t s /flash/dtb.img /soc/cbus@ffd00000/spi@13000 status “okay”
reboot
And after that it works again.
