Papaya5595 I've updated the RK3588 images in my test share to include newer iwlwifi firmware.
Thanks for the quick response. The new image no longer outputs video to my display but instead repeatedly flashes "HDMI 1 No Signal" which I interpret as difficulty completing a handshake.
Also noticed that the naming convention for the new image changed from "LibreELEC-RK3588.aarch64-12.90.1-rock-5b.img.gz" to "LibreELEC-ARMv8.aarch64-12.90.1-rock-5b.img.gz".
