Da Flex all of those 'errors' are normal and harmless on Amlogic hardware. The bootloader being un-aligned is just a quirk of the platform. Amlogic hardware has no separate power regulators on the Mali chip (as the SoC was designed not to require them) so the kernel (correctly) reports they are not found on every Amlogic board. Broadcom WiFi clm_blob files are board-specific tuning files and the only boards in LE's entire line-up that have them are RPi boards, so all other ARM SoC devices with Broadcom WiFi chips (Amlogic, Allwinner, Rockchip, etc.) also fail to load them and report that error.

mr-bledi The one issue that I can see in logs is this:

2024-07-19 10:13:58.522 T:904      info <general>: [WHITELIST] Searching the whitelist for: width: 1920, height: 1080, fps: 59.940, 3D: false

The log is not a debug log (so missing a load of useful info) .. but that shows 1080p 59.94 VP9 media being upscaled to 4K@60 which Kodi will struggle with on an ARM SoC device. Kodi needs to scale the media 4x and also handle the mismatched refresh rate.

However that shows an underlying issue with fractional rates (they are all missing):

I've previously created https://patchwork.freedesktop.org/patch/573860/ which is now merged in the kernel. However including that patch now seems to cause fractional rates to go missing - If I revert that kernel change 23.976, 29.97, 59.94 rates are restored to the list of detected resolutions. However that won't help with playback, because then the original problem with 59.94 rates reported in the patch will resurrect itself. I'd guess that something else changed in the kernel, but right now I don't see anything obvious, and I don't have free time to bisect and find the breaking change at the moment.
