Update version 20191216 with kernel 5.5.
Added support for built-in WiFi.
Installed your build 201912120 LibreELEC-AML.arm-9.80-devel-20191220155508-6e9040d-amlgx.img.gz onto SD
Modified uEnv.ini and extlinux.conf to ensure pointing to correct dtb for my vim2 "meson-gxm-khadas-vim2.dtb"
Vim2 booted up into LibreELEC OK with following minor? warning message a start of 1st and subsequent boots
Build in WiFi "AP6359SA BCM4359" for my Vim2 Pro initially did not seem to be being recognised within LibreELEC settings, however when I physically connected LAN cable to VIM2 both wired and available wireless connections appeared.
Successful made connection to LAN as expected, then attempted to switch to available wireless connection(s).
1st attempted to switch connection to 5GHz band, entering password when requested etc. Upon entry of password and OK all available wireless connections disappeared from LibreELEC Settings list with no warning/error message. (recollect this as existing issue with LibreELEC settings, going into existing LAN connection as if to edit but select refresh option, finds and re-presents all available connections in list)
2nd attempted and successfully switched from LAN to 2.4Ghz band, great news
3rd attempted and successfully switched from 2.4Ghz to 5GHz band, great news
Switching/Making WiFi connections via the LibreELEC settings menu seemed a little flaky, but with persistence and additional attempts
Looking great for fully working WiFi on Vim2 Pro moving forward
