No wireless network with nightly build on Odroid-C2

Official 9.0 is very unstable so I tried nightly. Had to dd on the SD card since placing at .update failed with could not mount .tmp/mnt/SYSTEM.

Anyway, nightly starts quickly but I neither get wired network nor wireless (Comfast Nano with RTL8188EUS, which I suspect to cause the trouble with stable release). Happy to support you with more information.

Skipped the wizard yesterday but run again with wired connection today and ethernet works. But wireless doesn't.

And obviously there is no module 8188eu to load.

It should be impossible to update from older LE (3.14 kernel) to nightly (mainline kernel) images .. I added an explicit check to detect this and abort:

LibreELEC.tv/canupdate.sh at master · LibreELEC/LibreELEC.tv · GitHub

I haven't been adding the realtek vendor-binary drivers to the LE master branch for Amlogic as I'm typically working on an rc kernel and these things break all the time, but I have enable most of the in-kernel drivers and rtl8188ee should support that device. Can you run "dmesg | paste" when using Ethernet (but with the WiFi device connected) and share the URL, it might me something simple like missing firmware.

Sorry for late response, didn't receive a reply notification for some reason.

Here is the system log http://ix.io/2opl and in case you need dmesg it's here

Put LibreELEC-AMLGX.arm-9.80.0.tar in /storage/.update/ and reboot, then run "dmesg | paste" and share the URL after it's rebooted (no need to copy/paste to pastebin). The image has a newer kernel with more realtek drivers enabled - and we can see if the card is detected. NB: If it is the card probably won't work due to missing firmware, but the log should should which firmware.

It looks like the rtl8188ee driver in the kernel is pci only, not usb, so nothing is showing up. This means you'd need the realtek vendor (not in kernel and breaks on every kernel update) driver .. and we've a long history of refusing to add them because they're a pain in the rear to maintain over time.
