OK, regarding my issue with Kodi not starting.
On my 64GB card:
1. Clean install of LE Alpha 4 on Pi3. Works well.
2. Load my video db. Continues to work well.
3. Update to your build using 20160812 TAR, Pi3 boots but Kodi will not start.
4. Delete video DB file using WinSCP. Kodi starts again.
Thinking it might be the capacity of the card causing issues:
1. Clean install of LE Alpha 4 on Pi3 using 2GB card. Works well.
2. Load my video db. Continues to work well.
3. Update to your build using 20160812 TAR, Pi3 boots but Kodi will not start.
4. Delete video DB file using WinSCP. Kodi starts again.
So, it might be a Kodi bug but it appears tied to the version of Kodi that you currently have in the build and/or something with the patches/edits that you have made.
Has no one else had a similar issue on a pi3 with the 20160812 build?
EDIT: Same results with Pi2. Previous version of 20160806 did not have this issue.
