Hi,
I have problem to enable multiboot on TV BOX Evolveo H8 ( https://www.evolveo.com/en/android-box-h8 ) Amlogic S912 3gb Ram 16gb rom 1gbit WiFI LTM8830
CoreElec starts from SD card without any problems.
Box don't have Backup&Update app (only OTA update) so I try to use dedicated reset button and adb reboot update but always finished with recovery menu and massage " Support Api.3 Recovery is listening adb sideload... Waiting adb sideload command.. E: cannot load volume /misc!"
I tried differnt sd cards (32gb/64gb) and dtb files without any success with balbes armbian compilation.
Some photos of box board : https://photos.app.goo.gl/8wmR329H1Qgy99rJ9
On other box with amlogic S912 I start armbian without any probles (box has Update&Backup App)
Mayby someone has idea what I doing wrong ?
