thanks a lot for the info and sry for my bad english ^^"
ir-remote is working but you must configure it over ssh with ir-keytable.
my only real problem is that i cannot set a static ip adress. after reboot it is back to dhcp.
wifi and bluetooth not working.
for internal install with multitool from armbian for tvbox with rk3318/3328 a bit tricky.
my method was:
(windows 10, balena etcher, usbimager, 7zip)
1. burn LibreELEC-RK3328.arm-11.0.1-a1.img.gz on sdcard or usb stick smaller than the internal emmc from the box.
(my usb-stick was 2gb)
2. replace the dtb.
3. create an image from the sdcard/usb-stick with usbimager.( it should be on the desktop *.dd)
4. rename the file to LibreELEC-RK3328.arm-11.0.1-a1.img
5. gzip the file with 7zip.
6. now you have the image. copy it on to your multitool sdcard under image.
7. now to your tvbox. insert multitool sdcard and create a backup from your internal emmc.
8. erase th internal emmc.
9. burn your createt image.
10. after that power off, remove the sdcard and boot.
