Hello people,
For boot problems with BPi M3 i noticed sth. about SD cards.
Please make sure that your sd card is OK and healthly.
When we start testing BPi M3 we also experienced some problems with booting. Problem was with broken sd card. We replaced it with new one, for example SanDisk 32 GB and it works fine.
But i could confirm that i have a problem to run latest Android image (from 2017-01-11) //image don't boot//.
Anyway - all other images provided by SinoVoip seems to work fine.
If you use dd command on Linux then it should write image on your sd card properly.
Warm regards
Pawel
