BPI M3 issue Screen resolution+wifi issue

hello guys

i m playing for several days to try to configure my BPI-M3. Currently i have 2 issues: 1/ impossible to setup my screen resolution to 1920x1080.

  • i have try /boot/config manipulation => not working
  • i have play with uEnv.txt => not working
  • switch between the raspbian and ubuntu => same issue 2/ no wireless and BT

did someone use to have the same issue? or any idea where to look? it might be a motherboard issue, anybody experiment the same problem

many thanks in advance for your help…
