(Essam Salah) #1

Hey folks,

I thought to share the problem I am having here, may be some could help me out …

I got the BPI-M2M and the BPI 7 inch touch screen, my BPI-M2M is connected to my mac via USB2UART dongle, burned Android on SD Card and the board have booted but the screen is not working.

Here is the boot log as it appear on my terminal:
