BananaPi M2 HDMI resolution

[hanni76]

Hello, guys,

please help setup HDMI output to 480x320 in mainline kernel for BananaPi M2.

I am using 3.5inch HDMI display, it is working fine but my current resolution is too high. All attempts to change disp_mode in armbianEnv.txt didn't help.  

 

Thanks
