I can't find the way to use Bananapi M2U with this 80x600 HDMI 5" screen from: https://www.aliexpress.com/store/product/30fps-5-inch-LCD-HDMI-Touch-Screen-Display-TFT-LCD-Panel-Module-Shield-840-480-for/1534002_32314250806.html
I'm using 2017-08-24 - ubuntu 16.04.3 LTS Mate Desktop with support for BPI-M2 Ultra & BPI-M2 Berry kernel 3.10.107
That HDMI 5" screen works perfect with Raspberry Pi 3 using ubuntu mate too and Bananapi M2U works without no issues with my TV on 1080 resolution, but i can not find the way to use my small 5" HDMI screen with BananaPi M2U.
I have been trying to modify script.bin like you said on this post but i can not find the file script.bin anywhere. The /boot/ folder on root path ins empty. The only folder where the search returns this file is on usr/lib/u-boot/bananapi/bpi-r1/, not even on bpi-m2u folder. Can i just simple copy it?
Where is the uEnv.txt file? I can not find it too? What can i do?
By the way, on disp init configuration on fex guide from http://linux-sunxi.org there is not 800x600 resolution just 480, 576, 720 and 1080, so, what can be done to use 800x600?
