[migrating form fex, how to disable hdmi, wifi and other]

Hi,

 

I am migrating from legacy 3.x kernel to bionic mainline 4.14 at OrangePi Zero 2 plus.

Previously there is a fex files to enable or disable some features such as onboard wifi, mali, hdmi and other. now I found no ways to disable it, overlays does not include this features. Is there any way to edit dtb files? or?

 

Thanks

Hi,

 

I trying to use UART 1 & UART 2 at OPi Zero 2 Plus with no success with armbian stable and ubuntu server. I test all combinations, of fex settings, turn off everything 

except required uarts, set uart_type = 2 and etc, and it did not connect. UART0 and UART3 works fine, but I need cts-rts lines from uart2 for hi speed (it's uart_type = 4, but I would like to start regular uart first).

tested with picocom, ft232 & pl2303

I use 8 & 10 pins for uart 1 and 11&13 for uart2 as described at http://linux-sunxi.org/Orange_Pi_Zero  

Is it correct pins?

 

Thanks
