Since I have not previously done this kind of work, you will need an instruction How to install these patches on the specified system
but, I will be able to check the operation of RTS and CTS signals
Hi All!
OS - ARMBIAN 5.38 stable Debian GNU/Linux 9 (stretch) 4.14.18-sunxi
OPI Zero.
armbianEnv.txt :
overlay_prefix=sun8i-h3
overlays=uart2
param_uart2_rtscts=1
RTS CTS don't work
I check the work of the logical analyzer. The line RTS does not change the voltage during the request for data transmission. This is necessary for me to connect the MAX485 chip to UART2 OPI Zero.
