Saurabh Posted March 9, 2020 Posted March 9, 2020 Hi, can anyone let me know if we can enable a UART port from a DTB file? Means like compile DTB to DTS, make changes and then again recompile it to a DTB like we do in the script.bin file of legacy kernel. Earlier I have used to mention "overlays=uart1 uart2" in the armbianEnv.txt file but, this didn't work for me .

It should have worked ... Did you look at boot time if overlays produced errors ? Did you look at "dmesg | grep tty" ?
Saurabh Posted March 19, 2020 Author Posted March 19, 2020 Yeah I did, I downloaded the latest image(5.4 Kernel) and it worked. Still, I do not know why it didn't work in 4.19 Kernel.
