Question: Odroid-c4 UART on pin-header
Hi,
I use an odroid-c4 with kirkstone release of meta-odroid. Kernel recipe linux-yocto is used.
I want to use Pins 8 and 10 of pin-header as UART to communicate with an external device.
The wiki describes how to do this with the official OS Release by adding an device-tree overlay. To check my hw-setup I did this and it worked fine.
Now I want to add the UART functionality to my yocto build. I tried to add the changes made in the device tree overlay to the kernel sources without success. My changes to the device-tree files are appended.
I guess there is something wrong with the pinmux, but I don't see where to change this.
Does anybody has an idea how to get the pin-header uart up and running on kirkstone release?
