Okay, so i have a custom built image using the previous angstrom release (2014-xx) , that was running on kernel 3.8 and had no issue with the DTS or anything.
IT was actually quite straightforward to use, just adding a line in uEnv and the UART loaded.
Now, with the new Kernel 4, i’m not even getting that BB-UART1.dts file in the image !.
I made a custom recipe with a bbappend for the kernel, adding and building the BB-UART1.dts to a .dtb
I copied it to the new image under /lib/firmware/BB-UART1.dtbo
Now, on boot i’m seeing

but no sign of /dev/ttyO1 like in previous kernel.
i’m not seeing the HDMI “cape” like in previous kernel.

I must be missing SOMETHING, ANY help would be greatly appreciated. I’ll post a full working solution once this is up !
