I want to compile RT Kernel for Tinkerboard2

[Suleyman Poyraz 0]

Hello.
I need RT linux for my project. So, I'm trying to compile a base image for Tinkerboard2 with RT patches. As I look to TinkerBoard2/kernel (github.com) , it is 4.19.193 but appling related patch https://cdn.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patch-4.19.193-rt81.patch.xz is not succeed. 

look output: patch.log

 

When I pass the this step, I got error:

```

Is there any way to compile RT linux kernel or build newer kernel releases with RT Patches?

And also I want to compile image for Tinkerboard2. As I understand, I need to use TinkerBoard2/debian (github.com) bug at the end of the 

./mk-base-debian.sh

command. I take this error:

```

Failed to run livebuild, please check your network connection.

```
