Create a recipe for the Real TTY kernel
Use the following commands to create a recipe for installing Real TTY kernel to the target platform.
1.
Create a directory recipes-kernel in meta-moxa:
$ cd /home/user/poky
$ mkdir meta-moxa/recipes-kernel
2.
The simplest way is to copy and modify from a hello example, which is available in the Yocto source
code:
$ cp -r ./meta-skeleton/recipes-kernel/hello-mod ./meta-
moxa/recipes-kernel
The content of meta-moxa now is listed below:
$ tree meta-moxa

└──
hello-mod_0.1.bb
3.
Delete the unnecessary files in hello-mod. Rename the hello-mod.
$ cd ./meta-moxa/recipes-kernel
$ rm ./hello-mod/files/COPYING
$ rm ./hello-mod/files/hello.c
$ mv ./hello-mod/hello-mod_0.1.bb ./hello-mod/realtty-kernel_0.1.bb
$ mv ./hello-mod realtty-kernel
4.
Extract the Real TTY source code in /moxa. Copy the following files into hello-mod:
$ cp /moxa/COPYING-GPL.TXT ./realtty-kernel/files/
$ cp /moxa/npreal2.c ./realtty-kernel/files/
$ cp /moxa/npreal2.h ./realtty-kernel/files/
$ cp /moxa/np_ver.h ./realtty-kernel/files/
5.
