I tried to add support for custom SoC and custom board without
adding to zephyr tree and I could do that. I am able to compile
hello_world by passing needed command line options to cmake
(SOC_ROOT, BOARD_ROOT, DTS_APP_INCLUDE). I maintained similar
directory structure as zephyr in my work area.
Now I needed to add drivers support. How do I add drivers support
without adding them to zephyr tree?
I tried creating similar structure like drivers/i2c folder in my work area and added Kconfig.mysoc, CMakeLists.txt and my_i2c_driver.c. I have also created Kconfig and CMakeLists.txt under drivers folder also.
At my work area root level also, I have created CMakeLists.txt and Kconfig. I could enable config options by passing KCONFIG_ROOT to work area root.
Now the problem is with CMakeLists.txt. I tried to include my
work area root CMakeLists.txt in samples and it didn't work.
What is the recommended way to develop drivers for custom soc without adding to zephyr tree?Thanks,
