System: Raspberry Pi 4B, rasberry PI OS Trixie Id like to point a couple of errors in the initial post in case someone gets stuck just like i did. When cherry-picking, use the command `git cherry-pick b37a3f6bb..morse/mm/rpi-6.12.21/1.16.x` The `morse` is missing from the instructions. In addition to this, there seem to be some issues with the `morse-driver `, which fails to build because function declarations have inputs of ints while the definitions have inputs of an enum. While i fixed this for `morse_log_is_enabled` in `debug.h`, there are more issues in the `morse_firmware_init` function in `firmware.h`. Here, it does not seem to be solvable by just changing the `uint` to `enum morse_config_test_mode` and including `morse.h`, because then I get the error ```auto morse_driver/firmware.h:150:50: error: ‘enum morse_config_test_mode’ declared inside parameter list will not be visible outside of this definition or declaration [-Werror] 150 | int morse_firmware_init(struct morse *mors, enum morse_config_test_mode test_mode); ``` This is happening because the compiler is treating warnings as errors as specified in the makefile, but before I go ahead and start making changes to the code, I want to ask if anyone has been able to compile this just based off the the instructions and if I am doing anything wrong --- _[View the full topic](https://community.morsemicro.com/t/build-thread-halow-for-raspberry-pi-os/1124)._
