Seems to me it's an alternative to FreeRTOS et al. How it fits with MicroPython I have no idea other than they have a Zephyr port.Anyone care to give us a TLDR version of what Zephyr will do?
How, or if, it will enhance Micrcopython on the Pico/Pico2 ?
I took the opportunity of the late hour, and being unlikely to face local bandwidth contention, to follow the Getting Started Guide on my Pi 4B Raspberry Pi OS Bookworm 32-bit and it went as well as I had anticipated.
There was no 'gcc-multilib' or 'g++-multilib' available via 'apt' as it sort of suggests. My 'cmake', 'python' and 'dtc' met their minimum requirements.
It started well though the 'west update' took its time.
Then 'west packages pip --install' failed building dependencies for 'opencv-python-4.12.0.88.tar.gz'
Running 'west sdk install --help' as a prerequisite for the next step also failed. So I guess I'm not going any further unless I can get the packages it wants installed.
By that point it had consumed 7 GB of disk space - and that's without its SDK and all the packages it wants.
Update
Buried amongst the huge error message when 'west packages pip --install' failed was an "out of space" message. Unlikely on a 256GB SD Card with over 50% free. But my '/tmp' is a RAM disk so things can get unhappy when expecting large amounts of free '/tmp' space. With that fixed, onwards and upwards.
The 'west packages pip --install' then also took its time, especially building wheels, but did complete.
Then 'west sdk install -t arm-zephyr-eabi' downloads whatever it downloads but then fails to run it.
Three hours in and 7.7 GB used and I'm going to call it a night.
