pyOCD Most ST MCUs are missing

It seems that most ST's MCUs are missing. Only STM32L1 and STM32F3 MCUs are available. What is going on?

I am seeing the same thing.

I'm using pyocd 0.36.0 and cmsis-pack-manager 0.5.3.

I can't install most ST packs on my Windows 10 and 11 machines. I'm looking for stm32h5. It did work on my linux machine, but took a while.

Also, I was able to install some packs from other vendors on Windows, e.g. pyocd pack install samv70 worked.

I understand that pyocd defers to cmsis-pack-manager for handling cmsis packages. If I use run the command `pack-manager print-cache-dir', the returned directory doesn't exist on Windows. On linux, it is full of *.pdsc files.

It appears that pyocd pack update does not consistently cache all available packs. Some packs may be missing randomly. Probably due to a server-side rate limit.

I could reproduce both successful complete update and successful but incomplete update, as of today.

You can manually complement missing packs. See this comment for details. https://github.com/pyocd/pyOCD/issues/1602#issuecomment-1871118285
