Hi,

I would like to ask where I can download the STM32 Target Support Package files for older PLECS versions.

The current PLECS license I use is for version 4.5.6, however the files found on [STM32 Code Generation | Plexim](https://www.plexim.com/download/tsp_stm32) are for versions 4.6.1 or newer.

It seems that I would need the STM32 Target Support Package Version 1.0.

I am sorry if I am missing something obvious here, but I cannot seem to find where I can download these files from.

Thank you in advance,

---

You can access previous releases by modifying the URL of the \*.zip download. The zip archives are named st\_stm32\_1.x.y\_win.zip where x is the major version and y the minor (bugfix) version. The latest bug-fix release for each major version is [st\_stm32\_1.1.1\_win.zip](http://www.plexim.com/sites/default/files/packages/st_stm32_1.1.1_win.zip)

The hosting of these files is subject to change, but you can always reach out to [support@plexim.com](mailto:support@plexim.com) if you encounter this in the future.

Also note that with a permanent license you are entitled to all bugfixes associated with the last major release when your license expired. If your license works for 4.5.6, then it will also support up to PLECS 4.5.9, and therefore the 1.1.1 release of the STM 32 TSP.
