Rename STM32L4x1 VDDUSB pin into VDD #2463
Conversation
The STM32L4x1 SoC do not have USB support and thus no VDDUSB pin. A simple VDD pin is used instead. This probably comes from a copy and paste issue from other another SoC in the family.

@aurel32 thanks for pointing this. The modification break existing design and can be merge only for the next major release (V6). I wuld suggest to stack also the VSS pins at the same time. Joel |

In the meantime, would that work simply replacing the VDDUSB pin by a VDD one without grouping them? Designs that do not place the "VDDUSB" pin connected to the "VDD" ones are broken anyway. |

If you want yes we can separate in two pull request and first fix the name of the pin only, with no move. This can be merged now without waiting V6. |

I believe all of these symbols are auto-generate by a script at https://github.com/KiCad/kicad-library-utils/tree/master/schlib/autogen/stm32. It seems the URL format is changed and I didn't try to track down if this particular symbol is, but fixing the script is the best solution if that is the case. FYI, the script was written by @Ratfink . |
|
Good information from @evanshultz ! If it is, the generator should be updated to generate the symbols again. |
|
We are currently discussing of a new scripting method for all MCU at #3059, the STM generator will no more be up to date if the goal is achieved, I propose to merge the pull request right now for this fix. |

@aurel32 no comment on the VDDUSB pins, just one request if you have time to do it: several symbols have KLC error S5.2 because of wrong fp filter. If you have not the time to do it I will merge your PR like that because it's not a regression. Thanks |

Not sure the author will respond to the previous question so merging right now. |
