@fpistm Does the ST Low Power Library work with the U5?

All my tests are passing, except I cannot achieve Low Power using the same sketch I use on both the Cygnet and Swan.

Do you see anything wrong with my board configuration that would prevent me from achieving low power?

As far as I remember, yes it works. Anyway it is possible that a bug or a missing configuration exist. Like for the USB part.
Hard to review your configuration as I do not have any information on the board. My review will mainly consist to ensure it has the good format and check some specific configurations.

Converted to aDRAFT PR.

I discovered a hardware bug during bring-up, and also just received word they are going to try a slightly different package to cost down the product.

I don't think this BSP will change much (if any), but I don't want to hurry and push support for a board that may not exist.

I should have new hardware soon, but not soon enough to hold the release.

Thanks for the feedback.
I close the PR.
We can reopen it if needed.
