@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. |

I don't recommend to change this order.
If you need to debug, the correct way is to enable the "Optimize for debugging" in the Arduino IDE menu. Then debug and symbol is activated.
Else this mean by default binary is more fat.

Hard to check if all pin have an unique number as not ordered. Anyway I guess you have tested.
You can use this example to check if definition is correct:

| RCC_OscInitStruct.HSI48State = RCC_HSI48_ON; // Critical for USB |

Only of you left the CLK48 clk mux by default (HSI48).
As in your case you do not used PLL the only way is effectively HSI48 or maybe set MSK at 48000.
