@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. |
| RCC_OscInitStruct.MSIState = RCC_MSI_ON; | ||
| RCC_OscInitStruct.MSIClockRange = RCC_MSIRANGE_0; // 100 kHz initially (will be overridden later) | ||
| RCC_OscInitStruct.MSICalibrationValue = RCC_MSICALIBRATION_DEFAULT; | ||
| RCC_OscInitStruct.HSI48State = RCC_HSI48_ON; // Critical for USB |
There was a problem hiding this comment.
Only if 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.

Converted to a DRAFT 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. |
