STM32L476 Nucleo - Cube IDE 1.12.0 - LL_PWR_IsActiveFlag_VOS endless loop

[EGi]

Cube IDE 1.12.0 Build 14980_2023_03_01_1550

OS: Windows 11 Pro 22H2 Build 22621.1413

Project using STM32L476 Nucleo board; low level only (no HAL used at all)

I've build my project IOC file using the previous version of Cube. When I open it, I have 3 options: continue / migrate /..

If I select "migrate" and generate code, the following statement appears in my systemclock init

while (LL_PWR_IsActiveFlag_VOS() == 0) { }

According to the source, this waits for the 10th bit in PWR_CR2 to become '1':

#define PWR_SR2_VOSF_Pos            (10U)

This bit seems to be reserved for STM32L471; so why is cube generating this in my project? Fact is: the code waits forever on the above while statement.

The best option I found so far is not to migrate my IOC file (unfortunately I did not find a way to attach it).

Differences in comparing the IOC files before and after the migration are only version info:

Keeping the IOC in the old version prevents generating the endless wait statement.
