Hi,The LSI clock speed changes by 200..300Hz when the voltage regulator switches (ie., when the MCU enters stop 1 mode). Since I calibrate this clock to the 32MHz HSE in running mode (with the normal voltage regulator), it causes an inaccuracy in sto...

Hi Waclawek,Yes, it's clear that the LSI is unstable, however, if calibrated often enough to the HSE (such as every minute or on temperature changes, etc.) a reasonable accuracy is achieved: In fact, it works well and highly accurate until I switch t...

Hi Sarra,Thank you for replying.I calibrate the LSI to HSE, however that needs the normal voltage regulator to be active. Then, when the MCU goes to stop 1, the low power voltage regulator gets activated and the LSI frequency changes (possibly due to...

Hi,The effect is exactly the same with STM32CubeIDE 1.8 & 1.9.Yours, Daniel

LSI clock stability vs. normal and low power voltage regulator

CubeIDE is supplied by STM32WLEPack rel. 1.2 -- but on Github still Rel. 1.1 is provided. Is there another repository that is kept up to date or can you please update the Github version? Thank you!

Hi, created a new project (for STM32WLE5), added all sources files as linked resources. Compiles fine, but rebuild is not possible without manually deleting the build folders (e.g. Debug), otherwise I get an error (see below):
