I have tried to measurement the current consumption in standby mode but it is too high. I am using the example "PWR_STANDBY_RTC" listed in AN5315, STM32Cube firmware examples for STM32G4 Series which should work in Nucleo Board G474RE. The values I obtained are in the range of 250 microampers which are quite far from the listed in the datasheet which are around 1.4 [mA]. To measure the current I use a X Nucleo LPM01A.
Has anybody worked with that example and obtained the reported values from the datasheet?
Does anybody know if it could be a kind of "bug" in the microcontroller?. Please read: https://community.st.com/t5/stm32-mcus-embedded-software/how-to-enter-standby-or-shutdown-mode-on-stm32/m-p/145849
Following I attach some images.
Thanks in advance!
