PWR_STANDBY_RTC example in Nucleo Board G474RE

[Magera]

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 [microA]. 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!

Hello @Magera,

I have tested the PWR_STANDBY_RTC example on the NUCLEO-G474RE board (Link: here) and it works correctly on my setup.

To help us assist you better, could you please provide the STM32Cube firmware version and the product revision of your Nucleo G474RE board?

Thanks for your contribution.

Hello Dor_RH, 

thaks for answering, I am not sure if I found the data you me asked for.

The example is inside of the folder STM32Cube_FW_G4_V1.6.1 and in my board one sticker contains NUCLEO-G474RE. NUG474RE$AT4. And on the back MB1367-G474RE-C044, A230501799. If it hepls I am using STMCubeIDE version 1.19.0

Thanks
