I would like to run the STM32L011K4 (Nucleo kit) in low power mode for 10ms then put it in STOP mode with a wake-up via the RTC 90ms later.
Step 1: Operation in RUN mode all the time (10ms +90ms), the consumed current is about 54µA (57µA in DBG).
Step 2: same as step 1 but in LP-RUN, the current consumed is around 35µA (37µA in DBG).
Step 3: operation in RUN mode for 10ms then STOP for 90ms, the current consumed is approximately 38 to 40µA (40 to 42µA in DBG).
Step 4: operation in LP-RUN mode for 10ms then STOP for 90ms, the current consumed is approximately 10 to 15µA but in DBG mode the message "Target is not responding, retrying ..." is obtained.
Why this message when the function "HAL_DBGMCU_DBG_EnableLowPowerConfig(DBGMCU_STOP)" is called before?
