How STM32H747 dual-core M4 and M7 go into stop mode separately with the allocated peripheral DeInit and ReInit after wake up

Hi,

I want to set the dual-core MCU into stop mode respectively with allocated peripheral like UART/ADC/I2C/SPI/TIMER, DeInit the peripheral and disable the corresponding clock and start a lptimer to wake up the core before entering the stop mode, lptimer3 for wakeup M4, lptimer2 for wakeup M7, both core are running the freertos. However, the current still keep high at about 15mA, and sometimes the M4 can't wake up again if M4 and M7 go into stop mode together.

Can anyone encounter this issue or any solution to how to solve this issue will be appreciated
