STM32L0 LOW POWER MODE

[Nbaşa.1]

Hi Everyone,

I use STM32L083 MCU. My code has two sections which are bootloader code and main code. 

Bootloader Code Start Address : 0x0800000

Main Code Start Address           : 0x08006400

I implemented low power mode in my main code and used  "HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI); " functions. If my main code start adress is 0x08006400, enter stop mode functions is not working and current consumption is around 1-2 mA. However, If I dont use bootloader and arrange main code start adress as 0x0800000, enter stop mode functions is working and current consumption is around 1-10 uA .

Can you provide a solution to make the first case work?

Best Regards,

Nuri

Hello @Nbaşa.1, 

Make sure that the vector table offset is correctly relocated to the start address of the main application 0x08006400

#define MAIN_APP_START_ADDRESS 0x08006400
SCB->VTOR = MAIN_APP_START_ADDRESS;
