Hi,

I'm using STM32L1, and I would like to read out the option bytes values to make sure I was able to lock the read option of the memory.

What is the quickest way to do so ?

Thank you.

Hi Wonder Cakes!

if you are using hal libraies, check your Cube example\Flash\Flash_WriteProtection Folders,

It goes like this

FLASH_OBProgramInitTypeDef OptionsBytesStruct;

...

HAL_FLASH_Unlock(); HAL_FLASH_OB_Unlock(); HAL_FLASHEx_OBGetConfig(&OptionsBytesStruct);

Is that what you want?
