Hello,

i use STM32F042C6 MCU and change SYSCFG MEM_MODE to 1 (System Flash memory mapped at 0x00000000) but always see Main Flash (0x08000000) data from address 0x00000000.

Also i try set 11 (Embedded SRAM mapped at 0x00000000) but unsuccess.

Also i try jump to system bootloader (0x1FFFC400) but MCU back to 0x08000000 vector after small delay (with USB connected).

Can anybody use software jump to system bootloader ?

Hi Mitek,

It seems that you haven't update the BOOT0 pin (it has to be set to 1).

Did you tried using the ST-Link Utility?
