STM32L072CZ - Jumping in DFU bootloader via software

[andre239955_stm1_stmicro]

Hello

I'm migrating my STM32F072 project to the STM32L072.

In my original project (F072) I can jump to the DFU bootloader by software via a function located before SystemInit.

I tried to convert this to be used by L072 by changing the address of bootloader program to 0x1ff00004 it's not working.

Is it due to the dual memory bank? Is there a way to get it working?

Thank-you

André

Jump on MCUs with detection firmware in flash not work or better say work , but default jump back to app if is detected in flash. One way is erase first memory sector before jump.

Second maybe as AN2606 pattern say 

try BFB2 0
