application jump to system memory bootloader Hi,I have an stm32l43 connected as a USB device. Using the BOOT0 pin, I can start the built-in Bootloader and use DFU. Now I wish to jump to the BL without this Pin by a software jump.But with this jump, I only seem to reset the device (my code starts again like after a reset). It seems to me that the Bootloader starts, checks for valid code in flash and then streight jumps back there (as my firmware of course is valid code). How can I get the Bootloader staying active without using a boot pin or an option bit?here is my jump function for reference:void jump2STinternalBootloader(void){
void (*SysMemBootJump)(void);
