@JHöfl.1 We have the option bytes set to prefer the nBOOT0 bit over the legacy BOOT0 pin. Our device shares the BOOT0 pin with the SWCLK pin, would you recommend a pull-down on this?

@gbm , @Konami Thanks very much for this - we can now enter the bootloader.Last question, when programming with STM32CubeProgrammer, with the 'Run after programming' option set, would you expect the program to start automatically after completion?

@gbm We're using Keil for this project - do you know how to check the instructions here? In any case, we've tried setting -O2 optimization and it has had no effect.If it helps, this is the state of the registers after the jump:When we entered the boo...

Hi @Konami ,That's good to hear! We've implemented the code as set out by @gbm earlier in this post, and have also added the memory re-map, see below: #define BOOTLOADER_ADDR 0x1FFF0000 struct boot_vectable { uint32_t Initial_SP; void (*Reset_Handl...
