Hi everyone,

is it possible to enter the bootmode without setting the Boot0/1-pins with an external switch?

Yes, you can change the zero mapping, and you can also jump to it.

What you mean with Zero-Mapping?

One of the primary roles of the BOOT0/1 pins is to define what memory (FLASH, ROM, RAM) is mapped/shadowed at address zero.

ie FLASH at 0x00000000 and 0x08000000, the Cortex-M3 expects the boot memory to be at zero.
