I can jump without problem inside the main memory and boot a second software. Can I do the same thing with the SRAM1? I've copied data from main memory (0x0802000 to SRAM1: 0x20001000), but I can't jump to that address

Which part?

You can run code from RAM at 0x20000000+ typically

You can't jump to 0x20001000, for example, as it is EVEN, and executable THUMB code is referenced at ODD addresses.

The Vector Table contains a list of addresses, and is not inherently executable, the addresses in the list are also absolute so if moved need to be relocated appropriately.
