no and no.

but you can make your own bootloader and keep it protected in a section of flash. too bad ST won't release the source of their bootloader, it'd make things easier for you. they do provide DFU code to flash via USB (but if your code must be secure, I wouldn't use it; it might have security issues in the form of exploitable bugs).

1. it is possible to jump into the boot loader from your application. So you do not need to modify the BOOT0/BOOT1 pins.

It's possible with a jump to 0x1FFF F000?

Are there configurations before jump?

Hi,

You are right. We finally failed to use the remapped USART1 for the boot loader.

Has anyone there implent his own boot loader?
