when i reset Read Out Protection from my bootloader (from bootloder sub-programm from RAM) i have a erased internal flash. Set ROP to 1 -> 0. All ok! But.. how i can back data write to first 4k?? first 2 pages is locked for RO!
But flash already is cleared! Data lost and all good. and why i still can not write to first blocks?
how i can reset RW protect from first 2 pages WITHOUT full reset (then RAM is corrupted and MCU is not bootable)?
It's need for restore my bootloader from RAM before BIG RESET or power off
