I have access the MCU using only SWD pins (No ISP accsess) because of the BGA package.  I would like to enable the code read protection level 1 (CRP1) and download the firmware. However, CRP1 disables the SWD. Can I complete the first (one shot) firmware (CRP1 enabled) download using SWD? In the crp.h it says "You will need UART connectivity and FlashMagic (flashmagictool.com) to reverse this. Don't even try this without these tools; most likely the SWD flash programming will not even complete".

I need an urgent help.
