I have been using STM32f207 to simulate anything before, there is no problem, system upgrade, consider 427 directly replace 207, the same board, 427jlink swd simulation prompt no cortex-m swd device found. I can’t find the problem, and then download the flash loader serial port. There is no model display in the target on the three pages, and the next step, the program will prompt address not allowed! I don’t know why?

This should solve it. Look at the picture.
I don't have F4, F2 movies, the second screenshot first delete programming arthxxxxx. Then add the corresponding flash.

First check if the pins are compatible, don’t burn it

These two are M3 and one is M4, the cores are different.
