I just got my NUCLEO-N657X0-Q board, since i have never used a stm32n6 board before, i decided to start from the stm32cubemx. I started my project from ST board, and created a simple test program for MDK-ARM project.
After I opened the project in the Keil v5 and rebuilt the whole program, with no warnings or errors, I found that i can't download my project to the board. It showed an error of "invalid rom table".
Then I decided to use the STM32CubeProgrammer to erase the whole chip, as I did before when developing stm32h7. I found that the flash size in the target information colums shows "null".
And when I used the full chip erase function, it shows: Mass erase operation failed. Please verify flash protection.
(p.s. I'm not a native English speaker, so pardon my poor grammer :( )
