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 :( )
Hello @OliverLyu and welcome to the community;
Which STM32CubeProgrammer version are you using?
Could you please try with STM32CubeProgrammer2.19.0 version and click on full chip erase as shown in the below figure.
Please let me know if the issue is solved or not?
Thank you.
