Hello,
I am using STM32CubeAI Studio with the NUCLEO-N657X0-Q board.
Board:
- STM32N657X0H3Q
- NUCLEO-N657X0-Q
Tools:
- STM32CubeIDE 2.1.1
- STM32CubeMX 6.17.0
- STM32CubeProgrammer 2.22.0
- STM32CubeAI Studio
I generated a project from STM32CubeAI Studio and tried to run/debug it, but flashing always fails.
Main error:
Error finishing flash operation
failed to erase memory
Load failed
Detailed log:
Erasing external memory sectors [16 19]
Error: failed to erase memory
Additional information:
ST-LINK FW : V3J17M10
Board : NUCLEO-N657X0-Q
Device name : STM32N657
SWD freq : 8000 KHz
Connect mode: Hot Plug
Reset mode : Software reset
I already tried:
- Full chip erase using STM32CubeProgrammer
- Under Reset mode
- Lower SWD frequency (4000 / 2000)
- Regenerating project
- Rebuilding FSBL and Application
- Reconnecting USB power
- Creating a new CubeAI Studio project
However, the same error still occurs.
Could this be related to:
- external XSPI flash loader,
- STM32CubeIDE version compatibility,
- CubeAI Studio generated partition layout,
- or STM32N6 external memory initialization?
I would appreciate any guidance.
Thank you.
