NUCLEO-N657X0-Q: Connection lost during ST-Link Upgrade

Hello,

I am currently experiencing some difficulties using the NUCLEO-N657X0-Q board.

I am using STLinkUpgrade v3.17.10, and the device ID is correctly recognized as 003500244142501120353451, as shown in the attached image.

However, when I click "Open in update mode," the PWR_STATUS LED on the Nucleo board turns off and the connection is dropped.

I am not sure if this specific update is critical for operation, but I would greatly appreciate any guidance or help to resolve this issue.

@KDJEM.1 Thank you for the reply.

 

I didn't have a standalone STM32CubeProgrammer installed. I only had v2.2.3 (included with CubeIDE) and v2.2.4 (installed via update) together within the plugins folder.

 

I tried it in another environment where the STM32CubeProgrammer GUI is installed, and it solved the problem!

Thank you for your help!
