STM32MPU135F-DK STM32CubeProgrammer Error: Cannot Access Port!!!

[BGibs]

Hello,

 I recently purchased the STM32MPU135F-DK and is having an issue with connecting to the discovery kit using the STM32CubeProgrammer Version 2.16.0.  It looks like when i try to connect the STM32MPU135F-DK, I get this "Cannot Access Port 0!!!" (Please see picture attached). I have never seen this issue before with any of my STM32 discovery kits.

Can you please tell me how to fix this issue?

HI @BGibs 

unlike STM32 MCUs, the STM32 MPUs (all STM32MPx series) cannot be programmed using STLINK. With CubeProgramer, you should use USB (or UART in some extend) to populate the target flash.

STLINK is only usable to debug the platform.

Please have a look to
