Can't program STM32N6570-DK on macOS?

[jmole]

Hi, I am trying to bring up some software on an STM32N6570-DK.

I'm able to upload example code from the STM32CubeIDE when the board is in DEV mode, e.g. when BOOT1 is set to 1. I followed the steps in this KB article: FSBL Explained 

However, I am unable to even connect to the board with STM32CubeProgrammer, even when in DEV mode. Here are the logs from STM32CubeProgrammer:

Port 0

I have tried a bunch of different options in the CLI as well, with no success.

I am also unable to find any loader scripts for N6 in the Programmer GUI:

And I found in the ROT demo code, MacOS is specifically listed as not supported.

So my questions:

1) Is it actually possible to program flash for this part on MacOS?

2) What kind of workflow do I need to set up to be able to write program code to flash and have it boot?

3) Is it possible (or recommended) to flash the BSEC-OTP to BSEC-Open in order to use the DVK like a normal flash MCU?

Hello @jmole

My suggestion for you is to upgrade to the latest STM32CubeProgrammer release (v2.20). STM32N6 has been introduced pretty recently and I doubt v2.13 has any support for it.
