STM32N6570-DK Debug Issue

[Okeskin]

Hi Everyone,

I've been working on the N6 kit for a while. Initially, I was able to debug it, albeit with difficulty. However, in my latest attempts, I haven't been able to. I've updated Stlink, the IDE, and CubeProgrammer. I continue to receive the error below. I'm following all the instructions in the Readme. Also, as I mentioned, I've been able to debug it without any problems for about a month.

I know that debugging MCUs with external flash drives requires some special considerations. However, when they suddenly stop working after booting, it really makes the development process quite tedious. What should I check? I've eliminated things like the USB cable.

Hello @Okeskin;

Are you using the STM32CubeN6 firmware example? Are you experiencing the same issue with a firmware example?

I recommend you referring to How to debug STM32N6 using STM32CubeIDE - STMicroelectronics Community article and follow the steps to debug code from external serial flash. This tutorial is a comprehensive guide for debugging code from external serial flash on the STM32N6. It covers: setting up the environment, configuring the debugger, and validating the setup.

I hope this help you!

Thank you.
