Error: No STM32 target found - How to perform a discovery using Debug Authentication?

Hen1 · ‎2024-10-31

Hi,

I cannot connect to the NUCLEO-WB05KZ with the CubeProgrammer. Also tried the "Under Reset" option, I'm always getting the same error message:

" Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication"

How can I perform a discovery using Debug Authentication?

Hello @Hen1

Coul you please try to connect this board using those parameters (and all other parameters combinations even debug in low power mode):

Also, Check the jumper positions: JP2 ON, JP1 on USB_STLK [1-2].

Best Regards.

Perhaps focus on the power and connectivity. So jumpers or solder-bridges.

Hi Guys,

thanks for your comments! All jumpers were at their right position, but I additionally connected the JP1 jumper on the MB2032 MCU RF Board. I dont know if that was necessary?

After some trying with different settings and unchecking "Debug in Low Power Mode", I could connect to the MCU.

It seems it's working now!

Best Regards,
