Error: No STM32 target found! If your product embeds Debug Authentication In stm32 Programmer

[BSang]

Hi Everybody,

I try to flash my firmware into NUCLEO-STM32F410CBT6, 

first, I didn't remove CN2 Jumpers for nucleo ST-link V2.

and then, select nucelo board in cube32Programmer

after that, click connect button, it works well.

but, I want to flash program to use ST-Link V2, not nucleo board.

In the datasheet for ST-link V2, 2x10 20pin connector.

To use JTag or SWD flash, at lease VDD, JTMS, JTCK, GND, JTDO, NRST are need.

So, I connect wire to St-link V2 pin to Nucleo Board, it is not work.

How can I do that?

Thanks

I don't quite understand what you want to achieve. Do you have a separate ST-LINK/V2 with which you want to programme the target (STM32F410) on the NUCLEO, i.e. instead of the integrated ST-LINK/V2-1?

Hi, I want to flash using external ST-Link/V2, not using nucleo internal ST-LINK/V2 module like this.

With the current setup, you have two ST-LINKs in parallel, which of course cannot work. You must remove the two jumpers from CN2 so that the embedded ST-LINK/V2-1 is disconnected from the target.

BTW: there is no NUCLEO with STM32F410CBT6, you probably mean the NUCLEO-STM32F410RB?

Please note that the target currently gets its HSE from the MCO of the ST-LINK/V2-1. If you want the target to be independent and have its own HSE, you must:

• Open SB50
• Close R35 and R37 or fit them with 0-ohm resistors
• Fit X3, C33 and C34

(see also the schematics, page 3)
