Where is the "Debug Authentication" ?

[MQi.1]

I used a MB2032-WB09-B02 on MB1801D for several times, flash in CubeIDE was always OK, though debug prompted error read data every time, then the next day when I used it again, it didn't work, I couldn't flash image into neither in IDE nor Prog, the prompt:

my question is: how to discovery using Debug Authentication?

Hello @MQi.1 ,

Check the solder-bridges and jumpers positions (JP2 ON, JP1 on USB_STLK [1-2] on the MB1801 board.)

Switch SW1 should be on the 3V3 power supply (switch on position [1-2]) on the MB1801 board.

Make sure to follow the settings described in the UM3345 STM32WB09 Nucleo-64 board (MB1801 and MB2032) in Getting started section and Table 12. Solder bridges for MB1801.

In page 9 of "UM3345 STM32WB09 Nucleo-64 board (MB1801 and MB2032)", when MB2032 is upper (Type-C under Reset key), JP1 is on [1, ?], this the default location when I got this board kit (MB1801 + MB2032), while the note is "5V_STLK" not "USB_STLK", and there is also a "VBUS_STLK" on right side, is that right ? I mean is there an error in UM3345 ? Since when I could flash before, I have never find the board before Bluetooth pairing stably, I changed the TX power to MAX (0x1F) as it was told here - page 167 of AN5207 (Tx power level).

I identified the settings described in UM3345, the first 2 items is OK, for item 3 and 5, I didn't use ST Bluetooth® Low Energy sensor mobile application on a Bluetooth® Low Energy compatible mobile device from the App Store or Google Play, I just turn on Bluetooth on the mobile phone and want to find the WB09KE, did this matter?

On page 39 of UM3345:

Jumper connects 2 and 1: The bootloader is activated and the user can download a new application.

I got this:

Hi @MQi.1 

Please update and try with the latest release of STM32CubeProgrammer.

Check that you are using the pins that are supported by the bootloader, as described in AN2606 : STM32 microcontroller system memory boot mode - Application note.

Try to mass erase the device with STM32CubeProgrammer before debug.

When I changed into other windows PC, it was shown as an USB driver with label: "NOD_WB09KE", and there are 3 files in it:

and the content of "FAIL.TXT":

The interface firmware FAILED to reset/halt the target MCU

What does that mean?

[MQi.1]

I saw on page 409 of AN2606:

Should I use a USB-TTL or the ST-Link V3 on MB1801D would be shifted to UART configuration when use it in boot mode?

Exactly the same here. How to solve this issue? It seems that is needed other pin in some "state" than only keeping PA10 high under and after reset to start uart bootloader on STM32WB09xxx. But what?
