P-NUCLEO-WB55 does not working on DFU mode

Hi, All,

​

I want to use CubeMon-RF to monitor the USB dongle of the P-NUCLEO-WB55.

According to the Manual : STM32CubeMonitor-RF software tool for wireless performance measurements,

The USB dongle must be monitored using the VCP DEVICE link, and it need to update Firmware to use the example : ble_transparent_mode_vcp.

​

To update the USB dongle's firmware, I must use STM32CubeProg tool.

According to the manual : STM32CubeProgrammer software description,

USB dongle must use DFU mode for Firmware update, and I install DFU driver follow the Chapter 1.2.4.

And set the DFU mode according to this web page https://visualgdb.com/tools/STM32WBUpdater/connecting/.

​

However, when the device is plugged into the PC, the Window Device Manager does not detect any device, and the USB dongle is the same as STM32WB Nucleo.

And Win7 is the same as Win10.

May I ask how to solve this?

​

Thanks. ​

​First check: Did you set the switch to the right position on the dongle=> opposite to the USB conector to set BOOT0 option byte to 1. This will set the USB in DFU mode.

Yes, I follow this web page https://visualgdb.com/tools/STM32WBUpdater/connecting/

to set BOOT0 option.

Then the CubeProgrammer tool should detect it when you select the USB mode​. Check the connection selecting the DFU mode and then click on the "connect" button.

In the end download the BLE_TransparentModeVCP_reference.hex binary at 0x08000000.

​Are you able to detect the Nucleo board in DFU mode?

​You can also check if the USB device is OK by opening the device manager.  The USB device should be recognized a Boot Loader. See picture.

Ok let's focus on the Nucleo Board. The document you read looks correct for a NUcleo board. So in the end your board should be configured like the picture below.

Beware to plug your USB wire in the right USB connector (not the ST LINK one).

Then You should se it with the CubeProgrammer tool.

For the Dongle, check the other picture

Then You should se it with the CubeProgrammer tool.

I've met this problem yesterday. For me the reason was the nSWBOOT0 option byte set to 0, so the hardware BOOT0 switch does no change. The only way to fix this is to use SWD to program nSWBOOT0 to 1

if the DFU Mode problem can't solved, May I use on board st-link of NUcleo board to update  Nucleo Board & USB Dongle both firmware? Have any document to descrip it?

Thanks a lot.

​It would be strange you get the same issue on both the nucloeo board and the dongle!!!

I dont know what to propose except using the JTAG/SWD port for the Nucleo board but this is of no use for the dongle.

Dear Remi,

​

I connect JP5 DEBUG pins of Nucleo Board to CN1 DEBUG pins of USB Dongle, then use STM32cubePorg tools to Update Firmware.

​

When I use the example firmware: ble_transparent_mode_vcp, and connect USB Dongle on STM32CubeMoniter-RF.

It show a waring message : "Device Under the test no responing COM port closed"

​

When I update back to demo example: BLE_p2pClient.

Then STM32cubePorg show a error message :"NO STM32 target found"

​

May I ask how to fix those problem?

​Indeed but when the USB DFU mode is used this nSWboot option byte is set to 1 with the command. Moreover the start of the issue was the USB device not detected.

Anyow it is worth the trial.

If you are able to connect with the JTAG/SWD port then you can either set nSWBOOT0 to 1 as the switch setting the PH3/BOOT0 pin is properly positionned.

launching the command STM32_Programmer_CLI.exe -c port=swd mode=UR -ob nSWboot0=1

or you can launch the command  STM32_Programmer_CLI.exe -c port=swd mode=UR -ob nSWboot0=0 nboot1=1 nboot0=1 regardless of  the PH3 BOOT0 pin.

or directly launch the complete command

STM32_Programmer_CLI.exe -c port=swd mode=UR -ob nSWboot0=0 nboot1=1 nboot0=1 -fwupgrade %FW% %ADDRESS%
