STM32WB55CEUx custom board ble stack updating.

[HKIM.13]

Hi, I recently designed my own pcb board for STM32WB55CEUx MCU.

Then, during working with my board I got some problem at APP_BLE_Init() function

and the symptoms are exactly same with

this

STM32WB55 BLE Stack trouble on new hardware: https://community.st.com/s/question/0D50X0000B5IOp2SQG/stm32wb55-ble-stack-trouble-on-new-hardware

and this

STM32WB : Bug in FW_WB_V1.0.0: aci_gap_set_discoverable > hci_send_req > hci_cmd_resp_wait - wait infinitely for hci_cmd_resp_release after few connection/disconnection

https://community.st.com/s/question/0D50X0000AYqZ6mSQF/stm32wb-bug-in-fwwbv100-acigapsetdiscoverable-hcisendreq-hcicmdrespwait-wait-infinitely-for-hcicmdresprelease-after-few-connectiondisconnection

So, I think I should update the ble stack inside my mcu.

But, I can only find the examples for the nucleoboard, which has USB bootloader mode.

I only have ST-link interface in my custom board.

How can I update ble stack with only stlink? or is it impossible?

Every pins of STM32WB55CEUx is available in my custom pcb board and other normal functions except ble work normally.

Any other tips for my situation is welcomed.

FUS_STATE_ERR_UNKNOWN error message means the FUS is not activated. This can happen when you were just running your application SW. In that case the M0+ core is running the RF stack.

To wake it up, you have to issue the FUS get State command below.

 %PROG% -c port=SWD mode=UR -fusgetstate

With this command you switch the M0+ core to execute security services: The FUS will then execute any secure commands like fwdelete or fwupgrade.

Hmm. what next?

[Remi QUINTIN]

​Gosh!! I forgot this limitation on the SWD side. Note that this limitation will be removed in the future.

Ok just try the 2 commands below before sending the fwdelete command:

REM %PROG% -c port=swd -ob RDP=0xAA

REM %PROG% -c port=swd -rdu

Let me know then if it works.

It seems the SBRV value (0xF6) is pointing to an old version of the FUS.

To avoid any weird result, you should first upgrade the FUS to v1.0.2 and then to V1.1.0.

Please read the releases notes under directory STM32Cube_FW_WB_V1.10.0\Projects\STM32WB_Copro_Wireless_Binaries\STM32WB5x

Then select the stm32wb5x_FUS_fw_1_0_2.fin file to first upgrade the FUS to V1.0.2 and then use stm32wb5x_FUS_fw.bin file to upgrade the FUS to V1.1.0.

Those binaries are 6 sectors big (24KB). So you should load those binaries 6x 0x1000 below address 0x080D000 = 0x080CA0000.

What is strange is the value of the SFSA option byte: 0xD is not an expected value as it seems a FW had already been uploaded/programed. So It is not clear no me why you cannot erase it.

So, upgrade the FUS to its latest version and then try the fwfelete command again.

Could you tell what baord are you usning , The Nucleo board or your custom board?

[RLour.1]

This is a standard P-NUCLEO_WB55.

I have 5 and 7 jumpered together on CN7 and JP1 set to USB_MCU. RED LED4 lights. nothing appears on the PC indicating a serial port. That does not seem like a good thing.

Any more suggestions?

How to flash the Wireless Coprocessor Binary via USB (Command Line Interface)

• Inside the below procedure, the references to binaries name and install address are provided in the section Main Changes of this file.
• STEP 1: Use STM32CubeProgrammer
  • Version 2.0 or higher.
  • It gives access to Firmware Upgrade Service (FUS) (AN5185 : ST firmware upgrade services for STM32WB Series.) through Bootloader.
  • It is currently available as Command Line Interface (CLI) mode.
• STEP 2: Access to Bootloader USB Interface (system flash)
• Boot mode selected by Boot0 pin set to VDD
• For P-NUCLEO-WB55.Nucleo :
  • Jumper between CN7.5(VDD) and CN7.7(Boot0)
    • Power ON via USB_USER and Jumper JP1(USB_MCU)
• For P-NUCLEO-WB55.USBDongle :
  • Move switch SW2 to Boot0
    • Connect P-NUCLEO-WB55.USBDongle

There is no device to connect to do download anything.

I was able to program those images using the GUI STM32CubeProgrammer from the STLINK if. This address, 0x080CA000, works better than than 0x080CA0000. I still don't see a bootloader when BOOT0 is jumpered CN7.5 to CN7.7 and I am connected to the USER USB and JP1 in the USB_MCU position.

I am about ready to punt on this and switch to an NR52840
