Unable to start FUS

[ATaba.1]

I am using the STM32WB55RG MCU, Bluetooth feature with stack version 1.13.0 and FUS version 1.2.0. Everything was working normal until I tried doing the firmware upgrade of stack from v12.0 to v13.0. I am not able to perform FUS related operations. The version reading shows 0.0.0 for FUS. And following is the log when I hit "Start FUS"

 11:09:47 : Warning: Option Byte: nSWboot0, value: 0x0, was not modified.

Following is OB info attached. Cube programmer version I am using is : v2.9.0

What could be the issue, please let me know how to resolve FUS and start wireless stack successfully ?

Thanks.

Sorry about that, here it is:

Hello,

Load this diagnostic binary in M4 which display Wireless Stack and FUS version on debug trace and allow to perform some action:

• Press SW1 to delete the installed Wireless Stack
• Press SW2 to install the CPU2 update (either FUS or Wireless Stack), file already in flash memory
• Press SW3 to switch between FUS and Wireless Stack

In your case, FUS is running, so try to delete the installed Wireless Stack and then with STM32CubeProgrammer install the stack with address indicated in release notes.

Best Regards

Hi @Remy ISSALYS​ ,

Thank you for the binary. I have the following questions regarding how to use this binary:

• How to load it onto M4?
• Can I use CubeProgrammer to load this? If yes, what is the address I should flash it at?
• Where is the SW1, SW2 or SW3 located?
• Are you referring to switches on some board? I am currently using the STM32WB55RG chip on a custom board.

Thank you,

Hello,

You can use STM32CubeProgrammer to load the binary into M4 at 0x08000000. Yes, I refers to P-NUCLEO-WB55 board. So, I think you can try this binary only to see wireless stack and FUS version.

Okay, if I understand correctly, I can flash this via programmer at 0x08000000 and hit the "Read FUS Info" button to read FUS and stack versions?

Can I use the same binary and try deleting the wireless stack through cube programmer by hitting "Firmware Delete" button?

Thanks

[Remy ISSALYS]

You can flash the binary via STM32CubeProgrammer in "Erasing and Programming" window at 0x08000000. When it's done, if you are able to connect your board to a HyperTerminal (TeraTerm for example), you have some logs which displayed FUS and Wireless Stack version like this:

You can also see if the FUS is runnning or if WS is running.

Others solution with STM32CubeProgrammer, try to delete Wireless Stack with "Firmware Delete" button.

I have similar problem, I have old Nucleo Board and new one, on the old one I can't do wireless stack update and FUS update, and even examples with BLE don't work.

I flashed your binary and don't see any information on VCP i TeraTerm, tried 115200 and 9600 baudrate.
What can I do to make it work? Please help me.

Just missing the ESE and SBRV value.

For the old board, you may need to update the FUS version.

Can you try to read the FUS version via the USB port in DFU mode at address 0x0x20030030?

Use cube programmer or the command in line below:

STM32_Programmer_CLI.exe -c port=usb1 -r32 0x20030030 1

Hello,

According to your screenshot, SBRV is equal to 0x3D800 that indicate FUS v0.5.3 is running on your board. So, you must update the FUS using the stm32wb5x_FUS_fw_for_fus_0_5_3.bin binary.

oups I did not see the small window below :) for the SBRV value.
