Unable to upload Coprocessor binary

I have a problem while using BLE using STM32WB55CG in my custom board.

​

I tried steps ​explained on UM2550 - 5. How to flash the wireless coprocessor binary.

​

But the custom board doesn't have any USB port so I tried to upload with ST-LINK(SWD).

​

And I entered a command like this :

STM32_Programmer_CLI.exe -c port=SWD -fwupgrade C:\Users\Administrator\STM32Cube\Repository\STM32Cube_FW_WB_V1.3.0\Projects\STM32WB_Copro_Wireless_Binaries\stm32wb5x_FUS_fw.bin 0x080EC000 firstinstall=0

​

But it always throws an error like this :

Error: Could not execute fwupgrade command, Security extension not instantiated.

​

​The data at 0x20030030 are 0x00000000.

The binary file I'm tring to upload is "stm32wb5x_BLE_Stack_fw.bin".

How can I upload the coprocessor firmware using SWD port?

Thank you.

CubeProgrammer v2.1 does not support co-processor operations via SWD. Update to at least v2.2.

Use port=swd mode=ur to connect under reset to guarantee sustainable connection

Also FW_WB_1.4.0 is available

The programming through the SWD port requires to set some option bytes i a different way than via the USB port.

The exact command is ​

cli.exe -c port=swd mode=UR -ob nSWboot0=0 nboot1=1 nboot0=1 -fwupgrade %BLE_STACK% 0x080CB000
