Need help programming STM32WB55CEU6 CPU2 BLE firmware.

Hi, 

I have in hand a customer board with a STM32WB55CEU6 MCU. I was able to program CPU1 (M4) firmware but it seem that CPU2 (M0+) didn't have any firmware programmed.

I have found that I need to program stm32wb5x_BLE_Stack_fw.bin into CPI2. Did you have a simple procedure to do that?

Board only have jtag interface SWCLK, SWDIO line, no uart or USB connector, BOOT0 line is available but NC for now.

Any help will be greatly appreciated.

Regards,
