Hello! I have the STM32WB55CEU6 chip on my custom board. I try to flash BLE Stack via ST-LINK_CLI (SWD interface), but the following error is returned: Could not update the option bytes!
Extended Log is attached.
Also I have USB dongle on STM32WB55 (board MB1293C). I've connected SWD to the board and it is successfully flashed (chip from this board has earlier flashed BLE stack). I've soldered chip from MB1293C to my board and it's also successfully flashed. Then I've soldered the chip from my board to MB1293C and the flashing is failed. How to flash BLE stack in my chip?
