Hi, I am using waveshare's https://robu.in/product/bluetooth-4-0-nrf51822-eval-kit/ and using STM32f407 discovery board (removing the jumpers for using SWD connector) for flashing using onboard STlink V2
But after trying to flash get the below error `Arduino: 1.8.19 (Windows 10), Board: "Waveshare BLE400, 32 kB RAM, 256 kB flash (xxac), S130"
