Hello, I am trying to flash an RTL8710BX with OBK using BK7231GUIFlashTool. But when writing the FLOADER, it hangs (always here:) I have tried several baud rates - always the same. What can I do?

On my first time, flasher crashed. But, since i didn't reconnect RTL8710BX board and floader was already uploaded everything else worked fine. On the second try there were no problems. Baud rate - 1500000. On my third try it hanged, but restarting flasher without reconnecting the device helped.

Thanks, good tip. It worked now on the 2nd try.I also used another Silicon Labs CP210x USB to UART Bridge.

worked on the 2nd try after flasher crashed.
