I bought this switch because I thought it had an esp8266 in it. When I found out that there was a BK7231 inside. I used https://github.com/openshwprojects/BK7231GUIFlashTool as instructed under Linux and Mono. I had to solder two resistors that were on TXD and RXD. I started programming, but after about 30% the program reported an error at the address s ended. Has anyone tried it under Linux? I am using Debian Boorworm.
