BROM firmware source code #44

Hello! I'm using MQ-Pro which uses the D1 chip and it works great with xfel so thank you for a great project! I'm wondering if source code for the firmware that xfel communicates with is available somewhere. I'd like to understand better how it works. Of course I can dump the assembly starting at 0x0, but it doesn't have any symbol information, and it looks like it's using undocumented memory regions such as 0x70005e0. Thanks!
