Let's Control It

I try to compile latest espeasy mega-20191208 for normal_ESP8266_1M
Compile shows successfully without any error
However after flash binary file, no boot at all on serial terminal
No problem if using precompile binary from
https://github.com/letscontrolit/ESPEas ... 191208.zip
Obviously something wrong in compilation
Do I need to change something before compilation?
Below are all library and platform version, all up to date

How do you compile the binary?
What PlatformIO environment did you build?
