Re: Help on AutoGen Files

Hey Udit,

You cannot explicitly influence the order of the calls, but implicitly via the dependency tree, which means you need to make SerialPortLib depend on your LibraryClass instance.
You did not mention which SerialPortLib instance you use, but probably you need to execute FpgaInterfaceInit() earlier in platform code or fork SerialPortLib for now.

Regards,
Marvin
