1) I'm reversing a firmware image, Nucleus signature is there, but unfortunately the compiler signature is not.
The idea was compiling Nucleus and create an IDA signature for automatic analysis of my image.
So far I do not have the right Nucleus Plus version and the used compiler.
I just did a tedious manual analysis comparing the image code and the source of the v1.14 Nucleus I just posted here.
Not ideal but I was able to advance mapping important functions even when it's slow and error prone.

There are some Chinese websites (that I do not have access to) offering Nucleus Plus source code but
they do not mention their versions then is pretty darn hard finding the v1.11.1 I need.

2) I also evaluated the possibility of running the FW image under QEMU but no much progress,
the used processor is the CL PS7111 AFAIK not properly supported by QEMU and the hardware
evaluation board is not available today.

Thanks!
