hi everybody, i’m having problems with my porting on verilog-emulated mips architecture. I’m totally newbie, so anybody can give me some advice on what should i put in *pxPortInitialiseStack code on port.c source file? thanks.

I would recommend looking at the PIC32 port, which uses a MIPS core.  FreeRTOSSourceportableMPLABPIC32MX.
