Hi,

Please verify my procedure. I added a Interval Timer in Qsys. Regenerated the system and burned the new compiled .sof file.

In NIOSII, i enabled hal.enable_gprof, assigned hal.sys_clk_timer & hal.timestamp_timer to timer in Qsys.

Included PERF_BEGIN(0x5020,1); & PERF_END(0x5020,1); before and after the part of code I want to examine.

Built the project and Run as NIOS II Hardware.

But I am not getting anything on my console window. It was built successfully but finally NIOSII console remain all blank.

I need to urgently come out of this.

Please help
