Download zImage fatal error

[Altera_Forum]

Hello all, 

I have question.  I connect two designs - nios2 and some part of fpga design for IF(radiofrequency) processing and after compilation, where i try to download the zImage, it finished with this report: ---------------------------------- Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Resetting and pausing target processor: OK Initializing CPU cache (if present) OK Downloaded 1915KB in 3.1s (617.9KB/s) Verified Ok Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Resetting and pausing target processor: OK Initializing CPU cache (if present) OK Downloaded 1195KB in 14.4s (82.9KB/s) Starting processor at address 0x02500000 assertion "m-state == STATE_DEBUG" failed "nios2debug.cpp", line 538  3 [sig] nios2-gdb-server 2220 c:\altera\90\nios2eds\bin\nios2-gdb-server.exe: *** fatal error - called with threadlist_ix -1 \cygdrive\altera\90\nios2eds\bin\nios2-download: line 594: 2220 Hangup  nios2-gdb-server --go --tccport none --write-pid ./nios2-download.pid ./zImage.srec --------------------------------------   Where is error ? From the first time, when i connect these designs, compilation finished with timing warning, but now it reports: -----------------------------------------------------------------------+ ; Ignored Timing Assignments ; +---------------------------------------------------------------+ ; Option ; Setting ; From ; To ; Entity Name ; Help ; --------------------------------------------------------------+ ; Cut Timing Path ; On ; * ; data_in_d1 ; std_2s180_reset_clk_domain_synch_module ; No timing path applicable to specified source and destination ; --------------------------   Is it jtag error or timing constraints ?    Thank you for answer.   Jan Naceradsky, Czech Republic
