Honored ContributorWhen I try to debug the simple_socket_server app in Nios II SBT for Eclipse I get the following error:
.gdbinit: No such file or directory. Reading symbols from C:/NEEK_Qsys/Ethernet3/neek_ethernet_fred2_good50_Copy/software/NEEK_example_sss_flash/NEEK_example_sss_flash.elf...done. Stopped due to shared library event Can someone please explain what I am doing wrong?
Honored ContributorHmm, so without the debugger your code does not reset? That is interesting... I'll try different debug levels and also removing the debugger on monday! :)
Thanks!Honored ContributorHonored Contributorkarlxmar: I managed to get my code running by making sure that no segmentation faults were happening... easier said than done, as the chip would just reset without indicating where the fault actually occurred, thus I had to breakpoint/printf my way to the error source.
I don't know much about the debugger and I am sure there must be a way you are supposed to do it (perhaps something to do with the exception stack?), in which case I haven't found it yet!Honored ContributorIIRC you can enable a 'misaligned address trap' and also an 'invalid address trap' (these may be on the 'hidden' options menu though).
These should cause an exception (interrupt) be triggered if you access an illegal (enough) address. Writing an exception handler to save the info and report it to the host is a SMOP. Probably easier if you don't have any 'normal' interrupts.Honored ContributorI've seen this problem before using Qsys / Quartus 12.1 - the signal to the JTAG UART reset line should come only from the NIOS JTAG reset line. All other resets should be removed from that line.
Honored ContributorFor the solution of this problem I removed project directories /db and /incremental_db. Close and restart Quartus II.
Honored ContributorFor me the problem came up when i copied the project and changed the frequency of my CPU. The solution was to clean and rebuilt the QuartusII project!
