Honored ContributorHello,
I uninstalled Quartus 5, I erased the directories, then install Quartus 61. Since then when pluging my 1c12 board I got an error with jtagconfig.exe. it writes: 1) Nios II Evaluation Board [USB-0] 020830DD EP1C12 then I got an exception at 0x0044ba34 the address 0x00a78608 cannot be read. did I missed something during uninstallation installation? tahnks for helping Marc
Honored ContributorI have problems with the jtagserver too. It sometimes blocks access to both Quartus and the jtag uart.
Does flash programming from Nios IDE work OK for you? I get an error, probably a java GUI related problem. IzIHonored ContributorI alway got the exception, never works

Honored ContributorHere the JTAG server suddenly dies and does not restart.
This happens ONLY when there is traffic on the JTAG. Quartus SignalTap and Prommer will not find the JTAG Server and Q61 needs to be shut down and restartet. This is also the same with the Nios Ide as the nios-terminal will die too but the nios-terminal task is still present and needs 1 cpu core 100% until killed. But, the command line based prommer works ... currently no chance to trigger for a sudden event that happens now and then, cause jtag server will die shortly before the event occours :-( arrrghhh ...

--- Quote End --- I also had problems with the flash programmer in NIOS 6.1 IDE and I reported it to Altera. There's a bug in flash programmer, which will be fixed into NIOS 7.0. The workaround for me was to add a "short" name into the board name in SOPC. I.e. the board name should be like "Full name (Short)". I had only "Full name" and Flash Progammer gave an error when trying to create a new lauch configuration. Jari
Honored ContributorThis is the least comprehensive workaround I ever heard of, but it works (tested).
In the case that somebody does not get it, let me repeat how to do it: - open SOPC for your project - open the board description - edit the name of the board description and add the word "(Short)" to it - rebuild, recompile - test the flash programmer I hope somebody finds some better workaround soon.Honored ContributorI have a similar problem where jtagconfig gives an exception, but will continue.
Then when downloading the image nios2-dbg-server will lockup after the download, even from command line. terminating the process allows me to continue and i can eventually debug the code on the cyclone ii dev board. with the same software / hardware on my desktop machine everything works fine. I've tried disabling all software / firewalls /virus scan etc on the laptop with no success.
