Debugging eCos

[Altera_Forum]

Hello Community, 

 I have some problems with eCos and debugging! I use the Altera Stratix Development Board. There are a JTAG Interface. Now I want to develop an application for eCos but I can´t debug any application with the JTAG interface. If I want to debug an internal eCos function there occurs an "no sources found" error! What I have to reconfig in my ConfigTool to debug applications and eCos functions with the JTAG interface? Or I have to debug with RedBoot? When I build a RedBoot Library I got an global pointer exception! I trying with the Linke -G0 Flag but it does´t work! Can anybody help me?

  Ans :- In the Nios2ConfigTool, eCos HAL -> Nios2 architecture ->Debug Device  Make it /dev/uart1  Similarly select the console device also based on your need.  Hope this is what u meant!  Thanks Akhil
