Hello.
I used Cyclone III web_server example to launch uClinux on my Cyclone III start kit. The reference sof & zImage works fine and I can see the uClinux logo. But when I compile zImage by myself with dts extrated from reference sopcinfo and download to the starter kit, I got below error. I am new to uClinux & niosII and could not find any clue for several days. Would you please help me? sopcinfo, dts and configuration files are attached.
