[En-Nut-Discussion] Problem with Httpd Sample

[Tolga Onbay]

I changed the programmer from avr-uisp-stk500 to avr-dude. And the error was
disappeared. But there are problems.

In "make all" it gives warning as below :
httpserv.c:341: warning: assignment discards qualifiers from pointer target
type

Also "make burn" is not working properly. In output there is so many timeout
messages. I think there is a problem. I attached the outputs of "make all"
and "make burn".

I found the version of SP Duo as written in documentation. Its version is
2.1. Do i have to change something? And also i didn't install avrdude 5.0.
Do i have to install it?

Also I can't find "Generate Build Tree" in Build menu as written in Ethernut
Software Manual.

ethernut version : 4.0.3
WinAVR version : 20060421

Thanks
