[En-Nut-Discussion] Problems Programming Ethernut Starter Kit 2.1

[Victor Behar]

Greetings to all,

I am using  Ethernut Starter Kit 2.1 with WinAVR and AVR Studio 4.11 SP3
and I have problems programming the board. A description of symptoms follows
...

-when i connect JTAG of  SP Duo to COM1 and run AVRStudio, the AVRStudio
"sees" it as
(Platform) STK500 or AVRISP and requests firmware downgrade from 31.32 to
2.01 ?
I would expect to be able to connect as JTAGICE mkII.

-however, fuses can be read or programmed without a problem (in this STK500
mode)
-hex files looks like they can be downloaded and verified when they are
"simple".hex (or the example led01.hex),
-others like httpd.hex get downloaded but AVRStudio returns "Problems
encountered..."
-but even with very simple code that sets bits of PORTD, I can't get it
work.

The other issue is when I compile httpd.c I get...
