[En-Nut-Discussion] Problems with JTAG SP Duo

[James Mclellan]

Hi folks,

This is a repost since the first did not seem to take.

I'm having trouble with "make burn" when using WinAVR.

$ make burn
uisp -dprog=stk500 -dserial=/dev/ttyS0 -dspeed=115200 -dpart=atmega128
--erase --upload if=httpserv.hex
Programmer is not responding.
make: *** [burn] Error 2

I'm using egnite's Ethernut Starter Kit with a 2.1B board.

I've checked the JTAG SP Duo LED, it is solid green, indicating it's
powered. I can also connect to the programmer using COM1, and have
determined I'm using firmware version 2.1.

I downloaded the AVR Studio, and am able to read my configuration bits
through the JTAG programmer. My fuses all appear to be right. JTAGEN,
EESAVE, CKOPT, BODLEVEL, and BODEN are all set 0. CKSEL=1111 SUT=11.
BOOTSZ=01.

Any suggestions? Thank you.
