[avr-gcc-list] Cannot use my new JTAG for programming

[Juergen Harms]

I completed my initial learning period programming an ATmega16 that sits 
in a STK500v2 - no problems. I now re-did things on a small breadbord 
(essentially the "simple project" layout of the avr-libc demo-projects), 
and tried to write the program (initially tested and developed on the 
STK500) now in-circuit programming with a newly purchased JTAG: and got 
stuck (and I have correctly written the OCDEN fuse bit to 0).

What works OK:
Calling "avrdude -p m16 -c jtagmkII -P /dev/ttyS0 -t"
and interactively dumping and writing flash, (h/l)fuse, eeprom

What does not work:
Writing program code to flash or eeprom, using avrdude -p m16 -c 
jtagmkII -P /dev/ttyS0 -U flash:w:timer.hex (or eeprom:w:timer_eeprom.hex)

The response from avrdude is appended to the end of this message 
(essentially some not necessarily fatal messages complaining about 
time-out and firmware version), and evidence the the write/readback of 
program code failed - paritcularly amazing the message that lfuse could 
not be read properly). Checking in terminal mode after the failed 
programming tentative, something has been written to the ATmega16 (I did 
my work with an entirely new processor, no possibility of a "tired" 
flash memory, and also tried another processor).

I then went back to my STK500v2 and piloted it (not, as before, directly 
through its RS232 port) but from the JTAG, plugged via the "STK500 JTAG 
ADAPTER" with the same result: OK in terminal mode, but total failure 
when trying to write code from a file to flash memory or eeprom.

If I call avrdude with the -v option, I get the following complementary 
information:

avrdude: Version 5.3.1, compiled on Feb 20 2007 at 22:01:48

         Programmer Type : JTAGMKII
         Description     : Atmel JTAG ICE mkII
         M_MCU hardware version: 0
         M_MCU firmware version: 1.06
         S_MCU hardware version: 0
         S_MCU firmware version: 1.06
         Serial number:          00:a0:00:00:06:33
         Vtarget         : 5.0 V
         JTAG clock      : 891.7 kHz (1.1 us)

What can I do to further clarify the situation - is it possible that I 
received a JTAG with an old firmware version (I bought it from a company 
with which I have only had positive experiences so far) that does not 
work with the recent version of avrdude ?

Thanks for any help, Juergen
