Hello FORUM !!!
About a 5 days (and nights) I am discovering a serious problem to connect
AVR-MT-128 board to AVR studio 4 with AVR JTAG USB unit.
Every trial to connect, I get note screen from AVR studio ...
"The OCD JTAG adapter was detected, but the target device did not return a valid JTAG ID."
.....
.....
Trying all combinations to make it read the switches - nothing
I am using USB-RS232 port #2 to connect, Latest AVR studio (+ SP3 update)
I read all topics on all forums to find the solution(s) - including external PS connected to Vcc/Gnd pins.
I made all suggestions from OLIMEX ......
While now - Nothing.
The board runnning some demo program very well.
But, there is no way to program any another program
(The MOD-IO board with ATMega-16 works fine every time I switched back to it)
Can anybody tell me, where is the truth ?
Can I program the board with any ISP programmer ? (may be to update the JTAG swithes)
I don't know what else, I can do.
Need help ASAP.
Thank you in advance for any help,
Radislav
