Hello to all!

It's possibile to use the loopback technique to test SPI device on the STK500?
There are some related problems with the STK500, if i use this technique?
I have used this technique, and now my stk500 doesn't work, i have burned it?

 

Please someone help me, because if i have burned it i will try to find a remedy, because i'm not an expert and i have to finish a project and i not have much time a disposition.

Hi bobgardner, I think that the problem was the software.
I have read some post on the this argument and from these I have arrived at the file "fix stk500". I have done the steps described in this file, but not all steps because i haven't an oscilloscope, i have only a multimeter. I have checked the hardware: the vcc on the micro on the stk500, voltage around max202 and serial communication on the spare port. Everything worked.
So, thank the advices of jgmdesign, i tried to reprogramming the firmware of the stk500. After some attempts I was able to establish a connection with the board (using the usual procedure to upgrade the firmware) and with the help of avrprog i  updated the firmware on my board. Now it works. smiley
