I tired version 5 and 4.19 unsuccessfully. I checked my board and is working correctly with the same bit fuses used by the boot code. The rs232 communication is working correctly. I checked the communication using test programs. So no doubt that the M16 and the board is ok. Avr Studio 5 is way different from the previous ones. There is no menu to select which tool you want to upgrade nor how to select the communication port. The only option is upgrade firmware but who knows with port is using. I tired version 4.19 and it didn't work either. I used both version of boot loader and nothing. Which AVR studio version are you using? Thanks Hello

Which AVR studio version are you using?

Where is PC6? It doesn't appear in this schematic! http://www.scienceprog.com/wp-content/uploads/2006/11/jtag.pdf Do you have another schematic? Hello Javid
It didn’t work with me too.

Is this circuit work only with specific Avrstudio version , If so , What is it? Did anyone use this with AVRSTUDIO version 5 ? You used PC6 to select the mode , but it is not clear which position the jumper should be in each mode . it should be high for update or low? Regards, Hello Dear ScienceProg

Can you tell me how to set fuses. I cant use ponyprog. I think in ponyprog the fuses are inverted. In other programs are a lot more fuse settings like in ponyprog. Hallo.

And be sure to set fuses properly. Any programmer that works will do the job. And be sure to set fuses properly.
