Olimex AVR-JTAG-USB not reading fuse bits

Hi all,

I am using the Olimex AVR-JTAG-USB with AVR Studio 4.13 and an ATMega32. Everything works except reading and setting fuse bits, I can program, read the program, device signature, read lock bits etc.

I have pins 4 and 7 connected to VCC, 10 and two GND, 6 to reset, and 1, 3, 5, and 9 to the matching functions on the MCU.

When I go to the Fuses tab I get the following error message:

“A problem occurred when executing the command. See the command output for more info.”

and two more paragraphs with info on reading the trouble shoot section in the help file and a quick tip to ensure the header is the correct way around.

The dump window is showing

Setting device parameters for jtag programming …OK

Entering programming mode… OK

Reading fuse bits (low to high)… FAILED!

Leaving programming mode… OK

Any advice?

hi there,

i had the same problem.

it looks like its a bug in avr studio SP2.

found this:

i have installed new avr command line tools, uninstall avr studio completly and install new avr studio beta 4.14 from: http://www.atmel.no/beta_ware/ and its working fine.

Thanks vac, will give it a go tonight, but from teh AVRFreaks thread seems like this is the solution I was looking for.

UPDATE

That fixed the problem!
