Problem with AVR-JTAG-L

I purchased a AVR-JTAG-L and have a problem with it. If I start AVRstudio and chose the JTAG programmer, the AVR-JTAG-L is found and respond. But every other thing I try result in a error. The only action I can see is that the led on the AVR-JTAG-L go on.

I now my hardware is good because I recently test the same hardware with the AVR-JTAG interface from atmel. This work good.

Is there someone who now a solution for this problem?

Tanks for the help,

how your JTAG is connected to your hardware, AVR-JTAG takes power from target, so your target must be able to provide it

what error you receive?

please send more info in order to help you

Hello Tsvetan,

When I start the JTAG programmer in AVRstudio I see this text:

Detecting… JTAG ICE found on COM2

Getting revisions… HW: 0xc2, SW Major: 0x7b, SW Minor: 0x00 … OK

Then I try to program the flash:

Reading FLASH input file… OK

Setting device parameters for jtag programming …OK

Entering programming mode… OK

Erasing device… OK

Programming FLASH … OK

Reading FLASH …

The “Reading FLASH…â€

all above seems normal exept the ReadFlash hang up

can you send us your target hardware schematic?

it is possible your target power supply vreg to be not able to provide sufficient current?

The problem is solved :smiley: . A friend forced AVRstudio to update the firmware. That was the solution for the problem. I think their was a small bug in the flash contents of the JTAG hardware.

Thank you for jour help.
