Problems with AVRJTAG and atmega128

Development Boards MicroMod

Hi all,

I’m trying to use the AVRJTAG with the atmega128 and AVRStudio.

I’ve updated the AVRJTAG with the AVRStudio as described on the OLIMEX page. Now I load the *.cof file of my application and choose in AVRStudio the JTAG ICE platform and ATmega128 device.

The application is not running on the device and if I break the execution, AVRStudio will give me the following error messages:

Loaded partfile: D:\Programme\Atmel\AVR Tools\PartDescriptionFiles\ATmega128

Loaded objectfile: D:\Projekte\Atmel_AVR\Test_128\test_128.cof

Error reading memory IO Address:0 Size:64

Error reading memory REGISTERS Address:0 Size:32

Error reading memory SRAM Address:96 Size:160

JTAG ICE Warning: Reading the program counter, an invalid value (0x7FFFFFFF) was received from the device.

Error reading programcounter

Error reading memory IO Address:0 Size:64

Error reading memory REGISTERS Address:0 Size:32

Error reading memory SRAM Address:96 Size:160

I can read the signature and handle the fuses in the JTAG ICE dialog box.

Both fuses - OCDEN and JTAG - are correct (marked).

What I’m doing wrong. Do I need a bootloader already installed in the device?

Any suggestions?

I have checked my schematic. There was a permanent connection between the /PEN pin an ground (maybe a hair on the mask of the my board). So the atmel was permanent in programming mode and do not execute any code.

Thanks for food for thought :idea:
