hi all i need to upgrade a JTAG MK1 board i have tried the AVR studio but to no luck, avr studio does not pick it up and the the AVRprog is also not helping. i need the HEX file so i can upload it via the STK 500 i guess. any help?

the unit don't respond to the bootloading
Is it as REAL Atmel unit or a clone?If it is a clone then it all depends on how closely they copied the original tool.

Also some clones have USB adaptors instead of RS232, which makes life even harder as windows may assign to the adaptor a port number which is outside the usual com port range.

AVRProg only supports the AVR910 type programmers (which is similar to the ones found in older tools like JTAG Mk1) it will not work with the STK500. The "hex" file is in the JTAG folder but it is called ebn IIRC. Don't know if a normal programmer can use it.

edit by the way the Mk1 does not work with newer chips but only older ones.

Hi Js, it definitely is a JTAG MK1 original the branding on the box and PCB says atmel it has the atmel atmega163. there is no USB connection.

is there no way of converting this EDN file to a hex file for use with the STK500 to program the JTAG over again.?

There is no need for that, AVRProg does it for you. And you don't need another programmer, it has a 2313 (or 1200), AVR910 style programmer built in.

Are you saying that your computer HAS a real RS232 port then?

Power up you JTAG, then start AVRProg, if it does not complain about "no supported board found", select the Upgrade.ebn file from (usually) C:\Program Files\Atmel\AVR Tools\JTAGICE and try the upgrade.

Which com port is the JTAG plugged into? Have you selected the correct port?
AVRProg only supports ports 1-4.

It could be that the bootloader chip (a 90S1200 or a tiny2313) is dead. Have you measured if the chips have power to them?

oops AVRProg scans all ports so there is no set up for the port number.

hi Js,

if the JTAG is supposed to have any one of the above mentioned bootloader chips i think we found the problem. there is no such chip on the board. the only atmel chip is the ATMEGA163 which i gather is just the control IC for the debug part. do you think if i replace the bootloader ic with a new one the unit wil be able to load itself or do you think i need to lad it with a bootloader first?

I see. But I'm confused as I was under the impression that it would have a booloader chip too.

I'm attaching the manual upgrade info file but this assumes that the chip is not damaged.

If the chip is damaged then you will need to replace the chip and "procure" a bootloader which you should be able to program into the chip with the STK500.

The ICE should then respond to AVRProg. There are some bootloaders around the net for the ICE.

I simply use my AVR910 programmer to program the ebn file into the chip of my homemade old ICE. Where abouts are you located? Someone may have an AVR910 programmer that you could use.
