I am using STK200. To program I use PonyProg2000 or AtmelAVR ISP.

Everything works fine for the AT90S8515-8-PC chip.

But it doesn't work for AT90S8535-8-PI chip. When I try to erase or program the FLASH in AT90S8535-8-PI I get the following message in PonyProg: "Device missing or unknown device (-24).

And in AtmelAVR ISP I get the following message: "AT90S7LS8535 Part Not Detected - this may be due to power off on programming module. Security Bits Enabled or pre production AVR."

I don't get these messages when I use AT90S8515-8-PC.

I know that STK200 supports AT90s8535 chip. PonyProg2000 and AtmelAVR ISP support it too.

Any Idea?

Atmel probably changed the device code. They did this for the 1200: I had to modify the SP12 programming software I use and recompile it.

Did you put the device in the right place. There is a separate foot for the AT90S8535. And yes, sometimes the device codes are wrong. You may try to switch this test off.

My own ISP-software has a separate test for a valid ISP-connection maybe your software is able to do that also. This way you can check for a living AVR without checking the device codes

if the device is plugged into the correct socket, should be in the A/D parts socket not the digital one. There is a checkbox somewhere in 2,65 that allows you to stop it reading the sig byte, its been a long time since I've used that version so I can't remember were. Some 8535 were changed I believe. I think they are obsolete now though, see the mega8535 which is their replacement.

Hello.

The STK200 had a board change or something, you should check the Kanada systems page, they detail where you have to cut some link and solder, depending on the rev.

IMO the STK200 is a pretty cheap and not too functional of board. I recall the A/D not working on a 4433 I was using because ARef wasn't actually wired correctly. I also found the hardware SPI port on the 4433 (when in this board) didn't work; the SPI clock line had some strange triangular variation, it wasn't a clean square-wave.

When I built my own board and used the *same* 4433 with the same software, the hardware SPI port worked perfectly, the clock trace was nice and square. For those wondering, my jumper settings were correct too.

The STK200 board is also covered with this ugly yellow mask which obscures your view of the traces. The result is that you don't have the ability to follow a trace to see if there is wiring problem.

It may not be an option for you at this time, but I would consider another evaluation board. Oh, and I think the STK500 does the same "we covered the board in ink so you can't see the traces" bit, the difference being it's white this time.
