I use the AVR ISP Software to program the device. It says "completed with no error" but when I do a "Read Device" the memory locations are all "FF". Further more, during the programing operation (as well as the "Read Device"), besides the programing LED, one of the PortB LED's (PB.3) was on as well. We have quite a few STK300 boards here. I tried two. They all act the same way. We got the STK300 Starter Kits from the seminar on March 9, 2001.

Did you try a different PC? Sounds like a problem with your PC installation since I can't imagine, ALL STK300s are defective at the same time...

Hi,

Are you sure you have the programmer configured for the correct device ?

for that one it should be mega103

Chantel,

The STK300 comes with a ATMega103L part that should be able to be programmed at the lower voltage setting of 3.3v. Co-workers have told me that the micro will handle programming at 5.0v just fine. I'm not saying that yours won't program at the 3.3v setting but it probably won't hurt trying 5.0v for programming. To change the voltage, move the jumper from JP1 to JP2. The minimum voltage spec for programming that micro is 3.2v

I've heard of a Beta version of ISP ver 2.7. I'm not sure what programming issues have been addressed with that software but it may help your situation if you can get a copy of it.

Thanks, Scott Pierskalla

Chantel,

I was told to check out http://www.lancos.com/prog.html. They have a programmer that is AVR compatible. I was told that it works better than the Atmel ISP in some ways.

I got my STK300 on Feburary 22 in at Atlanta. It too came with a ATmega103L. I'm using Atmel AVR ISP Version 2.65. First you have to start a new Project, then tell it what IC you are using

From there you can pull-down the Program menu and do Device Empty Check, Read Device, Erase, although I wouldn't erase it until I had something to replace the program with.

Incidently, when the IC is powered up the LED's should racetrack in sequence.

Thanks for ALL of your help. I'm still trying. I've tried on 1 NT station, 1 '95 station, and 1 '98 station but still no luck. The p.B3 LED is always on during programming operation. I did try 5v programming, and I choose 103/L for device. I tried with 3 different boards.

I think I'll try one more time on the '95 station 5v programming and then I'll try the http://www.lancos.com/prog.html site.

Does it work on Windows 98? NT??

Thank all of you,
Chantel

This sounds like a power supply problem. Maybe the input voltage to the STK 300 is not high enough to get the Mega part out of reset. The STK 300 I have also had a problem until I get the DC input to the board higher than the first supply I used.

Chantel,
I can program with a WinNT 4.0 station. Other co-workers say they can program with some machines on NT and others don't work. I haven't investigated the specifics since I can program with my machine.

Hi all,

If you do have problems with the supply voltage to the ATmega103L, do the following:

Replace the resistor R7 of 820R with a 1kR resistor.
The resistor R7 is located as the first one in the row of resistors beginning to the right of JP1 on the board, above the LEDs.

I wish I could post a figure too. Is this intelligible?

Best regards,

Hey!

Now I can attach a document! Nice going, AVR Freaks!

After changing to a 12v AC power supply I programmed the device using 5v programming on a Windows 95 and a '98 station. I guess it's the votage problem

Thank you all,
Chantel

on www.chat.ru free avreal - insystem programmer, simple - one 74hc244, I and my employees testing this programmer - very good and no problem.
