Hello,
I have a USB AVRISP, just connected to codevision. The ISP looks happy, both greens lights on, when I hit program from inside CVAVR the green light flickers, so it looks like they are talking. I get the error :can not establish connection to device check, hardware, security bit, clock...
It all looks good. Tried all the SCK settings. What am I missing? I tried with both tiny13 and mega8.
Thanks,
Alan
Welcome back after 18 years.
Double check wiring?
Try another USB cable?
Use different software to test. Try this one.

With the following settings hit detect and see if it can detect your ATmega8.
Getting the same error? Or different?
Also make sure you don't have any components (LED, push button with pull-up resistor, capacitors to ground) connected to any of the programming pins.
These components may present too much of a load to your programmer.
ajmartin Thank you for the suggestion. I get a very similar error from avrdudess 2.14, so I know it is not a setting in CVAVR that is causing the issue. Tried several chips , so not a bad chip issue. Must be either my wiring or ISP. This was very useful.
Wow 18 years! seems like yesterday!

ajmartin Thanks, nothing connected to any pins , except wires for programmer.

Have a look at #1 in my signature below. Yes it's for a '328 but it'll give you an idea what you should be looking out for.

Please post a link to the actual device that you have bought. "AVRISP" might mean anything. e.g. Atmel genuine AVRISP-2 or some Chinese STK500 clone.
A photo of the pcb if you can't find the original purchase link.
If you have a Chinese USBASP you just connect all the wires and everything should work.
Likewise any other "known" programmer should work with Codevision.
The "usual" problem is that someone has altered the clock fuses.
Since you have a Tiny13 I guess that you only want to use 8MHz RC.
Supply an external clock to XTAL1 to recover fuses.

ajmartin It was indeed a wiring issue, really a transcription error. I had the pinouts of the ISP, the pinouts of the IC and the pinouts of the proto board with a 6 pin SIP that was wire wrapped to the IC programming pins and needed to be wired to the ISP dual in line connector. Somewhere along the lines I reversed pins 1 through 6 on one of the drawings, so every thing was backass ackward.
Thank you every one for the quick input.

david.prentice Is your programmer a genuine Atmel AVRISP-2 ?
Or a Chinese USB version that appears as a COM port and uses STK500 UART sequences ?
They should all "work". You just have to specify the "programmer type".
David.
