There is a test program installed with libusb: it should be called just "Test Program" in the start menu folder somewhere or in the libusb installation folder. (ex. C:\Program Files\LibUSB-Win32\bin\testlibusb-win.exe) You should see this device among all other: bus-0/\\.\libusb0-0005--0x1...

The function hvspEnterProgmode() definitely enables Vcc 40 microseconds before setting Reset to high voltage ... yes I saw it, and my genius idea felt apart, because I forgot, that I had triggered the SDO line, so the record starts when it goes high. I don't know why I don't see that on the reset l...

Well, I'm excluding more and more possible problems and every time I come at a dead-end. So far: - since I've used the two latest pre-build firmwares and haven't build it with gcc4, this shouldn't be an issue. - I've tried the programmer in AVRStudio 4 in CDC mode - everything - signature,lock bits,...

1. Have you installed linusb for windows? (http://libusb-win32.sourceforge.net/#downloads - the first filter driver)
2. If that does not help - post the error message.
Hope it works!

Here are 6 logic records after the execution of avrdude -c stk500hvsp -P avrdude -p t45 I post them as links because the images are too wide. http://lh5.google.com/duni.bg/RuVPVUziEbI/AAAAAAAAAJk/Bk3N4R_EbV4/prb1.PNG http://lh6.google.com/duni.bg/RuVPVkziEcI/AAAAAAAAAJs/NS1JItVRdIE/prb2.PNG http://l...

I'm still trying to fix my problem and I've done the following so far: - I've rearranged the I/Os of the atmega8 and rebuilded the firmware and hardware to ensure there are no broken IOs result: No success, everything works the same way. - I've analyzed the SCI, SII and SDO signals via tha parallel ...

My programmer also fails on tiny45. The uC has still it's default fuses and not programmed flash. I can't read the signature, it seems that the communication is there but something isn't quite right. When the uC is in the socket I get an error: Device signature = 0xffffff When I measure the signals ...

Note that if no device is connected the signature reads 0x000000, instead of giving rc-1 error as in ISP mode.

So I'm still searching and trying and I got so far: the atmega8 is ok, I can read it's flash and fuses with a parallel port programmer - this means that the pin 17- the data output is alright, otherwise I couldn't be able to read it. I measured and noted all the significant voltages on my board: htt...
