I have the Robotron working fine with XP. I'll try and assist if you need anything. Just let me know.

All seems to be okay now as I can successfully used avrdude serial & hid modes. Avrstudio is also now working via pc usb port. I really appreciate all your time and effort in this project as well as putting up with me.

Once again, thank you.

I have sent the email. Thanks.

The 8515 is powered via battery. I do not use usb power for it, just ground, reset, sck, mosi & miso. The usb hub/doper is powered via motherboard.

Works only in HID. Tried via other mode and rec'd: C:\WinAVR\bin>avrdud -c stk500v2 -p 8515 -P com4 -y -u -U flash:w:test.hex avrdud: AVR device initialized and ready to accept instructions Reading | ################################################## | 100% 0.23s avrdud: Device signature = 0x1e9301 ...

I am supplying 9V into a 5V reg (7805) on the breadboard for the 8515. Measured a couple of times just to verify. 4.99V according to my Fluke. Works well though with parallel cable thru Bascom. Any other thoughts?

My old scope doesn't measure this very well. I tried during the reading process but the scope just doesn't handle it too well. And it could be me not knowing how also. But if I'm reading this right, it looks to be a pulse width of 5 usec.

My old Heathkit scope is about to die but the SCK line does go high during the attempts. Now what?

Basically it does the same, in or out of HID mode. Reads but no write. SlowSCK is open now. If I close that jumper, it programmer fails in HID mode.

I can read the AVR just fine, but it will not write. I do have a scope here but what pin is the ISP clock?

Thanks.

The test circuit I am trying to program is a 8515 with a 10Mhz crystal. It programs fine with the simple parallel cable.

Any other ideas or things for me to try?

Thanks!

The previous post was non-HID. This is the HID text ---> C:\WinAVR\bin>avrdud -c stk500v2 -p 8515 -P avrdoper -v -u -U flash:w:test.hex avrdud: Version 5.3.1, compiled on Jan 10 2007 at 14:17:33 Copyright (c) 2000-2005 Brian Dean, m System wide configuration file is "C:\WinAVR\bin\avrdude.conf&...

I am really unsure as to the correct line parms for avrdoper but here it goes.
