Hi -

 

As some of you know, I've inherited an unusual development environment in which IAR is used for development/build and Atmel Studio for debugging. I'd like to use one or the other entirely, for lots of reasons that I won't go into here. In trying to debug with IAR, I'm getting an error: Failed to initialize USB driver: error 0x20000007 ("Internal System Error").

 

I know that USB drivers have been a sore subject for AVR developers in the past. Is there currently a favored source for a driver that will work with IAR?

 

Specifics:

 

Windows 10 (yeah, I know)

IAR EWAVR 6.12.1
Atmel/AVR JTAGICE MkII

 

I could probably obtain a different ICE device if that's recommended.

 

Thanks for any help.

Yes ... WinUSB

Important information

The USB driver from Jungo has been replaced - customers who previously used the USB drivers from Jungo need to update to the new Windows USB driver, supplied in this installation $TOOLKIT_DIR$\drivers\Atmel.

Windows 10 USB underwent a major re-do from Windows 8.1; a guess is there's a subtle change.

Might try a Jungo from Atmel Gallery.

Well, that did in fact make a difference. I now get: Failed to initialize USB driver: error 0x20000009 ("No valid license")

 

If they're referring to the IAR license, they're mistaken...I'm licensed and have the dongle installed.

That Jungo is likely licensed to Atmel.

May browse IAR for a Jungo.

For IAR Embedded Workbench for AVR version 6.11 and later, follow the instructions in the JTAGICE mkII Driver Release Notes (the driver installation package is for example named AVRJungoUSB.exe, AtmelUSB.exe or AtmelUSBInstaller.exe - located in avr\drivers\Atmel).

Hi gchapman - yeah, I'd found that page. Has lots of good information; just nothing on actually obtaining said drivers. I also looked in my local installation of IAR, and I do have a file named AVRJungoUSB.exe, but its revision date is from 2011, so I don't think it's the version I want. (I did try installing it just for fun and I get the licensing error.)

 

Thanks for the suggestion, though...I'll keep snooping around.
