Avrfuses For Mac
I'm a new Mac user, coming over from Windows and Atmel Studio 6. Rather than setup a VM and develop under a virtualized winstance, I'd like to work with the AVR toolchain natively. After some searching, I found the CrossPack which promised I'd be up and running quickly. Unfortunately, I'm using a JTAGICE3, and the avrdude included in the pack doesn't see my programmer. From what I can tell, avrdude needs to be compiled to include support for libusb. Since several libusb. files are included in the CrossPack distro, I assumed this was done for me.
What's interesting about the design of this house is you can add a variety of design doors or windows with different basic materials, ranging from wood or glass. Containers are widely used in ports for storing imported and exported goods or often referred to as containers and box crates. Container home software for mac.
Is there a way I can tell if avrdude was compiled for libusb support? Does anyone have any experience working with the CrossPack setup? Or is there a better way to go about setting up a native AVR toolchain on a Mac? Bin $ otool -L avrdude avrdude: /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit (compatibility version 1.0.0, current version 275.0.0) /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 744.18.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0) /usr/lib/libedit.dylib (compatibility version 2.0.0, current version 3.0.0) /usr/lib/libncurses.5.4.dylib (compatibility version 5.4.0, current version 5.4.0) Guess I'll go with the build option. It's probably best to build my toolchain up from scratch anyway - will learn more that way and be better prepared to support it later.
Thanks again! Just omit -P port; it defaults to -P usb. However, you need AVRDUDE 6.1 to work with the CMSIS-DAP firmware of the JTAGICE3, and there's also a problem that the HID driver cannot be deallocated. Any pointers to that are welcome. I'll probably move to the HIDAPI library in a future version (in the assumption this one can work on top of the already allocated HID driver).
Another option were to downgrade the firmware to a version 2.x one which uses the old Atmel proprietary protocol (which has already been supported in AVRDUDE 6.0.1).

Avrfuses For Mac Os
But based on the last couple posts, we revisited this and got one of our JTAGICE3 programmers working on a Mac. Just used the avrdude that was included in CrossPack, (avrdude v. 6.0.1) and downgraded the programmer FW to 2.x. Of course, now it doesn't work with Atmel Studio.

Question: Has any work been done to get around the Mac HID release problem mentioned above? It would be great to have the ability to use our programmers on both platforms and have them running Atmel's latest FW. Plus, I'm not sure there is a downgrade option for the new Atmel-ICE programmers.
