The module routes the USB D+ (DP) and D- (DM) signals out to pads, providing the system designer with the ability to choose the type of USB connector and its location on the system board. Users can connect JTAG signals directly to the corresponding FPGA signals, as shown in Fig. Find great deals on eBay for usb jtag nt. Shop with confidence.
Usb Jtag Nt For Mac
[This post is derived from. I was told that I'd have better luck focusing this as a Mac-related question rather than a more general avrdude question.] So I have been successful programming a typical flashing LED program from my Mac to an ATmega168 on the STK500 (using the Keyspan USB-to-RS232 adapter). I want to get familiar with debugging, and I was under the impression that I could do so with the JTAGICE mkII. My plan is to start simple by programming the device with the JTAGICE mkII via ISP, and if that works, try debugging with debugWire. I've read through the JTAGICE mkII quick start guide and the, as well as the relevant, but am still coming up short.
Unfortunately, this documentation is primarily Windows and AVR Studio specific, so I wanted to find out if anyone on AVRfreaks has successfully used the combination of Mac OSX / STK500 / JTAGICE mkII and can help me out. First of all, the online documentation mentions that USB drivers need to be installed just after installing AVR Studio.
As far as I know, I've never had to install Mac USB drivers (whereas I did back in the day when I worked on a Windows box). Is this step necessary, and if so, how would I do it, since the drivers are for Windows? Next, for my hardware setup I have the JTAGICE mkII plugged directly into the USB port of the computer, and I'm fairly sure it's getting 500 mA. (I've also occasionally attached directly to a 12 V supply, which doesn't seem to be any different, as one would hope.) The JTAGICE mkII is attached to the green SPROG2 header on the STK500 via the combination of flexcable, target adapter card, and 10PIN-to-6PIN probe adapter cable. I do not have the RS232 cable connected to the JTAGICE mkII, but (a) I assume this connection is taken care of via USB and (b) I haven't seen this connection made in any of the documentation. (I think this is for Windows 95/NT machines without USB anyway.) The JTAGICE mkII lights are green (target power), red (JTAGICE mkII power) and red (idle, not connected to AVR Studio, which makes me somewhat concerned about whether this will work at all on a Mac or if the JTAGICE mkII is hard-wired for AVR Studio).
I have disconnected the RESET jumper on the STK500, and have left the STK500 connected to the computer through the Keyspan-RS232 combo. In my Makefile (created with Mfile with a few customizations), I have these lines of code. Clawson wrote: But avrdude is just a programmer software.

If you were going to use a $299 JTAGICEmkII ony for programming you might as well have bought a $34 AVRISPmkII. The main use of a JTAGICEmkII is debugging. For that you need to look at using avarice rather than avrdude.
You then use GDB (probably from Eclipse or DDD or Insight or something) to communicate with the chip via avarice. The question is now if the USB drivers installed on perchrc's machine support debugging in addition to programming. I'm looking into purchasing a clone () and am interested in the answer. Perchrc: I assume you're talking about libusb?
If so, avarice has to be configured with usb support. I'm assuming the MacPorts has the configured version.
You can verify this by opening terminal and typing otool -L /path/to/bin/avarice and looking for libusb in the output. Here is my output, void of libusb.
