JTAG USB OCD Tiny - Programmer/Debugger for ARM processors
This is a low cost USB-based JTAG programmer for ARM processors based on the OpenOCD platform.
- Debug all ARM microcontrollers supported by OpenOCD
- High speed USB 2.0 with lower lattency time, RTCK adaptive JTAG clock up to 30Mhz and higher throughput achieve x3-x5 times faster programming speed than ARM-USB-TINY, can be used with all ARM devices for programming and debugging.
- Uses ARM's standard 2x10 pin JTAG connector
- supports ARM targets working in voltage range 2.0 – 5.0 V DC
- software supported by OpenOCD (open source) debugger
- downloadable Windows installer for full featured and open source tools as alternative to the commercial ARM development packages: GCC C compiler, openOCD debugger and Eclipse IDE.
- works with IAR EW-ARM 5.50 or newer
- 50x40 mm (2x1.6") + 20 cm (8") JTAG cable
JTAG USB OCD Tiny - Programmer/Debugger for ARM processors Product Help and Resources
Core Skill: Programming
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

For what it brings to the table it rocks.
It's inexpensive as all get-out and it does work as well as the big-boys for a wide range of tasks (Just don't expect it to be a barn-burner for the same.)
Any chance that Sparkfun will stock the high speed version with adaptive clock?
http://olimex.com/dev/arm-usb-tiny-h.html
Olimex price both standard and 'H' version the same.
I was also looking for the arm-usb-tiny-h and surprised Sparkfun wasn't carrying it. I tried here first, but will be going elsewhere to get it.
At $60, the Segger J-Link Edu is a much better product (assuming you are not developing a commercial product.). Will Sparkfun carry this item?
I have a question- what are the differences between JTAG programmers? I've found a HUGE price differential between high and low. What's the deal?
I assume this is the high-speed version (ARM-USB-TINY-H), since that's the Olimex page that is linked to above.
Or is it the version with the built-in power-supply (ARM-USB-OCD) and serial port? That's the product brochure that comes up when you click on the link above.
This adapter could also be used to program PIC32 microcontrollers. Try pic32prog utility: http://code.google.com/p/pic32prog/wiki/README
Burned two days trying to get this to work in windows. Never did figure it out. Bought a JLink and was programming/debugging in 10 minutes.
Yeah, a J-Link is also $300, unless you qualify for a $60 J-Link EDU.
I can't find this anywhere, here or on Olimex's site: does this debugger support the SWD protocol on the newer STM32F10XXX Cortex-M3 processors?
is this one can be used for the Blue Screen development board?
Yes, it does -- it comes with a CD with software and with a 20-pin cable (about 8-inch long, looks like).
Does this come with the 2x10 cable?
All i see is:
Uses ARM's standard 2x10 pin JTAG connector
I got this programmer because I needed a USB version to replace my parallel port one. With the supplied CD I was programming/debugging a SAM7H64 board from Olimex in less than 30 minutes.
