HARDWARE:

• ARM JTAG connector (top view)

SOFTWARE:

• Olimex's ARM GCC for Windows Dummies install CD - installs on your computer WinARM + OpenOCD debugger + Eclipse for out of the box development with the open source GNU C compiler and OpenOCD debugger, supports flash loading on LPC and external flash for LPC-H2214, LPC-H2294, with make examples for different ARM controllers. The current revision of the CD is REV.G check the CD content.
• Drivers for working with OpenOCD , Drivers for CrossWorks (FTDI drivers)
• openOCD open source debugger from Dominic Rath for debugging with Insight/GDB.
• Using OpenOCD as Flash programming tool article written by Martin Thomas
• ARM projects with OpenOCD by Martin Thomas
• WinARM - easy to install open source GCC toolchain by Martin Thomas. We are working on CD install package for WinArm+OpenOCD+ARM-USB-OCD support
• CrossWorks - commercial IDE version 1.7 supports all Olimex JTAGs, personal licensees start from US $125(!)
• Building GCC for ARM tutorial
• Building GCC for Cortex tutorial
• Using OpenOCD tutorial
• For the moment the only supported package is GCC C compiler + openOCD debugger + Eclipse IDE. Olimex can provide the necessary information and cooperate with interested parties if they want to add low cost USB debugger support to their C compilers and IDEs.

Q: Can I use ARM-USB-TINY-H with EW-ARM?
A: IAR have beta support for GDB server in their 5.xx version of EW-ARM, and OpenOCD can be used as GDB server, but as their displaimer says it's limited to STR, so as a whole this combination is not reliable and well tested. So it may work or it may not work, hopefully the GDB support from EW-ARM will be improved in future.

Q: I use Windows XP x64, how I can update the USB drivers?
A: FTDI have x64 drivers on their web, download them and use our ARM-USB-TINY PID: 0x0004, VID: 0x15BA to install the drivers.

Q: how to install ARM-USB-TINY to work with CrossWorks:
A: Use: "Generic FTD2232" target interface
1. Right click on a blank space in the targets window and select "New Target Interface > Generic FT2232 Device".
2. Right click on the new target interface and select "Properties" - set the following properties:
nSRST Inversion Mask 0x0200
nSRST Mask = 0x0200
nTRST Inversion Mask = 0x0000
nTRST Mask - 0x0400
Output Pins = 0x0F1B
Output Value = 0x0408
PID: 0x0004
VID: 0x15BA
In CrossWorks 1.7 there are Target interfaces for Olimex JTAGs, note that RTCK is not used with FT2232 design so your JTAG clock should not exceed 1/6 of your target MCU clock or the JTAG will lock up, start with JTAG divider 10 and decrease until you are able to debug to find your own value for your target.
