Most of the commercial integrated development environments had already sensed the potential behind the cheap and wide spread OpenOCD debuggers and had implemented ways of the interacting with such debuggers in their products Some of the popular commercial IDEs that work fine with ARM USB TINY are IAR EW for ARM and Rowley Crossworks for ARM The debugger also works with the free CooCox IDE Please note that the instructions below might not be accurate by the time of reading OpenOCD is a community driven open source project and things might change drastically between release version It is always advisable to refer to the official documentation of OpenOCD for latest instructions There are a such instructions on the OpenOCD web site Page 12 of 30 OLIMEXO 2015 ARM USB TINY user s manual 3 3 1 Getting OpenOCD You can either download a ready package or compile OpenOCD from sources The first choice is faster but the second option allows you to customize the OpenOCD and use a specific configuration One of the most important parts of such a compilation is the point where you select what drivers would be expected from OpenOCD FTDI or LibUSB If you are a beginner it is recommended to get an already compiled OpenOCD package If you are using Windows I recommend you to download an already compiled package for OpenOCD You can get it from here https www olimex com Products ARM JTAG resources OpenOCD OLIMEX WINDOWS zip Frequently upda
