High-speed BDM/JTAG product uses GNU tools for debugging ARM processors

BDI2000 Penguin

Now available from Computer Solutions is the latest model in the Abatron BDI2000 range of high-speed BDM/JTAG debuggers based on GNU software tools.

The new model is specifically designed for debugging embedded systems based on the ARM7/9TDMI high-performance 32-bit RISC processor family.

By using an Ethernet link, the BDI2000 can communicate with the target at up to 2 Mbyte/s, and it is possible to load code for debugging at up to 320 kbyte/s. These high speeds streamline the debugging process for the latest generation of high-performance processors, which often have megabyte memories. Variable clock speeds are supported, along with target voltages of 1.8-5 V.

In addition to the normal GDB functions, the BDI2000 hardware can be used for stand-alone flash programming of internal flash memory or EEPROM at rates of up to 170 kbyte/s.

BDM (Background Debug Mode) and JTAG (Joint Test Access Group) are standard on-chip serial interfaces that allow developers to access embedded processors for debugging purposes. They offer a significantly cheaper solution than in-circuit emulation, and their use of low-pin-count connectors rather than chip interface connectors makes it possible to put a link on every port for flash programming and debugging in the field.

BDM requires no target resources in order to provide complete processor control, including starting, stopping, single-step, run to breakpoint, memory and register read/write and code download.

GNU software, available free over the Internet, provides a low-cost method of compiling programs for 32-bit processors, where the manufacturers’ tools are often prohibitively expensive for users like universities.

Other models in the BDI2000 range of GNU tools are available for the CPU32/32+, MPC5xx/8xx, PPC6xx/7xx/82xx, MPC7450, PPC4xx, TriCore and ColdFire processors. A version is also available to work with ARM’s own ADS development system.
