Providing developers with an optimised testing and debugging environment for Infineon’s XMC4700/XMC4800 MCUs, Version 4.4.5 of the Universal Debug Engine (UDE) has been released by PLS Programmierbare Logik & Systeme.

The 32-bit SoCs, which are based on an ARM Cortex-M4 processor with FPU, were specifically developed for use in industrial applications. The MCUs feature a comprehensive range of peripheral functions such as an EtherCAT communication unit (XMC4800 series) and six CAN nodes. PLS’ UDE 4.4.5 fully supports both the peripheral units and the internal debug resources of the new high-performance MCU family. The integrated FLASH/OTP programming functionality of the UDE guarantees maximum speeds in the whole Delete-Download-Programming-Verify cycle.

The various possibilities for graphically displaying variables and their links to physical values within the UDE benefit above all from the real-time properties of the XMC4700/XMC4800 family. For example, it is possible for the debugger to read and write the entire main memory whilst a program is running without impairing real-time behaviour. This permits the animation of variables, registers and memory content at runtime. In addition, the periodic recording of the instruction counter permits a profiling function with portrayal of the percentage share of functions in the application’s runtime. The integrated units for program, data and performance trace are also fully supported.

Furthermore, in combination with PLS’ Universal Access Device 2 (UAD2) family, developers can use the built-in bootstrap loader implemented in the Infineon XMC4700/XMC4800 SoCs to program the on-chip flash memory via an asynchronous serial interface or the CAN bus. A digitally isolated connection to the target is also optionally possible with the UAD family.

If required, a full Eclipse integration via an own debug perspective with complete cross-debugger functionality is also available.

PLS’ UDE 4.4.5 is available now. According to Infineon, samples of the XMC4700/XMC4800 devices will be available in August 2015.
