Debugging with JTAG - Alexander Rusev, Kernel Engineer, MontaVista Software
This session examines a mixed software-hardware approach to embedded systems debugging. JTAG electronics system principles will be reviewed, starting with hardware and finishing with advice on using JTAG with open source software tools for embedded project development. Several JTAG use cases will be considered, including chip interconnection testing, automatic chip testing, flash programming, and SW/HW debugging. The internal complexities of JTAG-related technologies will be discussed along with practical applications such as microprocessor software and firmware development, and JTAG use with PCB, FPGA and ASIC technologies. JTAG hardware equipment from different vendors will be reviewed in conjunction with software tools that simplify the use of the equipment. A live demo will be given of applications using JTAG-related plug-ins for IBM Eclipse with the Linux kernel, including bootloader firmware flash-in and debugging. (45 minutes)
