11 Outline The Take-Home Kit Programming Debugging wsn.eecs.berkeley.edu

12 Programming What does it really mean to “program GINA”? – Programming the processor (MSP430) through JTAG interface – Write drivers to control the peripherals wsn.eecs.berkeley.edu

13 Programming What is JTAG – Joint Test Action Group (JTAG): common name for standardized IEEE “Standard Test Access Port and Boundary-Scan Architecture” – Initially: captured data is serially shifted out and externally compared to the expected results (debugging sub-blocks on Integrated Circuits) – Later: programming non-volatile memory How the Processor interacts with the peripherals – GPIO pins, I2C, SPI, ADC, UART wsn.eecs.berkeley.edu

14 Programming Using IAR… (demo) wsn.eecs.berkeley.edu

16 Debugging Debugging Techniques: – Blinking Leds – Single-stepping and Breakpoints – Using an oscilloscope – Using Sniffers – Using UART/USB interface wsn.eecs.berkeley.edu

17 Debugging Sniffers – TI’s CC2531-EMK pre-programmed with firmware which integrates with the TI Packet Sniffer Integrates with the SmartRFstudio Dissectors for IEEE , ZigBee, RF4CE and SimpliciTI – Atmel’s RAVEN USB stick Firmware by Colin O’Flynn ( Integrates with Wireshark Tools used by IPSO for IPv6 ready logo certification wsn.eecs.berkeley.edu

18 Debugging UART/USB interface – Using the Silicon Labs chip – Writing scripts to read incoming bytes (Python) wsn.eecs.berkeley.edu
