Wireless Embedded Systems CSE190 Winter 2019 Lecture 6 Debugging Hardware Wireless Embedded Systems Aaron Schulman

Hardware is hard. Who do you trust when things are going wrong? Your software? Your users? Your test equipment? Your test equipment configuration? The device designer? The data sheet authors? The circuit board designer? The manufacturer and assembler? … Physics?

Data sheet errors are common Which one of these is correct? SAM21 data sheet in 2017, and 2018 for I2C

Manufacturing errors are common Circuit board manufacturing fault (signal shorted to GND) PCB assembly fault (“tombstoning”) resistors
