More Robust I2C Designs with a New Fault-Injection Driver

Explore a 35-minute conference talk on improving I2C bus driver robustness through a new fault-injection driver. Learn about the challenges of writing error path code for I2C bus drivers and discover an affordable alternative to expensive I2C bus testers. Examine a GPIO-based driver that operates alongside the bus master driver under inspection, complete with a live demonstration and tips for handling discovered bugs. Discuss the scope and limitations of this driver, and gain insights into bus snooping techniques using only Free Software and OpenHardware. Benefit from Wolfram Sang's extensive experience as a Linux Kernel developer and I2C subsystem maintainer, while also learning about his background in embedded systems and vintage computing.
