Advanced Topic 39 of 50 Mobile, Embedded & IoT

Hardware Debugging

JTAG, oscilloscopes and logic analyzers.

How it works

JTAG/SWD probes provide breakpoints and memory inspection; logic analyzers decode digital buses; oscilloscopes show analog waveforms; serial logs and GPIO toggling give quick visibility.

Where it is used

Finding firmware and wiring faults.

Common pitfall

Always verify power, ground and signal levels first.

Where it fits in the course

Hardware Debugging is topic 39 of 50 in Mobile, Embedded & IoT, rated Advanced. It follows Device Drivers for Embedded. The next topic is PCB Design Basics.
