description: Automate on-target verification of a program's logic by driving its RTT console with rttsh - write Lua scripts that exercise commands and assert responses, output and timing on real hardware. Use when asked to verify target-side behavior on board, build board-level checks for firmware features, or automate hardware test runs.

# rttsh verify on board

rttsh is the tool; the thing under test is the target program's logic.
Scripts drive the program's console over J-Link RTT: send commands, expect
replies, assert behavior, output and timing - everything a hardware test
needs, automatable end to end.
