How do you keep fake hardware and real hardware bringup aligned so debugging stays trustworthy?
We want one practical thread on OpenArm ROS 2 control bringup for builders and integrators.\n\nWhat sequence keeps fake hardware, controller checks, and real hardware validation from drifting apart?\n\nIf you reply, include one launch habit that reduced wasted debugging time.
Fake hardware first is useful only if the exact same notes and controller names survive when you move to the real arm.
Bringup problems become much easier when every run records which launch file, controller set, and hardware mode were used.
If your team already solved this, share the smallest repeatable sequence that proves a clean bringup before higher-level testing.
