Yes, irqbench requires a 16650-compatible serial or parallel interface
accessible via ioports, which is usually not available on embedded
systems. In contrast, gpioirqbench uses GPIO pins but getting it working
on the Beagle board is also not straight-forward. At least it does not
work out-of-the-box.
