Yes, but the intention here was to do it with bare assembly language. Normally one would probably do this from C by simply calling open() and mmap().
That means, the Act LED of the RPi 3A+ is on GPIO 29 like on the 3B+ and the 3A+ is widely compatible with the 3B+. USB works in host mode like on the RPi 1A+ or RPi Zero. Thank you very much for testing!
