Correct. It works fine in linux. I've even tried to port linux code that enables watchdog (booke_wdt.c/__booke_wdt_enable()) to u-boot, but was not successful. Watchdog never triggered, although I did not refresh it. I'd appreciate some advice on what may be different in u-boot vs. linux. Thanks a lot.
