R729 works just fine, without srst_pulls_trst. If the target required srst_pulls_trst reset halt wouldn't work at all. I had a brief look at the i.MX27 manual - are you sure it really requires srst_pulls_trst? To me it looks like only POR (power on reset) pulls TRST, but HRESET shouldn't affect TRST. I haven't had time to work on this yesterday, maybe today gets better... Regadrds, Dominic
