I do not use echo in my application. I write out the value properly. And 
when I use the echo to test, I have been using "" around the value. I 
found that difference out myself.

Yes, it would appear that I do not need to change the ldo4, but I do 
have to toggle the reset. This is not in the wiki page. So, is power_on 
going to change to do an implicit reset, or is the wiki page going to 
document the requirement to toggle reset?
