That's not going to work because the Redboot code isn't relocatable like
that.  Like you can't just load it and launch it from any location.  If I
understood you right, you're trying to launch a ROM or ROMRAM image from
within Redboot.  This is probably not what you want.

You can configure a Redboot image to be launched from RAM, but this is
generally not necessary unless you're doing special things (eg. replacing a
Reboot ROM mode image, etc.)

Beyond that, without seeing what's going on in the HAL setup
(hal_platform_setup.h), it's difficult to guess which of any number of things
it may be tromping over that could cause it to hang.

I'm still missing what it is that you're ultimately trying to do here.
