I have now done some tests on i.MX31 PDK: * v2013.04 and v2014.04 works * v2014.07 and "tip of tree as of this mail" does not work To make it work (both v2014.07 and tip of tree) I only have to change the "ldr pc, _reset" to "b reset". I do not have to apply the nop-part of the patch. On a different note I noticed that I received a warning that the PDK board does not use "generic board", I will try to fix this but I don't know how much work that is and when I can submit a patch.
