See the Q&A section in http://www.denx.de/re/DPLG.html Either you're passing a wrong bd_info structure, or a wrong clock frequency (see also the PPCBoot README about the "clocks_in_mhz" stuff.) > I am using the vision ICE currently to debug the kernel start up but it has > a problem stepping through the 'rfi' etc when memory protection is running. You cannot step through rfi, not with any BDM debugger.
