Hi,

I am working on bringing up a new i.MX28 board we designed and the last output I get during the boot process is "start change cpu freq". As far as I can tell by looking at the boot_prep code is that the cpu frequency is being changed after this message is printed. I do not get any other output after this message and the board seems to freeze. Any ideas on what could be the problem? I am using the standard bootlet code from version 10.12.01 without any changes.
