the current platform SDK (version 1.1.0) provides some examples which are using interrupts.
The examples which are not using interrupts can be successfully loaded and started with u-boot commands.
If you try to to start an example (under u-boot control) which uses interrupts the system will hang.
Attached you will find a patch series which solves this issue on my side. (the patch is for RFC and contains only one example: epit)
BTW, for tests I use a Sabre Lite development board (i.MX6 quad core).
