Hi Haojian, The good news is this series works on the FVP models. The bad news is it hangs on boot for Versatile Express TC2.
I realise you won't have a TC2, so I'll have a look to see if I can work out why it's hanging. Unfortunately I'm getting ready for the 16.03 release at the moment, so I probably won't be able to look at it until late next week at the earliest, assuming the release goes OK. Cheers, Ryan.
