Hardware initialize in the h.264 encoder application

Hi

The device: c6678

The CCS edition 5.2

My work is based on the demo project h264hpvenc_ti_c66x provided by the H.264 encoder(edition 01_00_02_00). It needs to run the EVM6678l.gel to initialize the hardware like pll,ddr etc first, but these work has to be done in the application.So I add the code in the .cfg file:

var Pcie = xdc.loadPackage('ti.drv.pcie');

Startup.lastFxns.$add('&HwInit');

where 'HwInit' is the pcie configuration function.

Then the application stucked at the multicore sync after shared memory initialize.

I want to know  if the hardware configuration should be done at the startup,if not, where it should be?

Thank you for any advice,

Cui
