epcs boot problem!

Hi,

I have a problem about the EPCS boot.

I have already added the EPCS Serial Flash Controller Core and the Reset vector was the EPCS controller. Now , I can successfully download the elf and sof to the EPCS16 . When powered up ,the sof is loaded finely,but the elf doesn't work!

Can anybody encounter this issue ,please help me!

Best regards!
