ADuCM331 "Invalid ROM Table" Error

Hi,

I'm working on a design with ADuCM331. When I use ARM Ulink Plus SWD interface to download program to my prototype I get the error Invalid ROM Table.

I tried to use lower clock speed and changed the setting but no lucky. There are some solutions about the Invalid ROM Table issue but no one works for me. Does someone know what could be the reason? Thanks.
