UART in DMA mode (using driver in ROM)

I try to configure UART in DMA mode by using driver coming with CCES. It works when I use the RAM version of the driver.


But it does not work when I try to use UART driver in ROM through UTILITY_ROM_UART option. 


But if I configure the UART in interrupt mode, the driver still works. The silicon version of processor is 1.0. 


I would like to know if anyone else has encountered same problem. Is there any solution for that?
