Hi Andy,
Please ignore my earlier e-mail. In an attempt to compile
the DYNAMIC_DEBUG, I forgot to compile the dmatest under the
dma_drivers. Now with the test included, it still gives the same
error.

What I suspect is that it may not have a Shell instance. Could you
please help clarify what Shell is needed by the test to run? Do we
need to install a shell separately in the kernel image?
Thanks & Best Regards
