    Have you stepped through the DM355 DVEVM Getting Started Guide (SPRUF73)?

    The ./loadmodules.sh is a BASH shell script that is executed by the target.  You can cat this file and see what is attempting to do.  By default, the loadmodules.sh is assuming cmem.ko, mapdmaq and dm350mmap.ko are resident in the same target directory that you are executing ./loadmodules.sh.

    I seem to recall that during the process of building the DVSDK, one of the steps is a "make install" which copies these files into the target filesystem.
