What is wrong when running L138 LCDK EDMA3 LLD example

Hi,

I import EDMA3 LLD example from folder:

C:\ti\edma3_lld_02_11_11_13\examples\edma3_driver

When it is loaded and run,  there are such errors:

edma3init() Failed, error code: -128
edma3init() Failed, error code: -128

I suspect that some ram mapper errors, but I cannot figure out what is wrong. I have attached the project here.

I also find the edma_drv_bios6_omapl138_st_sample_configuration project has unsolved variable:

Could you tell me how to run EDMA3 on this OMAP L138 LCDK?

Thanks
