EDMA implementaion

Rahul Sharma71

Hello All,

I am using DM814x with CCSv4.2.4.

I want to implement EDMA for optimization purpose to replace memcpy.
After downloading edma3_lld_02_11_03_02 package i linked libs in my project.I imported ccs project from the below folder

edma3_lld_02_11_03_02\examples\edma3_driver\evmTI814x

Then after building

edma3_drv_bios6_ti814x_st_sample_configuration & edma3_drv_bios6_ti814x_st_sample project i got build errors in edma3_drv_bios6_ti814x_st_sample.The errors are as follows

Severity and Description Path Resource Location Creation Time Id
unresolved symbol _main, first referenced in C:\ti\ccsv4\ccsv4\tools\compiler\c6000\lib\rts6740.lib<args_main.obj> edma3_drv_bios6_ti814x_st_sample line 0 1460628432047 14309

Can anyone guide me how to implement edma on DM814x or what mistake i m doing.

Regards

Hello,

In the package you could find EDMA_driver_user_guide pdf with path /edma3lld_02_11_05_02/packages/ti/sdo/edma3/drv/docs
It contains Installation Guide, building etc.

Hello Margarita,

Thanks for quick reply

I followed that guide.What i understood is that it is having pre built libs and i just need to link it with my project.After linking n importing sample project i m facing above issue.

Hello,

What about if you not use the prebuilds?

You could also use our CCS forum:

Hello Margarita,

It will consume less time if i use prebuild rather than CCS forum.

Is there any issue with prebuild??
