Hi Christoph,

Please refer to the following TI E2E post.

Hi,

Thanks for your post.

I don't think, there are examples for EDMA usage with the newest TI-RTOS & CCSv6 and again, there are no examples available for OMAPL138 boards with latest TI-RTOS, but available examples can be ported to other boards and devices. Please check the TI-RTOS porting guide as below:

http://processors.wiki.ti.com/index.php/TI-RTOS_Porting_Guide

If you plan to use TI-RTOS within Code Composer Studio v6.0 or higher, is it recommended that you
use the CCS App Center to install TI-RTOS. Please download the latest version of TI-RTOS as  below:

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/mcusdk/index.html

http://processors.wiki.ti.com/index.php/TI-RTOS#Examples

Kindly check the release notes as below:

Thanks & regards,

Hi Christoph,

there are examples for EDMA3 LLD driver for SYS/BIOS 6. I am not sure about the latest versions.

But I recently installed these versions:

BIOS 6.37.01.24

EDMA3 LLD 2.11.09.08

SysLink 2.21.02.10

Regards,

Jiri

Hi Jiri,

thank you for your reply. I found the example in the edma folder, but  I can´t watch the source files. I installed the 7.2.3 compiler in the meantime. When i want to open the files

Error retrieving content description for resource 'edma_drv_bios6_omapl138-st-sample/dma_chain_test.c'.

occurs, and i can´t watch the files. What do I do wrong?

Regards,

Christoph

Christoph,

after the installation you should get the directory like this:

I highlighted the files the most relevant to the building example

Have you got the same structure?
