C6424 EDMA3 programming

sudheer thota

Hi,,,

I'm using the ti provided example program for D6437 for reference to program low level edma driver for c6424 EVM.

https://gforge.ti.com/gf/download/frsrelease/174/2134/tto_lld_6437.zip

Everything looks okay but i'm not able to receive EDMA interrupts. When i tried, McBSP interrupts are working with out EDMA.

Let me know if you see something wrong with the attached program.5417.tto_lld_6437.zip

Sudheer thota,

EDMA3_LLD package will support for DM643x and C642x.
You have mentioned the tto_lld_6437.zip used for C642x.
However that zip file have list of examples.
You are not mentioning, which example used for C642x.
You can get target examples from spectrum digital for EVMC6424.
And also go through the EDMA3 user guide as mentioned link below.
http://www.ti.com/lit/spruem5 for TMS320C642x DSP
http://www.ti.com/lit/spru987 for TMS320DM643x DMP
If you used evmc6424.gel file, verify EDMA disabled or not.
