EDMA LLD library included in EZSDK 5_02 problem

Bendney Yu

platform: C6A8168

develop tools: EzSDK 5_02_02_60

edma3 lld: edma3lld_02_11_02_04

when I use edma3 debug mode, it passed, but release mode failed. I read the release document, it's said ping pong example fails for some cores in release mode.

If all ping pong mode including example will fail in this EDMA LLD library?

On which core are you trying run? Are you running the examples provided with the edma package or your application?

Can you specify where and what error you are getting?

The limitation mentioned was on the multicore dsp platforms it should work for C6A8168.

Parased,

I'm initialize edma driver for mcasp tdm mode data receive and transfer, so when I using edma debug library, the edma and mcasp both initialize correctly. When I using edma release library, mcasp get rsrctl (receive and transfer data contrl status) failed! There don't have any other error happened.
