Hi,
I want to send audio data from mic to EVM board , then use a audio talkthrough(using ping pong buffers) and send from EVM board to another PC via ethernet cable (UDP protocol). For this, I am combining the
1.EDMA ping pong test (main.prj) in the directory :C:\Program Files\Texas Instruments\edma3_lld_01_11_03_01\examples\edma3_driver\evm6747\ccs3 (dma_ping_pong_test.c) with
2. Cfgdemo.prj from the path: C:\CCStudio_v3.3\ndk_2_0_0_0\packages\ti\ndk\example\network\cfgdemo\evm6747
I am using ccs v 4 and EVM OMAP L137/TMS320C6747 on Windows 7 PC
When I run the EDMA ping pong test, it passes successfully. But when I merge EDMA ping pong test with cfgdemo.prj(ie. I copy EDMA code and paste into cfgdemo code), then, the EDMA initialization passes successfully, but during data transfer via EDMA, the program flow goes to HWI_INT8 and never returns back.
Do I need to go to the .tcf file (evmboard.tcf) and change the scheduling/HWI/HWI_8 from HWI_unused to _ECM_dispatch? (also do I need to change interrupt selection number?)
I have attached the projets herewith.1538.ToTI.zip
thanks for your attention.
