Hello, I am playing a tone on TMS320C6713 thanks to McBSP & EDMA with Ping- Pong stuff. That works fine. Now, when i press a DIP switch, for some reason, i need to change the buffer size and to continue the playback. I guess i need to stop the EDMA, clean it u

Hi all; I am testing UART in EDMA interrupt mode.My problem is after linking edma transfer to a new table,I send data continously. But I want to send data when I ask it to, how can I do to control edma when I start or stop sending data .Athough I know that I can stop transferring by linking to a null table:EDMA_link(hEdma14, hEdmadummy);but when I want to start again what should I do? he...

Hello all, I am a rookie in DM642 platform. These days I am tangled by a EDMA problem. I found that DAT_copy will not work properly when L2 cache is turned on and source data and/or destination data is resided in off chip memory. In TI's document, it is said that EDMA operation can't guarantee the consistency between L2 cache and SDRAM. So I call function

Hi, I was wondering if you could help me sort out a problem I'm having with my EDMA transfer. I'm working with the C6711DSK and the AIC23EVM Codec. The problem is that when I use EDMA transfering, I'm losing every second input and output sample. I have the sample

I've got a sequence of items that I'm trying to accomplish with a linked EDMA sequence. I believe that linking and chaining are two completely different things, and I'm trying to use linking, with the last item in the linked list set to produce an EDMA completion interrupt. I've got error handling that makes sure that the table entries are allocated correctly, and the initial channel op...

Hi, I'm working with a 6713B. I have a situation where src and dst of memcpy point to ext. SDRAM. When I simulate this and do assembly-single steps through memcpy I see that every step a data transfer is made. What if a EDMA wants to access ext. SDRAM at the same time? Which one is stalled: EDMA or CPU? TIA Gustl _____________________________________

Hi, which configuration of arbitration register is the best one for EDMA to McBSP transfer? I have problem... when CPU start write into L2, EDMA-to-McBSP transfer starts to be non-continual. I've tested all combinations, but no improvement. There no other data transfers.

We have been running a software UART through the McBSP on a C6711, based partly on the example code provided by TI. This setup uses the EDMA to send UART-format data to the McBSP for transmission. I ran into a problem with the EDMA doing this, and found a wo

Has anyone an example code using C6711's McBSP with EDMA under DSP/BIOS II? Specially I am interested in the initialization sequence. I have written a test program which initializes McBSP in Digital Loopback mode and EDMA to feet the transmiter and read the receiver. It works f

Hi everyone, Is it possible to access external memory without using EDMA. I would like to pass a buffer pointer located in external memory to a function call without configuring EDMA. The DSP i am using is C6713. I would configure whole L2 as SRAM (256K) i.e., no L2 cache. Any comment will be appreciated.

Hi, I use EDMA to transfer samples from two channel 12-bit A/D converter (DSP STAR ADDA module) through EMIF into 2 buffers in internal SRAM. EDMA is triggered by EXT_INT7 and moves two 16-bit samples on each event. Buffers are switched after completing a block of 2*2560 samples using linked PARAM presets. This program runs fine if NOT using BIOS. When I use the same EDMA presets in ...

Is there any document\manual which explains how to generate interrupt from an EDMA controller,any sample project will be more helpful.Further how can we generate interrupt from host(arm9)to target processor DM642. EDMA channel 0 supports host to DSP interrupt but i don't know how to use that. Please refer any manual. Regards, Mayank

Hello, could you please help in the following issue? We're configuring EDMA in the TMS320C6455 in order to send/receive data to/from FPGA via EMIFA bus. We've found a problem in the EDMA configuration when we are trying to read from FPGA. We detect in the time diagram that every 20 cycles, the ADS signal goes high, so the signals CE and OE goes high too. We don't know if there are some type of li...

Hello everyone, I'm a newbie in DSK C6713... I'm working in some project and I only use codec (DSK6713_AIC23_read & DSK6713_AIC23_write) for data transfer. And it works, I mean the input can be heard by using speaker in output port. But I found that there's another way to transfer the data, by using mcbsp or edma. My question is, when do we have to use mcbsp channel or edma module for data (in...
