I'm writing my code in C64x simulater, I have a problem about the EDMA When I tigger a EDMA transfer by EDMA_setChannel(),the PQAx register! Each priority level has the same problem. Could you tell me why it occurs?? Thanks all!

Hi, I'm using EDMA to handle my McASP transfers. After these transfers I chained another EDMA to copy the timer0 to a variable. Both EDMAs have high priority. I use the difference between two timer values to calculate the sample rate of McASP. The Ethernet stack runs and uses only ext. memory. It doesn't use any EDMA or other DSP hardware. The only code that is connected to an IRQ ...

Hi all, I`m newbie to DSPs and I`m using TMS320C6711DSK. I want to generate a serial signal, which has 80 bits at 1MHz every 250 uscs. I want to use timer1 to prompt the start of the signal, and McBSP with EDMA to generate the signal. I'm able to make it once configuring the EDMA and McBSP properly, but I can't make it periodically, the EDMA interrupt is not generated. How can I do it?? Is i...

Hi, Using 6711. I have EDMA synchronized to EXT_INT4. During transfer complete ISR, due to some hardware testing I am receiving some false external interrupts which I do not want EDMA to pick it up. To fix this problem, I am using following sequence: EDMA_di

hi all: I have some troubles to use my EDMA of C6713 to recive and transmit my audio signal. I use edma to recieve and transmit my audio signal frames (128 points) independently. I hope each operation (R and X) give me a interrupt after done.and I give them different TCINTNUM. cause the edma has only one interrupt event,so when the programme run to the interrupt service function,how can...

Hello everyone! I am using the 6437 and add the edma to my project ,i just copy the example's bios configuration file into my project . The edma programme in my projects just used for cycling move some data for ddr2 to sram,but the edma programme only work in the first cycle,i know may be it caused by the bios file,but i don't how to configure the bios file,is anyone know ?

Hi there, I'm new in programming DSP's. I'm using the C6711DSK. At the moment i'm trying to set up a edma transfer to capture sound samples from codec/mcbsp. Therefore I used the link feature of the edma controller. I'm using the channel for McBSP0 (#13), c

Hi there, I am sending data to McBSP thru EDMA. I am using linked buffers to do this and this is working well. But I have disabled the EDMA in the interrupt so that the next buffer data doesn't get transfered till i have filled it up. Unfortunately this is not

Hi all: I want to trigger EDMA event1 by timer0_int. After setting the EDMA parameter(6 word from 101A0 0018 to 01A0 002F) and Timer0, do I need to set the other register ex: EER or enable EDMA_int ? In other words, what is the c

Hello friends: I left this one out on my previous post. I am curious to know whether or not the EDMA mechanism changed from C62x to the C64X processors. By reading SPRU190 (Peripherals Reference Guide), it seems it did not. The EDMA wait times on C64x for the exa

i run into a new problem,the video capture EDMA can't be trigered.i configure video port0,port A to capture a standard 8-bit BT656 video data from saa7113 encoder,continuous capture mode and to sent an interrupt request to CPU when a complete line is captured. but the edma interrupt can't be trigered,the edma interrupt service routine can't be executed consequently.when i set the correspond...

Hello everyone, I am using EDMA channels in TIC6713 and i am using CPU triggered EDMA's and some GPIO triggered EDMA. And there are sometimes when I use EDMA channels with different TCC number, and hooked the callback function hooked to this tcc number using inthook(tccnum,function). Right now the the function is called myedmaisr and then I com

We have had success using EDMA "chaining" (TI calls it linking?) in conjunction with a ping-pong buffer. One set of EDMA parameters sends data to the "ping" buffer and on completion automatically kicks off the EDMA to the "pong" buffer. Using this method you have almost the entire duration of the buffer collection to service the interrupt because the EDMA is now running on the "other" buffer....

It seems that the EDMA does not run at all (I am assuming this, by polling the Transfer Complete bit, which doesn't seem to be set at all). Basically all that happens is that I get an initial very short "blip" noise, i am assuming that if the EDMA worked and that I got the source address wrong or something like that, that I would at least get continuous noise. (But like
