Hi All, I have a problem for initialize McBSP to interface with ST-BUS(4 channels); that is time slot miss-align, two slot are shifted. My McBSP is serviced by EDMA and I've verified that EDMA transfer from DRR is correct but transfer to DXR makes this pro

I have not found wherever in docs how many EDMA requests are submitted per a single PCI transfer and how to determine and set up properly the PCI EDMA queue length. I supposed that must be only one request but it seems to be not actually true. In my application I always have a problem with lost PCI t

Hi All, I have configured an EDMA channel Rcv data from the McASP. My aim is to get some 80 samples in a buffer and then send an interrupt to the CPU. The EDMA successfully transfers one sample at a time and generates a CPU interrupt after each sample. I have a very basic question: Is it possible to buffer 80 samples before sending a CPU inte

Dear all, I have already implemented EDMA-EMIF to read Frame Buffer ALL422B using asynch 8-bit which come from CMOS Sensor. I found out that the maximum speed of EDMA transfer is 4.12 Mhz and the lowest speed is 688 kHz by change the EMIF parameter. According to this maximum

Dear Guys, Thanks your help in advance. Now I met one question about EDMA transfer data as follows. I want to transfer one whole column pixels from external memory image (size: 32*98304(R*C) )to internal memory,every pixels takes up2 bytes. I set the following parameters for EDMA: config.opt = 0x00100004 | (Inttcc <

Hi there, I am working on a project using timer and EDMA with ping-pong buffer structure for continually collecting samples on DSK6713. I can configure the HWI in the .tcf for the timer, but I did not find where to configure the EDMA using CSL as described in http://www.ti.com/lit/an/slaa257/slaa257.pdf. In my CCS 4.2, when I open the .tcf file, I only have "System, instrumentation, sc...

Hi, I'm using EDMA to transfer a block of data from external to internal memory. I've setup the EDMA with the proper parameters, set the TCC, enabled the TCINT, etc... I've also defined an interrupt service routine, which sets a "transferComplete" variable to 1 to notify the processing task that new data is available. I registered this ISR into the "Hardware Interrupt Service Routine Manager...

Hi All, I am using the DSK6455 as my development platform. What I am doing now is to setup the EDMA channel so that the EDMA will handle data read form MCBSP and then transfer out form the same MCBSP channel. In the very beginning I try to use polling to poll the Rx and Tx ready flag of MCBSP channel to handle the data receive and transmit. And it prove that my MCBSP setting is correct. ...

Hi All, I am using the DSK6455 as my development platform. I try use the EDMA to handle the data transfer via the MCBSP channel. I can transfer the data perfectly if I use polling which poll the transmit and receive ready flag of the MCBSP interface. I want to use the EDMA but not polling to handle the data transfer. My program do not work when I test it. The problem is that the EDMA co...

Hello Everyone, I am trying to do a *Peripheral Device Transfer (PDT)* from an FPGA *(FIFO on a Virtex-5)* to a *DSK6416*. The data is 8-bit and fifo depth is 32. The FULL flag of the FIFO will trigger a PDT (an EDMA event). The FULL flag of the FIFO is connected to *EXT_INT7* which will trigger the EDMA event *EDMA_EVT_EXTINT7 ( channel # 7 of C6416T ).* * * The FIFO worked perfectly...

Hello, I am using McBSP configured as a SPI slave to transfer data from C6713 to a computer with EDMA feeding 128 element frames into McBSP and EDMA transfer complete interrupts invoking new frame transfers. The problem is that during almost every frame the transfer stalls at some point resulting the rest of the received frame to be zeroes. The transfer recovers when the next frame boundary nor...

Hi, Phil Thanks for your answer. You mean probably even I use DAT_copy(), it is still executed by the DSP core instead of using EDMA hardware. Then how can I ensure it is executed by EDMA hardware and let the DSP core do other processing at the same time?

Hi Mayank, first of all, which target processor do you use? I'm using a C6416, maybe the configuration for C62x and C67x processors is different from mine, but I hope this will help you though: There are two different types of starting an EDMA transfer, event tr
