  • Forum Post: EDMA to SPI - No Activity

    nkeddem
    I am attempting to ulitize the EDMA to loop out data that I have in a 1d array on a OMAPL137. I am getting no activity on the SPI line when I execute my program but if i manually change the data found in SPIDAT1 I get line activity. It is almost as if I am missing something in my EDMA configuration but...

    I'm using MV Linux on the ARM9 and DSP/BIOS on the DSP side of the OMAP-L137. I need to DMA from the SPI1 to memory on the DSP side. (MV Linux will not be able to keep up with the real-time control requirements.) The number of 16-bit transfers is variable from one transfer to the next, and the...

    Thanks. Using this info I found nm6x. However, when I entered its location into RTSC, the following two screens were the same. That is, on step 5 of 6, I get two tables: one with blank Config Name and another with blank Return values. I don't know if I need to put anything in there. I hit the Next...

    Hi Mariana By chance do you have any idea of where I could acquire the DSKDA830 User Interface Board, I already called SpectrumDigital but they said the only way to get it is thru TI and you can only buy it as a whole kit. I have already purchased the OMAP-L137 EVM so I´m not interested in...

    I'm using the OMAP-L137. SPI 1 will be connected to an ADS8330 ADC. Commands to drive the ADS8330 will be output via SPI 1. nCONVST will be a GPIO pin from the OMAP-L137. Additional setup and control associated with the ADC will be via 6 GPIO pins. One of these will be a GPIO input, probably an...

    I am developing an IUNIVERSAL-derived codec for the OMAP-L137. Using CCS, I've developed a library project for the codec and a separate project for main and some background tasks. Both build. Now I'd like to test them. {For test purposes, the library and tasks just turn on some test LEDs right...

    My correspondance with my TI rep suggests that you and he disagree on this: "When Engine is opened, the dsp image gets loaded and the DSP starts running. The Codec Engine remote server running on DSP waits for the ARM to instantiate a codec instance using _create(). You may however, create static...

    I am looking for the documentation that describes how to program the timers on the OMAP-L137. I have omap-l137.pdf which describes that there is 1 64 bit timer (or 2 32 bit timers), lists the registers, but does not describe how to use the timers or program the timer clock.

    Each time I add more GT_ trace calls in my app, the trace messages from Engine_open seem to suggest that the code is making it further without error. Since I'm not making any other changes, this screams of memory partitioning, stack, heap, etc errors. My target board has twice the SDRAM as...
