    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...

  • Forum Post: McSPI0 and pad configuration

    DV
    I am trying to configure SPI 0 in master mode. I know the mux pads need to be set to 0 for SPI function, my question is do I need to also program ..say the clk pin pad as OUTPUT (master mode) and the MOSI as OUTPUT and MISO as INPUT... or is this automatically set based on function mode 0 being set...

    Flamingo
    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...

    Can anyone tell me what the "local" in the pspiom/spi code is in reference to? I'm using the OMAP_L137. I hope to hook SPI1 to EDMA to receive data. I thought the example Spi_edma.c would be a good place to start. Also, I notice that the intent of the example is to have both transmit...

    Flamingo
    (OMAP-L137, DSP side) With previous forum help (Thanks, Brad), I have debugged memory-to-memory transfers of 250000 16-bit words using an A-Synchronized transfer. I receive the transfer complete interrupt as expected. Note that this required the use of BCNT, BCNTRLD, and CCNT because of the large number...

    I have code: if (SEM_pendBinary(&SEM_collect, DMA_Timeout) == 0) I've been using this for a while, but now I'm trying to glue the DMA to the SPI. The transmit events are not occurring, so the DMA transfer does not occur. Although I know I need to debug that, I'm concerned that the...

    Flamingo
    I'm trying to get DMA running with SPI transfers on the OMAP-L137. The documentation suggests that I could be starving a DMA. That is, that the receive and transmit DMA transfers won't normally occur interleaved between each ACNT event. I'd like to chain the two. I would like the chaining...

    Flamingo
    I vaguely remember that EDMA wants things on 128 byte boundaries also. As a result, everything that I was using for a source or destination for EDMA transfers was on a 128 byte boundary (unless it was a HW register, in which case it was what it was). In one case, I had a single 32 bit value that was...

    Stephen Turner
    We have scoped the SPI clock and have discovered that each SPI byte read takes ~160ns (correct for 50MHz SPI clock). Then there is a ~1us delay between the next SPI read. SO the question is whats going on here?. Is the mDDR not setup correctly?. Is it the fact that (we believe) the L2 cache is not enabled...
