  • Forum Post: BIOSPSP audio example for C674x

    Yan8622
    Hi, The audio example given in the C674x BIOSPSP package would stop running if the audio processing between SIO Rx and Tx takes too long. I think a better handling of this situation would be to skip the a few audio frames but without breaking anything. Any advice how to do that? Thanks

    James Jurack
    Sometimes (I have been unable to isolate the conditions -- it seems to come and go with time), gio_write will return -13, when working with the SPIFlash driver in BIOS/PSP for the C6748. I have been unable to find any reference to this error code in either the documentation or the source code. Does anyone...

  • Forum Post: GPIO interrupt priority using PSP driver with DSP/BIOS

    Frederic Leger
    Hi, On our hardware a GPIO interrupt (bank 5) is used to request a realtime data transfer on the EMIFA bus to an FPGA driving lots of ADCs. The rate can reach 80kHz. At present time, some other activities of the DSP software (mainly UDP/ NDK, UART)are causing extra delays on the interrupt response...

    Hi I'm using the Logic EVM with C6748 SOM and I'm investigating spi transfer. So far, I have spi working in dma mode. However, like a few others on this forum, I've noticed that there is quite a big delay between chip select and start of spi clock if CSHOLD is set. This delay is not present...

    Raghavendra Maddikery
    Hi Stefan, When you configure i2c in DMA mode of operation and if there is a NACK interrupt, you cannot recover back and continue further(perform another request - bufLen = 2u or more!!). The reason behind this is, In the dma mode of operation when the bufLen is 2, the EDMA will be programmed for...

    Hi Mark, Mark Monson Can I change the timeout for IOM reads after I initialize the driver ? Yes, you can do it. Mark Monson If I actually get a timeout the status of the IOCTL calls says they succeeded, but the UART driver never resumes reading packets So when you get a timeout,...

    Hi Stefan, Stefan Koehler Ok I understand the background of this problem now. Is there a function which can be called to do the operations the Callback normally does (resetting I2C and EDMA to allow to work with them again) Yes, you can do this!. But, since you have a specific requirement wherein...
