  • Forum Post: What is the right memory choice for different segments on DSP C6748 with 128M DDR

    Pavel Livshits
    Hello, I have two questions about dealing with memory on DSP C6748 with 128M DDR. My first question is about the right memory for different types of segments. First I tried to put everything on DDR with 64K L2 Cache but then my project refused to run to main. So I had to play with the entire segment...

    Hi, I'want to connect a usb webcam to L138 EVM kit. I'm using the C6748 part of the omap processor by CCSv3.3. I have looked to the examples of the BIOSUSB. However there isn't any example about that. Is there any application note? Or is it possible to connect usb webcam by this way?

    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...

    Hi everyone, We're trying to set a C6748 up as an I2C slave. Eventually we'd like to go to SMBus rather than plain-old I2C, but for now we're focusing on I2C slave support as a more achievable goal. The PSPdrivers package seems to have I2C example code, but only when using the device...
