C5000/6000 DSK and EVM

  1. I can't compile the demo programs that came with the board. I get a DSP/BIOS related error. What should I do?
  2. I'm confused about the interrupt jumper settings I need to make on this serial port daughtercard. Can you explain what they are for and how they should be set up?

  1. What's the difference between the model F2812DAQ, the F2812DAQ-6 and the D2812DAQ8x8?

C5000/6000 DSK AND EVM FAQ

  1. I can't compile the demo programs that came with the board. I get a DSP/BIOS related error. What should I do?

    This problem occurs because the version of DSP/BIOS used to create the demo programs is not the same as your version. To fix this, it will be necessary to remove the .cdb file from the project and create a new one from scratch. This is a simple procedure and is described in our Application Note AN-14.

  2. I'm confused about the interrupt jumper settings I need to make on this serial port daughtercard. Can you explain what they are for and how they should be set up?

Because the serial port daughtercard can operate with several development systems from the TI C5000 and C6000 series, it was necessary to create a flexible interrupt routing system. The C5000 series of DSP ICs have negative edge triggered external interrupt inputs, whereas the C6000 series has positive edge triggered external interrupt inputs. Also, each DSK/EVM has slight differences regarding the location of the interrupt lines on the Peripheral connector. Therefore, the interrupt routing system allows the following:

  • Interrupts from each serial port can be routed to any external interupt on any DSK/EVM.
  • Either positive or negative edge triggered interrupts can be configured.
  • Interrupt signals from the UART devices can be combined into a common signal, and routed to one of the EVM/DSKs external interrupt inputs.
  • Interrupt signals from different serial channels can be individually routed to different interrupt inputs.

Details of configuring these jumpers can be found in the C5000/6000 Serial Port Daughtercard Technical Reference Manual.

F2812 AND F28335

  1. What's the difference between the model F2812DAQ, the F2812DAQ-6 and the D2812DAQ8x8?

    The basic data acquisition daughtercard for the F2812 eZdsp dev. system is
    the model LR-F2812DAQ. This card provides 4 A/D channels and 8 D/A channels
    as well as a high speed (921.6 kbps)RS-232 port, and other misc. features.
    If you need more A/D channels, you can order the option: LR-F2812DAQ-1.
    For this option, we add components to the LR-F2812DAQ here at the factory which makes the board have a total of 8 A/D and 8 D/A channels.

    Now, if you need *more* than 8 A/D and 8 D/A channels, you can order
    the LR-F2812DAQ-6 option. This option is actually another board which plugs 
    into the first board. So you will have 3 boards stacked together (F2812 eZdsp, LR-F2812DAQ, and LR-F2812DAQ-6) and have a total of 16 A/D and 16 
    D/A channels. 

    The model LR-F2812DAQ8x8 is physically the same board as the LR-F2812DAQ-6. It is listed twice on our website so that customers who already own
    a model LR-F2812DAQ can now purchase this piggy back board to get 8 more
    A/D and 8 more D/A channels. If you know up front that you will need 16 A/D and 16 D/A channels, then you would simply order the model LR-F2812DAQ
    *with* the LR-F2812DAQ-6 option.

    It is important to note that neither the LR-F2812DAQ8x8 nor the 
    LR-F2812DAQ-6 board will work if plugged into the eZdsp board. 
    You must have the model LR-F2812DAQ board in order for the piggy back
    board to work.
