Getting started with Peripheral Example Quick Start - CCS V3.3

KV
Expert 1800 points


Board :- Custom F2812 (Typically same as F2812 eZdsp).  The 6 jumpers are placed as recommended in page 2-14 of the eZdsp F2812 technical reference.

Emulator :- XDS510LC.  Able to connect and disconnect successfully.

Hi,

I was trying to get started with peripheral examples for CCS V3.3 and has encountered an error while loading the first example - CPU- Timer.gel

I get the following error 

'C:\tidcs\c28\dsp281x\v120\DSP281x_examples\cpu_timer\Example_281xCpuTimer.gel': function 'OnReset()' already defined. 

While investigating I noticed that F2812.gel was already loaded when CCS has started. 

Could I know how to sort this issue and proceed with this example and also the other peripheral examples.

Thx

    It is very likely that the cc_setup utility that configures Code Composer Studio to the appropriate target platform for emulation has included the F2812.gel file.  You can do one of two things to address this:

    1) Invoke cc_setup and remove the GEL file from the configuration.

    2) Every time you invoke CCS, remove the default GEL file from the project before doing anything else.

    Brandon,

    Thanks for your support.  I appreciate it.

    As suggested I removed the default GEL file and loaded the CPU-Timer example.  This time around there are no errors.  Thanks for your direction.

    I have a query- would you suggest to try loading all the 25 peripheral examples, any precautions I need to take?.

    Let me know what you suggest.

    Thx

    I don't see an issue with running the peripheral examples, especially if it helps get a feel for some of the capabilities of the device.

    I would suggest that you take time to read and understand what the examples are trying to accomplish and verify intended/expected output before just going through one-by-one and load them on the device.

    Another suggestion is to read the DSP281x_HeaderFiles_QuickStart_Readme.pdf file in the .\doc directory.  This has some information to consider when running these examples from flash.
