OMAP-L137/TMS320C6747 FP-Starter Kit DSP/BIOS examples buildable, but not working

Other Parts Discussed in Thread: CCSTUDIO, TMS320C6747, OMAP-L137

Hello

first of all i have to admit that i am completely new to programming a dsp or arm not to mention the hybrid L137.

I am using CodeComposerStudio v3.3 and the basic examples like "aic3106" or the ones from the ndk worked fine.

But now i wanted to take a look at the examples of the DSP/BIOS.

I would like to create 2 tasks by myself, that have to communicate, and searched for an appropriate example.

To start slowly i opened  a "Basic"-example-program "Hello" for the "evmOMAPL137"

(directory-path= CCStudio_v3.3/bios_5_33_01/packages/ti/bios/examples/basic/hello/evmOMAPL137 )

I am able to open and build the example, but after i loaded it to the evm-board and start it, nothing happens.

I tried some other examples, with the same result. Opening and building works, but after they are started, nothing happens.

 

I would appreciate an answer telling me why this is happening, because without any error-Message while building or opening the examples, i do not know where to start searching for my mistake.

 

best regards Rico

    Not sure what you mean by "nothing happens".  The program fails to execute?  You open the User Log, but nothing appears there?

    With "nothing happens" i really want to say that nothing happens, except that the DSP is not in HALT anymore, i suppose all the test-samples i tried out, to prompt something via the standard out-"Window" (or user-log)  of the CCS,  the "Hello world"-example should have showed "hello world" but it did not..

    and i am not sure why .. the only thing that i can see, if i push the "run-button" is that the CPU is not in HALT anymore, but no effect of the program beeing executed is visually shown, even if there was a print in the main-function.

     to clarify the staement more:

    LOG_printf(&trace, "hello world!");

    does not result in showing hello world! ,like it is supposed to, and i am not sure where tosearch for the mistake, because compiling works properly.

    And without the possibility to take a look if, or which task is in progress, i am not able to validate if i understand how multi-tasking works on the OMAP

    Dear Rico,

    it is more than a year ago that you posted this message. Nevertheless, I just ran into the same problem.

    Did you ever find a solution? I have figured out my own explanation: The LOG_printf does only work in combination with

    a real JTAG interface, not with the USB emulator, right?

    Best regards,

    HT

    Ah, just found the solution: I needed to open a Message Log under DSP/BIOS->Message Log.

    Dear Ti Eval, please help me .... I am working with OMAP-L137/TMS320C6747 Float Point Starter Kit, but I am with some troubles in its use. The code composer V.3.3 does not have the driver for the USB port, so I changed to the code composer v5.0, but it can not run the examples. The following message appears: C674X_0: Trouble Writing Register PC: Error 0x00000006/-1176 Error during: Memory, Register, The IM memory request is not serviced by the HW memory system. This could be caused by the memory address specified does not exist in the specified memory/cache level. I read that you find the solution ... you could explain it to me? Thanks....

    Hi Caio,

    the problem may be than both ccs versions are not compatible for the samples/examples.

    The examples provided with OMA L137 Starter Kit are designed for DSP/BIOS 5.X and DspLink whereas CCS V5 considers DSP/BIOS 6.X and SysLink.

    You may convert your DSP/BIOS 5.X project into DSP/BIOS 6.X but SysLink is not supported by OMAP L137...
