CCS/TMS320DM6467T: Problem with emulator connection to DSP core in ccsv8

Part Number: TMS320DM6467T

Tool/software: Code Composer Studio

Hi everyone

I'm newbie in c6000 and davinci series processors. I'm working on a custom designed DM6467T Board. 

I'm trying run some not linux based program on it. some examples codes, source and header file are available on the Spectrum Digital site for ccsv3.3

After converting project to ccsv8 based project, ARM core is working well but DSP core can not connect and dialog box says target  is held at reset.(while target is not in reset )

within gel files is noted that this gel file is written for ccsv3.3. I dont know how to rewrite them for ccsv8.

I'm looking for solution or other example codes that can help.

    This message means that DSP core need some additional initialization. Make sure you are running all DSP related init functions from GEL files (evmdm6467_arm.gel and evmdm6467_dsp.gel). There are GEL functions like DSP_Boot_from_L2_ram(), Setup_Psc_All_On() etc. And make sure this GEL functions are running successful.

    You might also try if below GEL files will be working fine for your board:

    Thanks for reply

    It worked with the GEL file within your link and ccsv3.3

    Is there any other source code or example for DaVinci processors somewhere? 

    I'm well experienced with c2000 dual core MCUs and there are a lot of code example in ti website for them, but i can not find the same thing for c6000 and DaVinci processors.

    Best Regards.

    Ali,

    In this link, we have ZIP file:

    Target Content - Includes source code & tests for the Davinci™ HD1080p EVM.

     

    You can also check appl notes:

     

    And Linux SDK:

    launching debug session for the "evmdm6467_v1_revf"  in ccsv8 gives the following GEL output.

    (it can not execute  "boot_dsp_from_arm(0x11800000)" . the same procedure in ccsv3.3 is done successfully)

    In general, ARM is the master so you need to connect ARM core first then try to connect DSP core then load the code on it. When you connect ARM core, the ARM gel will initialize all the peripherals on board and wakeup the DSP. Are you align with this?

    Usually the GEL file for the ARM will have a routine to release the DSP for reset. So you need to connect to the ARM first and run the GEL routine to do this (normally from the 'Scripts' menu). Sometimes it will automatically call this routine when you connect the target. In any case one the ARM releases the DSP from reset, you should be able to next connect to the DSP and access it.

    Check also below e2e threads:

    Hi Pavel,

    Thanks for your attention

    Yes,

    Seemingly the problem is with "DSP_Boot_from_L2_ram()" in the ARM GEL File. I replaced with by "DSP_Boot_from_DDR2( )" and connection was established successfully. Can you understand where is the problem?

    Best Regards.

    Ali,

    I can provide you below debug hints:

    - As you are using DM6467T, which is the DaVinci HD1080p – in this case, you shouldn’t be using the evmdm6467 but instead the davincihd1080p GEL files – automatically configured by the setup EVMDM6467T.

    - Looks like it is GEL memory map issue. You can update CCSv8 evmdm6467_arm.gel file, to make sure that memory address is writable

    /* DSP RAM */
   -  GEL_MapAddStr( 0x11818000, 0, 0x00020000, "R|W|AS4", 0 );   // DSP L2 RAM/Cache
      + GEL_MapAddStr( 0x11800000, 0, 0x00020000, "R|W|AS4", 0 ); // DSP L2 RAM/Cache
    GEL_MapAddStr( 0x11e00000, 0, 0x00008000, "R|W|AS4", 0 );   // DSP L1P Cache/RAM
    GEL_MapAddStr( 0x11f00000, 0, 0x00008000, "R|W|AS4", 0 );   // DSP L1D Cache/RAM
