How to access External Memory for the "Mistarl OMAP 3530 EVM Main Board REV D".

Other Parts Discussed in Thread: OMAP3530

Hi,

I’m  working on Mistarl OMAP 3530 EVM Main Board REV D with OMAP Processor Module OMAP 35xx REV B on it along with CCS 5.1 through BackHawk USB 560BP Emulator.

It’s using Samsung Onenand K5W1G1GACM-DL60

 

  1. Able to acess internal memory from addr 4020 0000
  2. Added gel file “omap3530_cortexA.gel”  at new target congiuration, which is supported by CCS 5.1.

      According to my understanding this main “omap3530_cortexA.gel”  internally calling the following gel files.

  •  CortexA8_CrossTrigger.gel
  • cortexA8_util.gel
  • etm_cortexA8_registers.gel
  • omap3430_prcm_clock_configs.gel
  • omap3430_reconfigure_firewalls.gel
  • omap35xx_resets.gel
  • OMAP35x_AM-DM37x_sdrc_config.gel

 

Issues::

  1.  I tried to access external memory at the addr  0x0000 0000 and 0x8000 0000 which was producing error :: Data Verification Error.
  2.  How to access external memory / ? any memory address for it?
  3.  Is there any other gel file needs to be added  for this board ?

    On OMAP3530 the external memory is mapped at 0x80000000 and you MUST configure SDRC in order to access it. The SDRC configuration must be happening in "OMAP35x_AM-DM37x_sdrc_config.gel", so you just check whether code from this gel file is getting executed or not.

    Thanks,

    Hi Vaibhav,

    Thank you so much for your concern.

    I followed as you mentioned.

    1. Changed the External Memory Address 0x8000 0000. Still the error is same (PFA "LoadPrgmError.JPG")

    2. Checked OMAP35x_AM-DM37x_sdrc_config.gel, Code is passing through the gel. (PFA "SDRCInitilization_Done_for_mDDR_Samsung_K4X51323PC.JPG")

        We can see the "SDRC initilization for mDDR_Samsung_K4X51323PC completed" statement at console.

    Please verify cmd and gel files attached. (OMAP3530.cmd and OMAP35x_AM-DM37x_sdrc_config.gel).

    As per my observation ::  

    The Mistral OMAP 3530 EVM Main Board REV D with OMAP Processor Module OMAP 35xx REV B is using Samsung Onenand K5W1G1GACM-DL60 but the memory configured in the ***sdrc_config.gel file is for "mDDR_Samsung_K4X51323PC" ( /*Configure only memory on CS0*/). Is this mismatch causing the Data verification error ?
