Other Parts Discussed in Thread: OMAP3530

Dear all:

          Recently I have compiled NK.bin use based on the latest OMAP3530 WINCE BSP version                BSP_WINCE_ARM_A8-1.00.00.11, but there is no serial output messages of NK.bin and display also no signal when I booted omap3530 from SD card . Some messages before jump to NK.bin are as follows:

BL_IMAGE_TYPE_BIN

Download file information:

-----------------------------------------------------------

[0]: Address=0x80002000  Length=0x0170b394  Save=0x80002000

-----------------------------------------------------------

Download file type: 1

...................................................................................................................................................................................rom_offset=0x0.

..ImageStart = 0x80002000, ImageLength = 0x170B394, LaunchAddr = 0x800114E0

Completed file(s):

-------------------------------------------------------------------------------

[0]: Address=0x80002000  Length=0x170B394  Name="" Target=RAM

ROMHDR at Address 80002044h

Launch Windows CE image by jumping to 0x800114e0...

"Launch Windows CE image by jumping to 0x800114e0..."  is the last output messages .

Can everyone tell me the reason?

Thanks in Advance for your support!

    Nifeng,

    I am assuming you are trying to use platform builder to download the image in the first scenario (using LAN port). If so,

    • Are you seeing output messages in the "output" window of platform builder once the image has come up? This would mean that kitl is enabled in your build and hence, all retail messages are redirected to platform builder port.
    • Do you see display on LCD coming up with calibration screen?
    • Is this a retail or a debug build?

    Regarding SD boot,

    • Does the SD card contain the MLO generated for your specific build? You would need to do a retail build for MLO to be generated in your flat release directory. Not getting display up and running might indicate that the MLO is not the latest one.
    • Finally, are you able to get prebuilt images to work on your board?

    Regards,

    Aparna

    Nifeng,


    Try enabling retail message using Eboot option (Enable/Disable OAL Retail Messages).

    To Aparna:

         1. The prebuilt images from BSP also can not work on my board except MLO and ebootsd.nb0.

         2. The NK.bin is a retail build .

        3.  LCD seems no calibration screen 

        4. all retail messages are redirected to platform builder port -------if so , how can I disable KITL and let the retail messages output to the serial-port。

     

        Thanks a lot

    Hi, nifeng,

     

    You can disable KITL by going to Osdesign Property in Platform Builder, then go to Configuration Properties -> Build Options -> uncheck Enable KITL.

    Nifeng,

    -  I assume you are trying this on the Omap3530 EVM (and not on your custom board). Which revision of the EVM are you using (Rev G is the one you should be using). Can you also confirm the Rev of your processor card and the Rev of the Power Module. These are daughter cards on your board (these are on the reverse side from the LCD).

    - Were you able to successfully use this board with any earlier version of the BSP? 

    - If the EVM version is the above question is correct, can you try one of the prebuilt images from BSP 6.14.01 demo release  (this is available on the TI site) and use the boot from SD card option.

    This will help narrow down the problem.

    Thanks to Jatin Jain.

    1. I have tried the BSP on my custom board , but most of the custom board should be the same to the EVM.

    2. I have just a one BSP and no other version . The version is BSP_WINCE_ARM_A8-1.00.00.11.zip. I just donot know whether it is right

     

    Thanks

    If you have an EVM could you first try it on the EVM and make sure that the prebuilt images in BSP_WINCE_ARM_A8-1.00.00.11.zip work fine before trying it on your board. This is a working combination and hence if this does not work for you there is something wrong in the procedure you may be following. Let's start from a known configuration first before bringing in more variables (such as your custom board even if it is very similar to the EVM).
