CCS/AM3359: Creating an SPI bin file

HI Frank,

Thanks for the quick response.. The issue is that tiimage.exe does not create a header on the beginning of the bin file like when you run the post_build.bat file does. in the post_build.bat the tiobj2bin.bat is call. Hence the question in regards to the bootloader. In our older version of the bootloader the magic number is look for. in addition, the isdk_image.exe does add the header I'm looking for which is also part of the post_build.bat (after tiobj2bin.bat). Late yesterday I took the bin file created by 9.3 (enabling general options) and used the sdk_image.exe and that added the header. I loaded the new bin file and the board now boots correctly. I need to do some more test. However, my concern is isdk_image.exe was not in any of the doc reference is sent.

It seems to me that it would be nice to have the CCS tool create all the bin formats without need to run post builds or even conversion programs outside CCS. Of course this may not apply to all cases, however, having a baseline would be nice.

Thoughts?

Hi Frank,

OK, but that does not answer the question. Are you saying the PDK boot load does no look for the header file ( I have not check yet)? if it does then what is the path beyond tiimage.exe that does not have the header added?

Hello Frank,

Thanks for the help here. Rob is part of my customer base, it seems like the actual question is still not being answered. Please help address. I will try to clarify more below:

Currently Rob has a work around, but we really want to get the answer that is best. Currently they use a bootloader that looks for the heading info and check for the magic number.

 As stated (works):

-build the out file and bin file (using the GNU option to build bin)

-then run ISDK_image.exe to add the header with the magic number and other things

-Download this bin and it will boot.

What seems to be recommended – I believe

-Create bin and out as above

-Run tiimage.exe to create a spi version bin file

The problem is the tiimage.exe does not add the header info and going by the .c file too

Question:

In the PDK there is a bootloader.c (have not gone thru the code yet). Does it not look for the header file when booting out of the SPI chip?

Is there and PDK version of isdk_image.exe to add the header?

Hi, 

Please see <PDK>\packages\ti\starterware\bootloader\src\sbl_mcspi.c:

/* -------------------------------------------------------------------------- */
/*                 Internal Function Definitions                              */
/* -------------------------------------------------------------------------- */
static uint32_t SBLMcspiImageCopy(uint32_t *pEntryPoint)
{
    ti_header imageHdr;
    int32_t status = S_PASS;

    /* function to read the header. */
    SBLMcspiReadFlash(&gSblMcspiCfg,
                      SBL_MCSPI_IMAGE_OFFSET,
                      sizeof(imageHdr),
                      (uint8_t *) &imageHdr);

    CONSOLEUtilsPrintf("\nCopying Header of the image ");
    *pEntryPoint = imageHdr.load_addr;
    CONSOLEUtilsPrintf("\nCopying image from flash to DDR\r\n");

    /* Copies image from flash to DDR RAM */
    SBLMcspiReadFlash(&gSblMcspiCfg,
                      SBL_MCSPI_IMAGE_OFFSET + sizeof(imageHdr),
                      imageHdr.image_size,
                      (uint8_t *)(imageHdr.load_addr));

    return status;
}
