CC1312PSIP: OAD

Part Number: CC1312PSIP

Tool/software:

Hi,

I am writing TI15.4 OAD server code to embed into a CC1312PSIP using the rfOAD and Linux applications as a basis.

Can you tell me where the the image identify payload gets added to an OAD file? I have looked through the oad_image_tool.py and oad_write_bin.py but I cannot see where this header gets created. 

/* Image Identify Payload */
typedef struct __attribute__((packed))
{
    uint8_t   imgID[8];       //!< User-defined Image Identification bytes. */
    uint8_t   bimVer;         //!< BIM version */
    uint8_t   metaVer;        //!< Metadata version */
    uint8_t   imgCpStat;      //!< Image copy status bytes */
    uint8_t   crcStat;        //!< CRC status */
    uint8_t   imgType;        //!< Image Type */
    uint8_t   imgNo;          //!< Image number of 'image type' */
    uint32_t  len;            //!< Image length in bytes
    uint8_t   softVer[4];     //!< Software version of the image */
    uint8_t   isDeltaImg;     //!< Indicates if payload is delta image  */
    uint8_t   toadMetaVer;    //!< Turbo OAD header version  */
    uint8_t   toadVer;        //!< Turbo OAD version  */
    uint8_t   memoryCfg;      //!< Flash configuration used */
    uint32_t  oldImgCrc;      //!< CRC of the current app image  */
    uint32_t  newImgLen;      //!< Length of the new app image  */
} OADStorage_imgIdentifyPld_t;

The reason I'm looking at this is because the BIM and META versions are causing me an issue in oad_storage.c when I upload a bin file to the server. How do I make sure the BIM and META versions match?

    // Ensure the image is built with a compatible BIM and META (ensures the image is meant for the right bootloader too)
    if(idPld->bimVer  != currentImageHeader->fixedHdr.bimVer  ||
        idPld->metaVer != currentImageHeader->fixedHdr.metaVer )
    {
        status = OADStorage_Rejected;
    }

Thanks,

Andy
