RM57L843: Question about unsigned 64bit data, DATA_SECTION and HEX

Part Number: RM57L843

Hello TI engineer:

   My goal is to place a volatile const uint64_t variable at specific FLASH address (GOLDEN_CRC area, address 0x001FFFF8~0x001FFFFF).

My cmd file design as following:

The global const variable definition as following:

My question is that the HEX file is not as the above, the HEX is as following:

just 16bit contents are in HEX(bit0~bit7, and bit32~bit39 of #define).

I tried several define-value tests, proved that only bit0~bit7, and bit32~bit39 of define-value is reflected in HEX file.

Thanks a lot!
