Part Number: AWR1642

Hi Team,

Customer placed two programs in the flash chip. The address is program 1:0-512k and program 2: 512K-1024K. May I know how to load a second program without damaging the Bin file without using the bootloader?

Thanks.

    Hi

    The bootloader will only boot one program. I think you will need a secondary bootloader to load a second program.

    I am looping in our sw team

    thank you

    Hi Annie,
    To boot the selected image from the sFlash you must need to use secondary bootloader (SBL). Primary bootloader always starts reading from zero offset of flash chip and it jumps to every 512KB if doesn't find valid image at last offset.

    Conclusively you can use SBL to select the image to boot without damaging any image.
    You can find reference SBL in mmWave SDK (packages\ti\utils\sbl), go over the SBL document to get to know its functionalities.
