AWRL6432BOOST: AWRL6432 sensor

Other Parts Discussed in Thread: AWRL6432

Hi,

The AWRL6432 sensor does not have a permanent memory (flash) in itself. It works by copying the code loaded onto the serial flash into its own RAM. External flash memories can be easily read by others. In this case, is there a way to secure the user software from being copied without using an external MCU?

    Hi,

    We do have "Authenticated boot" versions of the device that can read an encrypted image from an external flash device. We also have tools that can generate the encrypted image and flash it to device.

    Please contact your TI Sales representative to inquire about more detailed information.

    Regards,

    Tim
