    Hello,

    1. That is correct, whereas the ZED role would be able to use external flash or dual images, the ZC/ZR roles can only utilize an external flash option.

    2. Typically MCUBoot is being used for OTA, and thus the imgtool is used to create a *.bin application image which could then be combined with the mcuboot.hex using SRecord to create a production image (ignore the BIM references as this is for a separate solution).

    3. An upcoming SimpleLink F3 SDK will include Zigbee OTA examples which will demonstrate how the projects can support MCUBoot usage.

    Your E2E post title indicates serial bootloader usage, not OTA, and if this is the case then MCUBoot is not necessary and you should be looking at the TI_CC2340_Linux_SBL tool

    Regards,
