Generating Image with DUVM Disabled in Chain A

Disabling DUVM in one bootchain saves about 512M memory but DUVM is required to support OTA, so DUVM must be enabled in another bootchain.

This chapter describes how to generate the image with DUVM disabled in chain A. The workflow is:

For example, on p3663-01 in Linux:
  1. Create the DUVM enabled bsp_image:
    cd drive-foundation
./make/bind_partitions --oot_kernel -b p3663-a01 linux
sudo rm -rf ${PWD}/../out/bsp_images_enable_duvm
./tools/flashtools/bootburn/create_bsp_images.py -b p3663-a01 -B qspi -r 1 -g ${PWD}/../out/bsp_images_enable_duvm
  2. Create the DUVM disabled bsp_image:
    cd drive-foundation
./make/bind_partitions --oot_kernel -b p3663-a01 linux ENABLE_UPDATE_VM=n
sudo rm -rf ${PWD}/../out/bsp_images_disable_duvm
./tools/flashtools/bootburn/create_bsp_images.py -b p3663-a01 -B qspi -r 1 -g ${PWD}/../out/bsp_images_disable_duvm
  3. Combine the two bsp_image and merge the FileToFlash.txt:
    /bin/cp -r ../out/bsp_images_enable_duvm ../out/bsp_images
/bin/cp -v ../out/bsp_images_disable_duvm/642-63663-0001-001_TS2/flash-images/A_* ../out/bsp_images/*/flash-images/

    Edit ${PWD}/../out/bsp_images/642-63663-0001-001_TS2/flash-images/FileToFlash.txt, remove all partitions starting with A_, and copy all the partitions starting with A_ from ${PWD}/../out/bsp_images_disable_duvm/642-63663-0001-001_TS2/flash-images/FileToFlash.txt.

    For example:

    ${PWD}/../out/bsp_images/642-63663-0001-001_TS2/flash-images/FileToFlash.txt
