+ "text": "Split Images\n\n\nDescription\n\n\nSplit images allow the user to build the application content separate from the library content by splitting an application into two pieces:\n\n\n\n\nA \"loader\" which contains a separate application that can perform upgrades and manage split images. The \"loader\" resides in slot 1.\n\n\nA \"split app\" which contains the main application content and references the libraries in the loader by static linkage. The \"split app\" resides in slot 2.\n\n\n\n\nGoals\n\n\nThe goal of split images is to allow a larger application to run along with large components of mynewt such as \nnimble BLE stack\n and \nneutron flash file system(nffs)\n.\n\n\nConcept\n\n\nIn a typical mynewt application, an application is contained wholly within an image slot. Typically there are at least two image slots since the image runs from one slot while uploading new code into the second slot. Each image is capable of erasing and uploading another image.
Each image is completely stand-alone; that is, each image contains all of the libraries and components that it needs. \n\n\nOn a typical 256 kbyte flash, a flash layout might look like this:\n\n\n\n\n\n\n\n\nName\n\n\nSize\n\n\n\n\n\n\n\n\n\n\nbootloader\n\n\n16 k\n\n\n\n\n\n\nimage slot 1\n\n\n108 k\n\n\n\n\n\n\nimage slot 2\n\n\n108 k\n\n\n\n\n\n\nscratch\n\n\n8 k\n\n\n\n\n\n\nFlash file system\n\n\n16 k\n\n\n\n\n\n\n\n\nNow, suppose the desired image contains:\n\n\n\n\n\n\n\n\nPackage\n\n\nSize\n\n\n\n\n\n\n\n\n\n\nnimble\n\n\n69 k\n\n\n\n\n\n\nos\n\n\n6 k\n\n\n\n\n\n\nlogging\n\n\n3 k\n\n\n\n\n\n\nimagemgr\n\n\n3 k\n\n\n\n\n\n\nconfig\n\n\n3 k\n\n\n\n\n\n\nnffs\n\n\n15 k\n\n\n\n\n\n\nnewtmgr\n\n\n7 k\n\n\n\n\n\n\n\n\nwhich total 106k. With an image slot size of 108k this leaves only a small amount of code space remaining for the application.\n\n\nHowever, we can see that these packages contain everything you need to upgrade and configure, so if we build a stand-alone loader
with these components, we can build the app as a split image and get the entire second image slot to store application code and constant data.\n\n\nWhen do I use split images\n\n\nIf your application fits into the available image slots, there is no advantage to using split images. In general, split images are harder to debug and more complicated to upload. However for a larger application, there may not be enough flash space to have two copies of the entire application. This is when split image becomes necessary.\n\n\nHow do I tell Newt I am building a split image?\n\n\nNewt looks for the variable \nloader\n in your target file. If it finds \nloader\n variable, it will build a split image. For example, \n\n\ntargets/app\n app=@apache-mynewt-core/apps/splitty\n loader=@apache-mynewt-core/apps/slinky\n bsp=@apache-mynewt-core/hw/bsp/nrf52dk\n build_profile=optimized\n\n\n\n\n\nshows an application called splitty which uses slinky as its loader.\n\n\nPlatforms\n\n\nSplit
image requires BSP support. The following BSPs support split images:\n\n\n\n\nnrf52dk\n\n\n\n\nLoaders\n\n\nThe following applications have been enabled as loaders. You may choose to build your own loader application, and these can serve as samples.\n\n\n\n\n@apache-mynewt-core/apps/slinky\n\n\n@apache-mynewt-core/apps/bleprph\n\n\n\n\nSplit Apps\n\n\nThe following applications have been enabled as split applications. If you choose to build your own split application these can serve as samples. Note that slinky can be either a loader image or a split app image.\n\n\n\n\n@apache-mynewt-core/apps/slinky\n\n\n@apache-mynewt-core/apps/splitty\n\n\n\n\nTheory of Operation\n\n\nA split image is built as follows:\n\n\nFirst newt builds the \napp\n and \nloader\n images separately to ensure they are consistent (no errors) and to generate elf files which can inform newt of the symbols used by each part.\n\n\nThen newt collects the symbols used by both \napp\n and \nloader\n in two ways. It
collects the set of symbols from the \n.elf\n files. It also collects all the possible symbols from the \n.a\n files for each application.\n\n\nNewt builds the set of packages that the two applications share. It ensures that all the symbols used in those packages are matching. NOTE: because of features and #ifdefs, its possible for the two package to have symbols that are not the same. In this case newt generates an error and will not build a split image. \n\n\nThen newt creates the list of symbols that the two applications share from those packages (using the .elf files).\n\n\nNewt re-links the loader to ensure all of these symbols are present in the loader application (by forcing the linker to include them in the \n.elf\n). \n\n\nNewt builds a special copy of the loader.elf with only these symbols (and the handful of symbols discussed in the linking section above).\n\n\nFinally, newt links the application, replacing the common .a libraries with the special loader.elf image d
uring the link. \n\n\nDesign\n\n\nBootloader\n\n\nThe bootloader has been modified to support \"non bootable\" images like split app images. A flag in the image header denotes the image as \"non-bootable\". When this flag is set, the bootloader will not boot the split app image, nor will it copy it to the slot 1 location. Loader images are bootable, split app images are not.\n\n\nNewt\n\n\nNewt builds a split image when the token \nloader=@apache-mynewt-core/apps/slinky\n is present in the target file.\n\n\nNewt has a \nBuilder\n object that is responsible for building an image. This features a \ntargetBuilder\n object that contains two builders (one for the app and one for the loader).\n\n\nThe \nBuilder\n object has been expanded to include options for building as part of a split image.\n\n Ability to specify the linker file during the link\n\n Ability to specify a set of keep_symbols during the link\n\n\nNewt commands like download, size, create-image have been expanded to perf
orm operations twice (once for loader and once for app) if the loader target is present.\n\n\nDuring normal single-image builds, the \ntargetBuilder\n initializes and builds the application \nbuilder\n. During the split image build, the \ntargetBuilder\n performs the steps outlined in the section above using the two \nbuilder\ns for the loader and app.\n\n\nSpecial symbol and link features are designed as follows:\n\n\n\n\nNewt uses objdump to parse the symbol maps in the \n.a\n and \n.elf\n files. \n\n\nNewt uses the \n--undefined=\n option of the linker to force the loader to keep symbols used by the app (but not used by the linker)\n\n\nNewt uses objcopy with the \n-K\n (keep) option when building the special linker \n.elf\n.\n\n\nNewt uses the \n--just-symbols\n option of the linker to link against the loader \n.elf\n file. \n\n\n\n\nnewt create-image\n\n\nCreate image uses two different methods to compute the image hash for standard and split images. For split images, the has
h is computed starting with the 32-byte hash of the loader, then continuing with the hashing algorithm used by the standard application. This ensures that the split app can be \"validated\" against a loader image specifically. \n\n\nnewt errors\n\n\nNewt has several new build errors when building split images. \n\n\n\n\nLinker script undefined. If the BSP for your application does not define a split image linker script the build will fail.\n\n\n\n\nIf newt finds that the same library (for example libs/os) has a different implementaiton in the loader and app, it will generate an error and fail to build. These differences can arise when \n#ifdef\n or features are included in one app and not the other. For example, it the loader includes \nlibs/console/stubs\n and the app includes \nlibs/console/full\n this may change implementations of certain functions within other packages. \n\n\nImage manifest\n\n\nnewt builds a single manifest for split images, adding extra tags to the mani

See newtmgr below for details.\n\n\nIt also contains the function used by a loader to validate and boot a split image. \n\n\napps/slinky\n\n\nA sample app that can be built as a split image with slinky.\n\n\nTips when Building Split images\n\n\nTo b
e added\n\n\nAdding BSP support for split images\n\n\nA BSP needs additional components to be \"split image ready\".\n\n\nThe split image requires a special linker script. The split image needs to run from the second image partition (since it's using the loader library that is linked to be placed in the first partition). It needs to reserve space for RAM used by the loader. It also does not need to include the vector table (just a bit of it).\n\n\nThe startup of the split image is different than a typical image. It needs to copy \n.data\n from the loader image, and zero the loader image bss. For this, it must reference symbols defined in the linker script of the loader. It has a special entry symbol that differentiates it from the entry symbol in the loader application. \n\n\nSeveral of the bsp scripts need to handle additional agruments to deal with the two images produced by newt when building split images - mainly download and debug.\n\n\nAdd the following components to enab
le your BSP for split images:\n\n\n\n\nA split image linker file\n\n\nA startup file for the split image\n\n\nA property in the pkg.yml file to tell newt what linker script to use for partition 2 images. The property is defined as \npkg.part2linkerscript: \"split-nrf52dk.ld\n for example.\n\n\nModified download script\n\n\n\n\nAn example can be found in the \n/hw/bsp/nrf52dk\n\n\nsplit image linker script\n\n\nThe split image linker script must have the following.\n\n\nThe split linker must define the entry symbol as Reset_Handler_split. For example:\n\n\nENTRY(Reset_Handler_split)\n\n\n\n\n\nThe split linker must define the first two words in the vector table (initial SP and Reset Vector). The additional vector entries are part of the loader. The bootloader accesses these entries at the beginning of the image slot (first 2 words). For example:\n\n\n .text :\n {\n __split_isr_vector_start = .;\n KEEP(*(.isr_vector_split))\n __split_isr_vector_end = .;\n
... \n\n\n\n\n\nThe split linker must ensure that it doesn't overwrite the BSS and DATA sections of the loader (they are both using RAM). Note, the two apps don't run at the same time, but the loader has global data that its libraries use. This cannot be overwritten by the application. An example linker section that accomplishes this can be found in \n/hw/bsp/nrf52dk/split-nrf52dk.ld\n. When linking against the loader, the loader exports the following symbosl which can be used by the split app code:\n\n\n\n\n__HeapBase_loader\n\n\n__bss_start___loader\n\n\n__bss_end___loader\n\n\n__etext_loader\n\n\n__data_start___loader\n\n\n__data_end___loader\n\n\n\n\nThe split app linker can use \n__HeapBase_loader\n to skip RAM used by the loader as follows.\n\n\n /* save RAM used by the split image. This assumes that \n * the loader uses all the RAM up to its HeapBase */\n .loader_ram_contents :\n {\n _loader_ram_start = .;\n\n /* this symbol comes from th
e loader linker */\n . = . + (ABSOLUTE(__HeapBase_loader) - _loader_ram_start);\n _loader_ram_end = .;\n } \n RAM\n\n\n\n\n\nsplit image startup code\n\n\nThe split application needs separate startup code to intialize the split image before running main. THe split image is specially linked so that _start and main are included individually for the loader and split app.\n\n\nThe split app startup code must have the following.\n\n\n\n\nA definition of the split image vector table (first two words). \n\n\nThe entry point function to start the code \nReset_Handler_split\n\n\nCode that copies the .data section for the loader from Flash to RAM\n\n\nCode that zeros the .bss section for the loader.\n\n\nCode that calls _sbrkInit to set the heap pointers for the application\n\n\n\n\nAn example can be found in the \n/hw/bsp/nrf52dk/src/arch/cortex_m4/gcc_startup_nrf52_split.s\n\n\nnewtmgr and split Images\n\n\nnewtmgr has support for split images.\n\n\nnewtmgr image list2\n lists
the current images in the flash. Its clear from the output that some images are non-bootable. For example.\n\n\nImages:\n slot=1\n version=1.2.3\n bootable=true\n hash=55e254f133bedf640fc7be7b5bfe3e5fb387cf5e29ecd0d4ea02b5ba617e27e0\n slot=2\n version=1.2.3\n bootable=false\n hash=1697bd1658f7e902e0191094c5f729446c9dd790c00a58e2bb37f56d6fcb72fe\n\n\n\n\n\nThe bootloader is unable to boot split app images (of course it can boot the loader images), so do not use the \nboot2\n command to instruct mynewt to boot slot 2. \n\n\nInstead, use the new \nsplit status\n command to see the status of split images and to set their boot status. The split status command with no arguments returns status of the split image. The Split Value tells the loader how to boot the split app. Options are:\n\n\n\n\nnone\n Don't boot the split application. Just remain running in the loader.\n\n\ntest\n Boot the split application, but revert back to the loader on the next reset.\n\n\nrun\n
Boot the split application.\n\n\n\n\nThe split status command also verified the hash of the split application (using the hash of the loader as shown above) and returns the status of the check (matching or non-matching).\n\n\nnewtmgr -c connection split status \n Split value is none\n Split status is matching\n\n\n\n\n\nWhen the split image application is running, the active hash in the boot2 command will match the hash of the split application (in slot 2). For example:\n\n\nprompt$ newtmgr -c foo1 image boot2\n Test image: 55e254f133bedf640fc7be7b5bfe3e5fb387cf5e29ecd0d4ea02b5ba617e27e0\n Main image: 55e254f133bedf640fc7be7b5bfe3e5fb387cf5e29ecd0d4ea02b5ba617e27e0\n Active img: 1697bd1658f7e902e0191094c5f729446c9dd790c00a58e2bb37f56d6fcb72fe\n\n\n\n\n\nUpgrading a split image with newtmgr\n\n\nWhen running via newt, the \nnewt load\n command will load both parts of a split image, the loader and application.\n\n\nWhen running via newtmgr a sequence of commands is required to
upgrade. Assuming you are running the split app in \nrun\n mode the following sequence will upgrade\n\n\n\n\nnewtmgr split status none\n\n\nnewtmgr reboot\n\n\nnewtmgr image upload \n\n\nnewtmgr image boot2 \n\n\nnewtmgr reboot\n\n\nnewtmgr image upload \n\n\nnewtmgr split status test\n\n\nnewtmgr reboot\n\n\nnewtmgr boot2 (check status to ensure new app is running)\n\n\nnewtmgr split status run\n\n\n\n\nThis upgrade is robust. In all steps there is a loader image that is capable of upgrading (or reverting) images.",
