PSDK RTOS: PDK OVERVIEW PLATFORM DEVELOPMENT KIT (PDK) PROVIDES Low Level software device drivers (LLD), Chip support software (CSL) LLD and CSL configure and manage HW, and provide I/O capabilities OS Abstraction layer (OSAL) Board library DEVICE DRIVERS Device Drivers maintain common APIs for all supported SoCs Scalability advantage: Customer applications can be easily ported to another supported SoCs. STARTERWARE is included in PSDK-RTOS AM335x and AM437x for backwards compatibility with ISDK 2.1 This will be maintenance only (bugs will be fixed, no new features) FOR APPLICATIONS that already depend on StarterWare from Industrial SDK 2.1 on AM335x/AM437x, those APIs remain in Processor SDK in: AM335x SoC: pdk_am335x_1_0_x/ti/starterware AM437x SoC: pdk_am437x_1_0_x/ti/starterware
PDK COMPONENTS: CHIP SUPPORT LIBRARY (CSL) CSL constitutes a set of well-defined APIs that abstract low-level details of the underlying SoC device. Users can configure, control (start/stop, etc.) and have read/write access to peripherals without having to worry about register bit-field details. CSL Implements distinctive modules, which correspond with underlying SoC device modules. CSL APIs follow consistent style and uniformity across processors. Increase portability. API s for each module are orthogonal One module s API doesn t internally call an API from another module. For more information see - http://processors.wiki.ti.com/index.php/processor_sdk_rtos_csl
PDK COMPONENTS: CHIP SUPPORT LIBRARY (CSL) OVERVIEW (Almost) All peripherals are controlled by Memory Mapped Registers (MMR). The CSL has two layers: The first layer assigns a standard name to MMR. Uses macros and type definitions. The second layer is a set of C functions to manipulate these registers. The application or LLD needs only to know the API of the CSL functions in order to access the HW registers.
PDK COMPONENTS: LLD AND CSL Low Level Drivers (LLD) hide the details of CSL from the application. In general apps are recommended to use the Driver APIs. However, some IP and peripherals do not have LLD. In those cases application can use CSL Functional layer directly. Also, some LLD can access the hardware directly (and not via CSL).
PDK COMPONENTS: LOW LEVEL DRIVERS (LLD) OVERVIEW LLDs are hardware drivers that talk directly, or via CSL, to the hardware registers. LLDs are used to hide (abstract) hardware implementation, or CSL, details from the user. Most peripheral and SoC specific configuration is done using the LLDs. Most of LLD code and pre-build libraries are located in the PDK directory. For more information visit Device Drivers sections: http://processors.wiki.ti.com/index.php/processor_sdk_rtos_software_developer_guide
PDK COMPONENTS: LOW LEVEL DRIVERS (LLD) PDK AM57x device drivers pdk_am57xx_<version>\packages\ti\drv PDK AM335x-AM437x device drivers pdk_<device>_<version>\packages\ti\drv
PDK COMPONENTS: OS ABSTRACTION LAYER (OSAL) pdk_<device>_<version>\packages\ti\osal OSAL provides the wrappers, and APIs for encapsulating OS functions Makes drivers OS independent OSAL is a starting point for projects that use a different OS. Examples of OSAL s utilities are: Interrupt Handling Semaphore Handling
PDK COMPONENTS: BOARD LIBRARY pdk_<device>_<version>\packages\ti\board The Board Library is a thin utility layer on top of CSL Provides uniform configuration APIs for all supported boards (EVMs). Hides the HW details of the board to the drivers. This helps users to write portable applications for all the supported EVMs The board library provides a high level abstraction for configuring: PinMux, Device Clock tree, DDR features, PLL, Memory Map, Board specific components like PMIC, PHY, Flash, IO expanders, etc.
PDK COMPONENTS: SECONDARY BOOTLOADER (SBL) ROM BOOTLOADER (RBL) FUNCTIONS: RBL is the first SW to run on SoC on Power-on-reset RBL read SYSBOOT pins and choose booting device If not valid booting device, RBL checks for the next device. If a valid bootloader is found then, RBL configures and initialize the boot media Ex: Clocks and peripherals for the booting device (MPU, I2C, MMCSD, USB, SPI, QSPI, Ethernet etc). RBL gets SBL image size and load address by checking TI image header appended on bootloader binary (.bin). Loads SBL image to internal memory, at the address fetched from TI image header. Passes control to Secondary Bootloader(SBL) Wiki documentation: http://processors.wiki.ti.com/index.php/processor_sdk_rtos_boot_am335x/am437x
PDK COMPONENTS: SECONDARY BOOTLOADER (SBL) SBL FUNCTIONS: Sets up SoC: PLL clock, PinMux, PRCM. Powers on the I/O Peripherals, initializes the DDR. Read multi-core image from boot media. Loads the application image from memory device into DDR (typically). Wakes up secondary cores from reset. Populates boot addresses. Passes control to application. Cores start executing their associated code. Wiki documentation: http://processors.wiki.ti.com/index.php/processor_sdk_rtos_boot_am335x/am437x
PDK COMPONENTS: SECONDARY BOOT LOADER (SBL) <pdk_am57xx>_<version>\packages\ti\boot\sbl SBL includes tools and utilities to support multi-core deployment of applications from boot. It also provides SoC-dependent functions To initialize the SoC To perform slave core boot-up. For single core devices (AM335x and AM437x), SBL is not necessary as they can boot directly from ROM However SBL gives additional flexibility to enable features that are not supported in RBL. Pre-built version of the SBL is provided in the PSDK The PSDK demos and diagnostics application use SBL booting scheme to load and run applications from an SD card on non-volatile memory on the boards.

Inter-processor communication Framework Components. Modifying the board library is the major step required while porting the software to the custom platform. Non-OS Software Aside from the Board library - the SBL and diagnostics components may need to be modified. Application level changes are limited as all of the high level drivers and application relies on this board library for hardware configuration. Components that may require modification Components that will require modification
Custom HW: May or may not be based on TI s EVM Board library will need to reflect custom board changes. MIGRATION TO CUSTOM BOARD: FUNCTIONAL VIEW Components that may need modification* *Depend if peripheral instant from custom board matches or not TI EVM Components that will definitely need modification.
The Board diagnostics is a sample test code to validate the hardware, for manufacturing and component defects MIGRATION TO CUSTOM BOARD: FUNCTIONAL VIEW Can be loaded and executed over emulator (JTAG), or run directly from an SD card in system boot Diagnostics uses LLDs and board library so it may require some modification based on custom board changes. Components that may need modification* *Depend if peripheral instant from custom board matches or not TI EVM Components that will definitely need modification.
App build on top of the CSL and LLD and also depend on the board library to initialize and configure the hardware. MIGRATION TO CUSTOM BOARD: FUNCTIONAL VIEW May require changes, for example if custom board uses a different instance of a peripheral, or if the application requires a peripheral mode that is not supported on the TI s EVM. Components that may need modification* *Depend if peripheral instant from custom board matches or not TI EVM Components that will definitely need modification.
MIGRATION TO CUSTOM BOARD: FUNCTIONAL VIEW LLD relies on the board library to provide board specific initialization and configurations and will remain unchanged while moving to the custom platform. OSAL remains unchanged in the software migration process. CSL remains unchanged on custom platform as both TI EVM and custom platforms use the same SoC. Components that may need modification* *Depend if peripheral instant from custom board matches or not TI EVM Components that will definitely need modification.
MIGRATION TO CUSTOM BOARD: FUNCTIONAL VIEW SBL uses board library for initializing clocks and peripherals (which are not init by RBL). And relies on pre-defined Memory Map of the device memory. Also depends on chosen device media for booting (typically flash). Then, some changes might be needed in SBL for a new custom board. Components that may need modification* *Depend if peripheral instant from custom board matches or not TI EVM Components that will definitely need modification.

02 PRU-ICSS INDUSTRIAL SW PROTOCOLS PRU ICSS INDUSTRIAL PROTOCOLS ADVANTAGES Industrial package has been modularized Each industrial protocol has a separate add-on package that can be used with PSDK-RTOS. Easier migration to custom platforms because platform changes are consolidated in board software. Incremental software changes, when moving to newer TI platforms like AM57xx and K2G. Improved maintenance of existing protocols. For any Industrial protocol, a release with a bug fixed, or a new feature can be updated easier instead of pushing a release for the whole ISDK. One device enables multiple protocols: Profibus, Profinet, Sercos, Ethernet/IP, POWERLINK, EtherCAT, and more. Supports Master and Slave. Simplifies the addition of new protocols. TI industrial communications solutions are tested, certified, and supported. Available as free download: PRU-ICSS-INDUSTRIAL-SW
