    Below that the " Next steps - further reading " section provides a set of links to enable you to further your knowledge, answer common questions, and become an expert FreeRTOS user. Each RTOS port is accompanied by a pre-configured demo application to get you up and running quickly. Better still, each demo application is accompanied by a documentation page providing full information on locating the RTOS demo project source code, building the demo project, and configuring the target hardware. The demo application documentation page also provided essential RTOS port specific information, including how to write FreeRTOS compatible interrupt service routines, which is necessarily slightly different on different microcontroller architectures. To get up an running in minutes - follow these easy instructions: Port documentation pages are grouped by device manufacturer. Expand the list of supported devices, then click the manufacturer of interest to be taken to a list of demo documentation pages. This contains the RTOS kernel source code and demo projects for every official port. Don't be overwhelmed by the amount of files, only a tiny subset are required for one demo! Unzip the files into a convenient directory. Clicking a microcontroller vendor name will take you to a list of documentation pages specific to that vendor. Refer to the Modifying a demo application to run on different hardware page should a pre-configured port not be available for your development board.

    The reaction time of the slave core depends on the technical realisation of the synchronization. If no specific configuration is performed, the synchronization is done by software eg: On the other side, if the on-chip Cross Trigger Interface is configured, the synchronization takes place directly on the processor.

    This is a faster solution and the time delay between reaction of different cores becomes around ns. The CTI interface for chip Zynq is configured with the following commands. The symbolic information is useful for HLL debugging, or setting breakpoints, stepping through the code, viewing variables, and many other aspects of debugging. The compiler must be configured in order to generate debug symbols.

    The vmlinux file for the running kernel must be available, in order to load the kernel debug symbols.

    No instrumentation is needed in the kernel source code for debugging with Lauterbach, but it's important that the vmlinux file is generated from the same kernel build as the zImage or uImage running on the system. The Data. LOAD command is used to load the kernel symbols, and the sYmbol. SourcePATH command can be used, if necessary, to define additional search directories for the source files.

    Specific options must be configured to avoid automatic Break of TRACE32 debugger, in case any of the following events happens due to normal Linux operations. For more details, please refer to:.

    Debug is significantly simplified, as the user can immediately access all the components of the OS and the application.

    The Linux kernel awareness is configured with the commands:. The Linux menu file linux.

    The kernel awareness supports Linux MMU format and is able to handle virtual memory addressing. List KernelPageTable , executed when the kernel is up and running. COMMON , the virtual address range has been extended below the kernel start address, because kernel objects are loaded in this memory range.

    The Linux kernel can be compiled to allow linking of additional modules at runtime kernel objects. The Lauterbach debuggers also support kernel modules debugging, starting from the initialization function. User process debugging is also available, starting from the very beginning of the process.

    If the process loads shared objects, they are loaded in the process address space when the related instructions are executed for the first time demand paging. The Lauterbach debuggers also support debug of threads for multithreaded processes.

    In this case, the same address space is shared between different threads and the symbolic information can be loaded only once per process. In general, the same techniques used for debugging kernel code, such as setting breakpoints, stepping through code, watching variables, and viewing memory contents, can be performed in the same way for processes and tasks.

    The memory addressing is extended using the lower 16 bit of the process PID, allowing in this way to distinguish between equal virtual addresses for different processes. The ETB stores program-flow trace information on-chip at high rates and at bit data width.

    The data can be read out via JTAG, when the trace recording has ended. Configuration allows a full control of configuration, initialization and listing of trace information.

    In this way, an easy comparison is possible of program flow of each core at the same time. The following is the U-Boot environment that can be printed using the print command please note these are examples and that the actual variables may differ for different U-Boot settings , for both the FreeRTOS applications described in this application note.
