Author: Ming Yue <mingyue86010@gmail.com> Date: Tue Aug 11 17:06:59 2020 -0700 Remove unused wolfSSL files. (#197) * Remove unused wolfSSL files. * Add back some removed ciphers. * Update VS project file. commit 0e0edd96e8236b2ea4a6e6018812807be828c77f Author: RichardBarry <3073890+RichardBarry@users.noreply.github.com> Date: Tue Aug 11 10:50:30 2020 -0700 Use new QEMU test project to improve stream/message buffer tests (#168) * Add Eclipse/GCC project that targets the LM3S8962 QEMU model. * Get the Cortex-M QEMU project working. * Continue working on making stream buffer demo more robust and QEMU project. * Rename directory CORTEX_LM3S8986_QEMU to CORTEX_LM3S6965_QEMU. Work on making the Stream Buffer tests more robust. Check in before adding in the trace recorder. * Rename CORTEX_LM3S6969_QEMU to CORTEX_LM3S6969_GCC_QEMU. * Make the StreamBufferDemo.c common demo file (test file) more robust to other test tasks running at an equally high priority. * Work in progress checkin only - comments in main.c are incorrect. * Correct comments at the top of FreeRTOS/Demo/CORTEX_LM3S6965_GCC_QEMU/main.c Make the message buffer tests more robust in the case the a message buffer becomes full when prvSenderTask() has a higher priority than the reader task. * Disable trace recorder in the LM3S6965 QEMU demo. * I'm dropping FreeRTOS-Kernel reference update, since this seems to break the CMBC CI.

Next TaskNotifyArray.c will be refactored to break the tests up a bit. * Refactor and update the comments in TaskNotifyArray.c - no functional changes. * Change from the task notify "array" to task notification "indexed" nomenclature in the new task notification API functions that work on one particular task notification with the array of task notifications. * Update the implementation of the taskNOTIFY_TAKE() and taskNOTIFY_WAIT() trace macros to take the array index of the task notification they are acting on. Rename configNUMBER_OF_TASK_NOTIFICATIONS to configTASK_NOTIFICATION_ARRAY_ENTRIES. Add FreeRTOS/Demo/Common/Minimal/TaskNotifyArray.c to the Visual Studio project - the file implements tests specific to the behaviour of the indexed task notification functions and should be used in addition to the tests already provided in FreeRTOS/Demo/Common/Minimal/TaskNotify.c. commit b9e4ecfaf7286d8493d4a96a93fbb325534ad97b Author: Aniruddha Kanhere <60444055+AniruddhaKanhere@users.noreply.github.com> Date: Fri Jun 5 11:10:58 2020 -0700 Remove Empty and Un-referenced folder from Demo (#86) commit f11bcc8acc57a23fb03603762e758c25b9d0efb7 Author: Aniruddha Kanhere <60444055+AniruddhaKanhere@users.noreply.github.com> Date: Wed Jun 3 16:52:31 2020 -0700 Fix a Bug and corresponding CBMC patch (#84) * Update remove-static-in-freertos-tcp-ip.patch * Update FreeRTOS_TCP_IP.c * Update remove-static-in-freertos-tcp-ip.patch * Update remove-static-in-freertos-tcp-ip.patch Co-authored-by: Yuhui Zheng <10982575+yuhui-zheng@users.noreply.github.com> commit bb9f92f771e5f6ea2b9b09c7e89130a75e562eb7 Author: Yuhui Zheng <10982575+yuhui-zheng@users.noreply.github.com> Date: Wed Jun 3 10:46:55 2020 -0700 Submodule FreeRTOS/Source 10bbbcf0b..6199b72fb (#82) commit 6efc39f44be5b269168836e95aebbdb8ae77dce3 Author: Aniruddha Kanhere <60444055+AniruddhaKanhere@users.noreply.github.com> Date: Tue Jun 2 15:09:25 2020 -0700 Add Project for running integration tests v2 (#80) * Project for integration tests * relative paths in project files * relative paths in project files-1 * relative paths in project files-2 * addressed comments * addressed comments v2 Co-authored-by: Yuhui Zheng <10982575+yuhui-zheng@users.noreply.github.com> commit 0eb5909fb02bac9dc074ff1bc2fe338d77f73764 Author: Yuhui Zheng <10982575+yuhui-zheng@users.noreply.github.com> Date: Thu May 28 17:05:24 2020 -0700 readme.md for ATmega328PB Xplained Mini.

SCons (https://scons.org/) is used as the build system. This will be built as a 64-bit application, but note that the memory allocation trace points only record the lower 32-bits of the address. commit f78f919b3e2f0d707531a301a8ca07cd02bc4778 Author: Markus Rinne <markus.ka.rinne@gmail.com> Date: Thu Mar 19 21:00:24 2020 +0200 Fix function comments commit 1cd2d38d960a3576addb224582c88489bade5141 Author: David Chalco <david@chalco.io> Date: Fri Mar 20 10:29:05 2020 -0700 unix separators for path and remove .exe suffix from risc compiler (works on windows/mac) commit 938b19419eded12817737ab0644e94ed2ba7e95d Author: Yuhui Zheng <10982575+yuhui-zheng@users.noreply.github.com> Date: Thu Mar 19 18:23:09 2020 -0700 Removing ./FreeRTOS-Labs directory, since: - IoT libraries are now in LTS branch. - FAT/POSIX/Light-weight MQTT are in https://github.com/FreeRTOS/FreeRTOS-Labs. commit 1a4abbc9e91b13fd6394464ade59d5e048320c7c Author: Yuhui Zheng <10982575+yuhui-zheng@users.noreply.github.com> Date: Tue Mar 17 19:30:02 2020 -0700 Maintenance -- clean up readme.txt and add url to GitHub.

When releasing, please follow these steps: 1. in local directory, clean directory and check "git status" shows "nothing to commit, working tree clean" for ALL subdirectories. 2. copy source code and instructions only to an empty folder. Git related should not be in this folder -- this covers .git, .gitignore, .github, .gitmodules, gitmessages, ...... 3. zip the folder from step 2. (create both .zip and .7z) 4. attach .zip and .7z to the release. (e.g. attach these two in new release -- https://github.com/FreeRTOS/FreeRTOS/releases/new) 5. PLEASE download both, unzip, diff with your local git repo. (should not see any difference other than git related.)

+ *
+ * The Queue Send Task:
+ * The queue send task is implemented by the prvQueueSendTask() function in
+ * this file.  prvQueueSendTask() sits in a loop that causes it to repeatedly
+ * block for 200 milliseconds, before sending the value 100 to the queue that
+ * was created within main_blinky().  Once the value is sent, the task loops
+ * back around to block for another 200 milliseconds...and so on.
+ *
+ * The Queue Receive Task:
+ * The queue receive task is implemented by the prvQueueReceiveTask() function
+ * in this file.  prvQueueReceiveTask() sits in a loop where it repeatedly
+ * blocks on attempts to read data from the queue that was created within
+ * main_blinky().  When data is received, the task checks the value of the
+ * data, and if the value equals the expected 100, toggles an LED.  The 'block
+ * time' parameter passed to the queue receive function specifies that the
+ * task should be held in the Blocked state indefinitely to wait for data to
+ * be available on the queue.  The queue receive task will only leave the
+ * Blocked state when the queue send task writes to the queue.  As the queue
+ * send task writes to the queue every 200 milliseconds, the queue receive
+ * task leaves the Blocked state every 200 milliseconds, and therefore toggles
+ * the LED every 200 milliseconds.

+# Overview
+
+This directory contains a MPLAB-X demo project (XC8 compiler) for AVR128DA48 Curiosity Nano board equipped with AVR128DA48 microcontroller (128 KB Flash, 16 KB SRAM, 512 bytes EEPROM).  
+
+The project comes as three different demos, selectable by a define in the main.c file. Each demo has its own main-***demo_name***.c file. Follow the instructions on the RTOS port documentation page for details about how to setup the target hardware, download and execute the demo application.
+
+### Blinky Demo
+
+**#define       mainSELECTED_APPLICATION	  0**
+
+Blinky demos are intended for beginners. They normally create just two [tasks](https://www.freertos.org/a00015.html) that communicates with each other through a [queue](https://www.freertos.org/Embedded-RTOS-Queues.html). Their functionality is contained in a single C source file called **main_blinky.c**.
+
+One of the tasks repeatedly sends a predefined value to the queue with 200 ms intervals, while the other task waits for messages to be available in the queue. Once a new message is available, it toggles on board LED if the value matches the expected value.
+
+
+### Minimal Demo
+
+**#define       mainSELECTED_APPLICATION	  1**
+
+This demo includes a higher number of tasks than the **Blinky demo**, but the complexity is still fairly low. Whole functionality is included in the **main_minimal.c** file by using the following tasks:
+
+ - integer math task (**Integer.c**)
+ - register tasks to verify the context switch (**Regtest.c**)
+ - polled queue tasks (**PollQ.c**)
+ - serial communiation tasks (**Serial.c**)
+ - check task that periodically checks the other tasks are operating without error.
+
+This demo uses the **check** task to periodically inspect the standard demo tasks in order to ensure all the tasks are functioning as expected. The check task also toggles an LED to give a visual feedback of the system status. If the LED is toggling roughly every second, then the check task has not discovered any problems. If the LED stops toggling, then the check task has discovered a problem in one or more tasks.
+
+To see the console output from serial communication tasks, serial port could be configured as: 
+ - baud rate 9600
+ - data 8-bit
+ - parity none
+ - stop bits 1-bit
+ - flow control none
+
+### Full Demo
+
+**#define       mainSELECTED_APPLICATION	  2**
+
+This demo is a comprehensive demonstration and test of a lot of FreeRTOS features, including direct task to task notifications, queues, semaphores, recursive semaphores, software timers, and more. The following tasks are created in **main_full.c** file:
+
+ - register tasks to verify the context switch (**Regtest.c**)
+ - semaphores task (**Semtest.c**)
+ - direct task to task notification task (**TaskNotify.c**)
+ - recursive semaphores task (**Regmutex.c**)
+ - check task that periodically checks the other tasks are operating without error
+
+The demo uses the **check** task to periodically inspect the standard demo tasks in order to ensure all the tasks are functioning as expected. The check task also toggles an LED to give a visual feedback of the system status. If the LED is toggling roughly every 3 seconds, then the check task has not discovered any problems. If the LED stops toggling, then the check task has discovered a problem in one or more tasks.
+
+# Quick start
+
+To run this demo on AVR128DA48 Curiosity Nano platform, the following steps are required:
+ - install **MPLAB® X IDE**
+ - install **MPLAB® XC8** compiler
+ - open **AVR_ATMega4809_MPLAB.X** project file from current folder
+ - select desired demo using **#define       mainSELECTED_APPLICATION** as explained in the previous section
+ - build and debug the project
