## Full Demo
|
||||||
|
### How to build blinky demo
|
||||||
|
Navigate with the command line to FreeRTOS/Demo/CORTEX\_M3\_MPS2\_QEMU\_GCC
|
||||||
|
For a release build run:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ export PATH=/path/to/arm/toolchain:$PATH
|
||||||
|
$ make FULL_DEMO=1
|
||||||
|
```
|
||||||
|
For a versions with debugging symbols and no optimizations **-O0**, run:
|
||||||
|
```
|
||||||
|
$ make FULL_DEMO=1 DEBUG=1
|
||||||
|
```
|
||||||
|
|
||||||
|
### How to run the Full Demo
|
||||||
|
run:
|
||||||
|
```
|
||||||
|
$ sudo qemu-system-arm -machine mps2-an385 -monitor null -semihosting \
|
||||||
|
--semihosting-config enable=on,target=native \
|
||||||
|
-kernel ./build/RTOSDemo.axf \
|
||||||
|
-serial stdio -nographic
|
||||||
|
```
|
||||||
|
### Full Demo Expectations
|
||||||
|
The full demo includes a ‘check’ that executes every (simulated) ten seconds,
|
||||||
|
but has the highest priority to ensure it gets processing time. Its main
|
||||||
|
function is to check all the standard demo tasks are still operational. The
|
||||||
|
check task maintains a status string that is output to the console each time
|
||||||
|
it executes. If all the standard demo tasks are running without error, then
|
||||||
|
the string contains “OK” and the current tick count. If an error has been
|
||||||
|
detected, then the string contains a message that indicates which task
|
||||||
|
reported the error.

* NOTE 1: The POSIX port is a simulation (or is that emulation?) only! Do not
|
||||||
|
* expect to get real time behaviour from the POSIX port or this demo
|
||||||
|
* application. It is provided as a convenient development and demonstration
|
||||||
|
* test bed only.
|
||||||
|
*
|
||||||
|
* Linux will not be running the FreeRTOS simulator threads continuously, so
|
||||||
|
* the timing information in the FreeRTOS+Trace logs have no meaningful units.
|
||||||
|
* See the documentation page for the Linux simulator for an explanation of
|
||||||
|
* the slow timing:
|
||||||
|
* https://freertos-wordpress.corp.amazon.com/FreeRTOS-simulator-for-Linux.html
|
||||||
|
* - READ THE WEB DOCUMENTATION FOR THIS PORT FOR MORE INFORMATION ON USING IT -
|
||||||
|
*
|
||||||
|
* NOTE 2: This project provides two demo applications. A simple blinky style
|
||||||
|
* project, and a more comprehensive test and demo application. The
|
||||||
|
* mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select
|
||||||
|
* between the two. See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY
|
||||||
|
* in main.c. This file implements the comprehensive test and demo version.
|
||||||
|
*
|
||||||
|
* NOTE 3: This file only contains the source code that is specific to the
|
||||||
|
* full demo. Generic functions, such FreeRTOS hook functions, are defined in
|
||||||
|
* main.c.
|
||||||
|
*******************************************************************************
|
||||||
|
*
|
||||||
|
* main() creates all the demo application tasks, then starts the scheduler.
|
||||||
|
* The web documentation provides more details of the standard demo application
|
||||||
|
* tasks, which provide no particular functionality but do provide a good
|
||||||
|
* example of how to use the FreeRTOS API.
|
||||||
|
*
|
||||||
|
* In addition to the standard demo tasks, the following tasks and tests are
|
||||||
|
* defined and/or created within this file:
|
||||||
|
*
|
||||||
|
* "Check" task - This only executes every five seconds but has a high priority
|
||||||
|
* to ensure it gets processor time. Its main function is to check that all the
|
||||||
|
* standard demo tasks are still operational. While no errors have been
|
||||||
|
* discovered the check task will print out "OK" and the current simulated tick
|
||||||
|
* time. If an error is discovered in the execution of a task then the check
|
||||||
|
* task will print out an appropriate error message.
