/001_FreeRTOS_LEDtask/FreeRTOS/portable/RVDS/ARM_CM7/ReadMe.txt:
--------------------------------------------------------------------------------
1 | There are two options for running FreeRTOS on ARM Cortex-M7 microcontrollers.
2 | The best option depends on the revision of the ARM Cortex-M7 core in use. The
3 | revision is specified by an 'r' number, and a 'p' number, so will look something
4 | like 'r0p1'. Check the documentation for the microcontroller in use to find the
5 | revision of the Cortex-M7 core used in that microcontroller. If in doubt, use
6 | the FreeRTOS port provided specifically for r0p1 revisions, as that can be used
7 | with all core revisions.
8 |
9 | The first option is to use the ARM Cortex-M4F port, and the second option is to
10 | use the Cortex-M7 r0p1 port - the latter containing a minor errata workaround.
11 |
12 | If the revision of the ARM Cortex-M7 core is not r0p1 then either option can be
13 | used, but it is recommended to use the FreeRTOS ARM Cortex-M4F port located in
14 | the /FreeRTOS/Source/portable/RVDS/ARM_CM4F directory.
15 |
16 | If the revision of the ARM Cortex-M7 core is r0p1 then use the FreeRTOS ARM
17 | Cortex-M7 r0p1 port located in the /FreeRTOS/Source/portable/RVDS/ARM_CM7/r0p1
18 | directory.
--------------------------------------------------------------------------------
/001_FreeRTOS_LEDtask/FreeRTOS/portable/readme.txt:
--------------------------------------------------------------------------------
1 | Each real time kernel port consists of three files that contain the core kernel
2 | components and are common to every port, and one or more files that are
3 | specific to a particular microcontroller and/or compiler.
4 |
5 |
6 | + The FreeRTOS/Source/Portable/MemMang directory contains the five sample
7 | memory allocators as described on the http://www.FreeRTOS.org WEB site.
8 |
9 | + The other directories each contain files specific to a particular
10 | microcontroller or compiler, where the directory name denotes the compiler
11 | specific files the directory contains.
12 |
13 |
14 |
15 | For example, if you are interested in the [compiler] port for the [architecture]
16 | microcontroller, then the port specific files are contained in
17 | FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the
18 | only port you are interested in then all the other directories can be
19 | ignored.

1 | Each real time kernel port consists of three files that contain the core kernel
2 | components and are common to every port, and one or more files that are
3 | specific to a particular microcontroller and or compiler.
4 |
5 | + The FreeRTOS/Source directory contains the three files that are common to
6 | every port - list.c, queue.c and tasks.c. The kernel is contained within these
7 | three files. croutine.c implements the optional co-routine functionality - which
8 | is normally only used on very memory limited systems.
9 |
10 | + The FreeRTOS/Source/Portable directory contains the files that are specific to
11 | a particular microcontroller and or compiler.
12 |
13 | + The FreeRTOS/Source/include directory contains the real time kernel header
14 | files.

16 | See the readme file in the FreeRTOS/Source/Portable directory for more

/Template_FreeRTOS/FreeRTOS/portable/RVDS/ARM_CM7/ReadMe.txt:
--------------------------------------------------------------------------------
1 | There are two options for running FreeRTOS on ARM Cortex-M7 microcontrollers.
2 | The best option depends on the revision of the ARM Cortex-M7 core in use. The
3 | revision is specified by an 'r' number, and a 'p' number, so will look something
4 | like 'r0p1'. Check the documentation for the microcontroller in use to find the
5 | revision of the Cortex-M7 core used in that microcontroller. If in doubt, use
6 | the FreeRTOS port provided specifically for r0p1 revisions, as that can be used
7 | with all core revisions.
8 |
9 | The first option is to use the ARM Cortex-M4F port, and the second option is to
10 | use the Cortex-M7 r0p1 port - the latter containing a minor errata workaround.
11 |
12 | If the revision of the ARM Cortex-M7 core is not r0p1 then either option can be
13 | used, but it is recommended to use the FreeRTOS ARM Cortex-M4F port located in
14 | the /FreeRTOS/Source/portable/RVDS/ARM_CM4F directory.
15 |
16 | If the revision of the ARM Cortex-M7 core is r0p1 then use the FreeRTOS ARM
17 | Cortex-M7 r0p1 port located in the /FreeRTOS/Source/portable/RVDS/ARM_CM7/r0p1
18 | directory.
--------------------------------------------------------------------------------
/Template_FreeRTOS/FreeRTOS/portable/readme.txt:
--------------------------------------------------------------------------------
1 | Each real time kernel port consists of three files that contain the core kernel
2 | components and are common to every port, and one or more files that are
3 | specific to a particular microcontroller and/or compiler.
4 |
5 |
6 | + The FreeRTOS/Source/Portable/MemMang directory contains the five sample
7 | memory allocators as described on the http://www.FreeRTOS.org WEB site.
8 |
9 | + The other directories each contain files specific to a particular
10 | microcontroller or compiler, where the directory name denotes the compiler
11 | specific files the directory contains.
12 |
13 |
14 |
15 | For example, if you are interested in the [compiler] port for the [architecture]
16 | microcontroller, then the port specific files are contained in
17 | FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the
18 | only port you are interested in then all the other directories can be
19 | ignored.

4 |
5 | + The FreeRTOS/Source directory contains the three files that are common to
6 | every port - list.c, queue.c and tasks.c. The kernel is contained within these
7 | three files. croutine.c implements the optional co-routine functionality - which
8 | is normally only used on very memory limited systems.
9 |
10 | + The FreeRTOS/Source/Portable directory contains the files that are specific to
11 | a particular microcontroller and or compiler.
12 |
13 | + The FreeRTOS/Source/include directory contains the real time kernel header
14 | files.

/Template_lib/FreeRTOS/portable/RVDS/ARM_CM7/ReadMe.txt:
--------------------------------------------------------------------------------
1 | There are two options for running FreeRTOS on ARM Cortex-M7 microcontrollers.
2 | The best option depends on the revision of the ARM Cortex-M7 core in use. The
3 | revision is specified by an 'r' number, and a 'p' number, so will look something
4 | like 'r0p1'. Check the documentation for the microcontroller in use to find the
5 | revision of the Cortex-M7 core used in that microcontroller. If in doubt, use
6 | the FreeRTOS port provided specifically for r0p1 revisions, as that can be used
7 | with all core revisions.
8 |
9 | The first option is to use the ARM Cortex-M4F port, and the second option is to
10 | use the Cortex-M7 r0p1 port - the latter containing a minor errata workaround.
11 |
12 | If the revision of the ARM Cortex-M7 core is not r0p1 then either option can be
13 | used, but it is recommended to use the FreeRTOS ARM Cortex-M4F port located in
14 | the /FreeRTOS/Source/portable/RVDS/ARM_CM4F directory.
15 |
16 | If the revision of the ARM Cortex-M7 core is r0p1 then use the FreeRTOS ARM
17 | Cortex-M7 r0p1 port located in the /FreeRTOS/Source/portable/RVDS/ARM_CM7/r0p1
18 | directory.

1 | Each real time kernel port consists of three files that contain the core kernel
2 | components and are common to every port, and one or more files that are
3 | specific to a particular microcontroller and/or compiler.
4 |
5 |
6 | + The FreeRTOS/Source/Portable/MemMang directory contains the five sample
7 | memory allocators as described on the http://www.FreeRTOS.org WEB site.
8 |
9 | + The other directories each contain files specific to a particular
10 | microcontroller or compiler, where the directory name denotes the compiler
11 | specific files the directory contains.
12 |
13 |
14 |
15 | For example, if you are interested in the [compiler] port for the [architecture]
16 | microcontroller, then the port specific files are contained in
17 | FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the
18 | only port you are interested in then all the other directories can be
19 | ignored.

4 |
5 | + The FreeRTOS/Source directory contains the three files that are common to
6 | every port - list.c, queue.c and tasks.c. The kernel is contained within these
7 | three files. croutine.c implements the optional co-routine functionality - which
8 | is normally only used on very memory limited systems.
9 |
10 | + The FreeRTOS/Source/Portable directory contains the files that are specific to
11 | a particular microcontroller and or compiler.
12 |
13 | + The FreeRTOS/Source/include directory contains the real time kernel header
14 | files.

/examples/commonlib/FreeRTOS/portable/RVDS/ARM_CM7/ReadMe.txt:
--------------------------------------------------------------------------------
1 | There are two options for running FreeRTOS on ARM Cortex-M7 microcontrollers.
2 | The best option depends on the revision of the ARM Cortex-M7 core in use. The
3 | revision is specified by an 'r' number, and a 'p' number, so will look something
4 | like 'r0p1'. Check the documentation for the microcontroller in use to find the
5 | revision of the Cortex-M7 core used in that microcontroller. If in doubt, use
6 | the FreeRTOS port provided specifically for r0p1 revisions, as that can be used
7 | with all core revisions.
8 |
9 | The first option is to use the ARM Cortex-M4F port, and the second option is to
10 | use the Cortex-M7 r0p1 port - the latter containing a minor errata workaround.
11 |
12 | If the revision of the ARM Cortex-M7 core is not r0p1 then either option can be
13 | used, but it is recommended to use the FreeRTOS ARM Cortex-M4F port located in
14 | the /FreeRTOS/Source/portable/RVDS/ARM_CM4F directory.
15 |
16 | If the revision of the ARM Cortex-M7 core is r0p1 then use the FreeRTOS ARM
17 | Cortex-M7 r0p1 port located in the /FreeRTOS/Source/portable/RVDS/ARM_CM7/r0p1
18 | directory.

/examples/commonlib/FreeRTOS/portable/readme.txt:
--------------------------------------------------------------------------------
1 | Each real time kernel port consists of three files that contain the core kernel
2 | components and are common to every port, and one or more files that are
3 | specific to a particular microcontroller and/or compiler.
4 |
5 |
6 | + The FreeRTOS/Source/Portable/MemMang directory contains the five sample
7 | memory allocators as described on the http://www.FreeRTOS.org WEB site.
8 |
9 | + The other directories each contain files specific to a particular
10 | microcontroller or compiler, where the directory name denotes the compiler
11 | specific files the directory contains.
12 |
13 |
14 |
15 | For example, if you are interested in the [compiler] port for the [architecture]
16 | microcontroller, then the port specific files are contained in
17 | FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the
18 | only port you are interested in then all the other directories can be
19 | ignored.

4 |
5 | + The FreeRTOS/Source directory contains the three files that are common to
6 | every port - list.c, queue.c and tasks.c. The kernel is contained within these
7 | three files. croutine.c implements the optional co-routine functionality - which
8 | is normally only used on very memory limited systems.
9 |
10 | + The FreeRTOS/Source/Portable directory contains the files that are specific to
11 | a particular microcontroller and or compiler.
12 |
13 | + The FreeRTOS/Source/include directory contains the real time kernel header
14 | files.
