The minimal variant became quite meaningless lately. There were two port APIs originally that had extra functions in the default port in addition to the core-mandated implementations: the I/O and Termination port APIs. However, the extra Termination API code was removed a year ago, leaving some minimal extension in the I/O port only. As the overhead of the extension is negligible, it is not worth maintaining two library variants. Therefore - this commit removes the minimal variant of the default port lib, - rewrites uses of the minimal variant to use the variant with the I/O extension, and - updates targets where I/O port code was copy-n-pasted.

About
This folder contains files to run JerryScript on RIOT-OS with STM32F4-Discovery board.
How to build
1. Preface
1, Directory structure
Assume harmony as the path to the projects to build.
The folder tree related would look like this.
harmony
+ jerryscript
| + targets
| + riot-stm32f4
+ RIOT
2, Target board
Assume STM32F4-Discovery with BB as the target board.
2. Prepare RIOT-OS
Follow this page to get the RIOT-OS source.
Follow the Inroduction wiki site and also check that you can flash the stm32f4-board.
3. Build JerryScript for RIOT-OS
# assume you are in harmony folder
cd jerryscript
make -f ./targets/riot-stm32f4/Makefile.riot
This will generate the following libraries:
/build/bin/release.riotstm32f4/librelease.jerry-core.a
/build/bin/release.riotstm32f4/librelease.jerry-libm.lib.a
This will copy one library files to targets/riot-stm32f4/bin folder:
libjerrycore.a
This will create a hex file in the targets/riot-stm32f4/bin folder:
riot_jerry.elf
4. Flashing
make -f ./targets/riot-stm32f4/Makefile.riot flash
For how to flash the image with other alternative way can be found here: Alternative way to flash
5. Cleaning
To clean the build result:
make -f ./targets/riot-stm32f4/Makefile.riot clean
5. Running JerryScript Hello World! example
You may have to press RESET on the board after the flash.
You can use minicom for terminal program, and if the prompt shows like this:
main(): This is RIOT! (Version: ****)
You are running RIOT on a(n) stm32f4discovery board.
This board features a(n) stm32f4 MCU.
please set Add Carriage Ret option by CTRL-A > Z > U at the console, if you're using minicom.
Help will provide a list of commands:
> help
The test command will run the test example, which contains the following script code:
print ('Hello, World!');
