# FreeRTOS Demo for the NEORV32 Processor
This example shows how to run [FreeRTOS](https://www.freertos.org/) on the NEORV32 processor. It features the default
"blinky_demo" and the more sophisticated "full_demo" demo applications. See the comments in `main.c` and the according
source files for more information.
The chip-specific extensions folder (`chip_specific_extensions/neorv32`) should be in `$(FREERTOS_HOME)/Source/portable/GCC/RISC-V/chip_specific_extensions`,
but is placed in this source directory for simplicity.
## Hardware Requirements
* DMEM/IMEM requriements depend on the actual application (for example: 8kB DMEM and 16kB IMEM for *blinky_demo*)
* MTIME (machine timer) + UART + GPIO
* `Zicsr` CPU extension
## Instructions
Download FreeRTOS from the [official GitHub repository](https://github.com/FreeRTOS/FreeRTOS) or from the its official homepage.
$ git clone https://github.com/FreeRTOS/FreeRTOS.git
Open the makefile from this example folder and configure the `FREERTOS_HOME` variable to point to your FreeRTOS home folder.
FREERTOS_HOME ?= /mnt/n/Projects/FreeRTOSv10.4.1
Compile the NEORV32 executable. Do not forget the `RUN_FREERTOS_DEMO` switch.
$ make USER_FLAGS+=-DRUN_FREERTOS_DEMO clean_all exe
Note: The *.c sources and the FreeRTOS-specific part of the makefile have (include) guards that test if `RUN_FREERTOS_DEMO` is defined.
This has no pratical usage for the user - it is just a work-around for the NEORV32 CI environment.
Upload the executable (`neorv32_exe.bin`) to the processor via the bootloader and execute it.
```
Awaiting neorv32_exe.bin... OK
CMD:> e
Booting...
FreeRTOS V10.4.1
Blink
Blink
Blink
```
## FreeRTOS Plus
To automatically add source and include files from FreeRTOS plus extensions add one (or more) of the following arguments when invoking `make`:
* FreeRTOS-Plus-CLI: `USER_FLAGS+=-FREERTOS_PLUS_CLI`
* FreeRTOS-Plus-TCP: `USER_FLAGS+=-FREERTOS_PLUS_TCP`
Example:
$ make USER_FLAGS+=-DRUN_FREERTOS_DEMO USER_FLAGS+=-FREERTOS_PLUS_TCP clean_all exe
## Notes
The onfiguration of the FreeRTOS home folder (via `FREERTOS_HOME`) is corrupted if the compiler shows the following error:
```
main.c:36:10: fatal error: FreeRTOS.h: No such file or directory
36 | #include <FreeRTOS.h>
| ^~~~~~~~~~~~
compilation terminated.
make: *** [makefile:203: main.c.o] Error 1
```

* The FreeRTOS kernel's RISC-V port is split between the the code that is
* common across all currently supported RISC-V chips (implementations of the
* RISC-V ISA), and code that tailors the port to a specific RISC-V chip:
*
* + FreeRTOS\Source\portable\GCC\RISC-V-RV32\portASM.S contains the code that
* is common to all currently supported RISC-V chips. There is only one
* portASM.S file because the same file is built for all RISC-V target chips.
*
* + Header files called freertos_risc_v_chip_specific_extensions.h contain the
* code that tailors the FreeRTOS kernel's RISC-V port to a specific RISC-V
* chip. There are multiple freertos_risc_v_chip_specific_extensions.h files
* as there are multiple RISC-V chip implementations.
*
* !!!NOTE!!!
* TAKE CARE TO INCLUDE THE CORRECT freertos_risc_v_chip_specific_extensions.h
* HEADER FILE FOR THE CHIP IN USE. This is done using the assembler's (not the
* compiler's!) include path. For example, if the chip in use includes a core
* local interrupter (CLINT) and does not include any chip specific register
* extensions then add the path below to the assembler's include path:
* FreeRTOS\Source\portable\GCC\RISC-V-RV32\chip_specific_extensions\RV32I_CLINT_no_extensions
