Note: This is a continuation of Nios® V Processor Installation and Hello World Execution, Part 1

5. Software Construction & Execution

The current types of Board Support Packages (BSP) available are hal, ucosii, and freertos. I will introduce the steps for generating, building, and executing each BSP.

5.1 HAL Version

5.1.1 Generating the Board Support Package (BSP)

For generating the BSP, specify hal with the --type option in the BSP generation command. Please enter the following command:

 

niosv-bsp -c --quartus-project=hw/top.qpf --qsys=hw/sys.qsys --type=hal sw/bsp_hal/settings.bsp

 

Output:

5.1.2 Generating CMafileLists.txt

Execute the following command to generate the CMafileLists.txt required for compiling the application. If the source file specified in --srcs is not present in the path, an error will occur.

 

niosv-app --bsp-dir=sw/bsp_hal --app-dir=sw/app_hal --srcs=sw/app_hal --elf-name=hello.elf

 

Output:

 

2023.11.27.17:23:52 Info: Elf name is set to "hello.elf".
2023.11.27.17:23:52 Info: Source file "hello.c" added from directory "sw/app_hal".
2023.11.27.17:23:52 Info: "sw/app_hal/CMakeLists.txt" was generated.

 

5.1.3 Generating MakeFile

Execute the following command to generate MakeFile from CMakeLists.txt. Since we are specifying the existing directory sw/app_hal/build as the build directory, you need to delete sw/app_hal/build/CMakeCache.txt first.

 

rm sw/app_hal/build/CMakeCache.txt

 

Then generate the MakeFile.

 

cmake -S sw/app_hal -G "Unix Makefiles" -B sw/app_hal/build

 

Output:

5.1.4 Generating hello.elf

Execute the following command to generate hello.elf.

 

make -C sw/app_hal/build

 

Output:

5.1.6 Resetting the CPU by ISSP (In-System Source & Probe)

As explained during the design creation, the reset signal in this design is connected to ISSP. Reset the design by toggling the reset signal through ISSP. For more information about ISSP, refer to 2.3.1. In-System Sources and Probes. Execute the following command to reset the design.

 

quartus_stp -t scripts/toggle_issp.tcl

5.1.7 Displaying "Hello world" on the Terminal

Execute the following command to display messages from the JTAG-UART implemented in the design on the host terminal. The JTAG-UART waits until communication with the host is established, so you can confirm that the messages start from the beginning. Press "CTRL+C" to exit.

 

juart-terminal

 

Output:

5.2 uC/OS-II Edition

Next, we will compile and execute the uC/OS-II sample.

5.2.1 Generating Board Support Package (BSP)

Use the following command to generate a BSP for uC/OS-II. The BSP settings file sw/bsp_ucosii/settings.bsp is prepared. Specify ucosii for the Type.

 

niosv-bsp -c --quartus-project=hw/top.qpf --qsys=hw/sys.qsys --type=ucosii sw/bsp_ucosii/settings.bsp

5.3 FreeRTOS™ Edition

Next, let's compile and run the FreeRTOS™ sample.

5.3.1 Generating Board Support Package (BSP)

Use the following command to generate a BSP for FreeRTOS™. The BSP settings file sw/bsp_freertos/settings.bsp is prepared. Specify freertos for the Type.

 

niosv-bsp -c --quartus-project=hw/top.qpf --qsys=hw/sys.qsys --type=freertos sw/bsp_freertos/settings.bsp

 

Output:

5.3.2 Generating CMafileLists.txt

Generate CMakefileLists.txt. Use the application directory and source code for FreeRTOS™ available in sw/app_freertos.

 

niosv-app --bsp-dir=sw/bsp_freertos --app-dir=sw/app_freertos --srcs=sw/app_freertos --elf-name=hello_freertos.elf

 

Output:

 

2023.11.28.01:12:10 Info: Elf name is set to "hello_freertos.elf".
2023.11.28.01:12:10 Info: Source file "hello_freertos.c" added from directory "sw/app_freertos".
2023.11.28.01:12:10 Info: "sw/app_freertos/CMakeLists.txt" was generated.

 

5.3.3 Generating Makefile

Execute the following command to generate a Makefile from CMakeLists.txt. You need to delete sw/app_freertos/build/CMakeCache.txt if it's the first generation.

 

rm sw/app_freertos/build/CMakeCache.txt

 

Then generate the Makefile.

 

cmake -S sw/app_freertos -G "Unix Makefiles" -B sw/app_freertos/build

 

Output:
