DE1-SOC 'My_First_HPS' -- Hello World!

Hi

I just tried out the flow for building the application and did not met any error in the process.

Let me share the steps I have done.

1. Download the compiler toolchain.

wget https://developer.arm.com/-/media/Files/downloads/gnu/11.2-2022.02/binrel/gcc-arm-11.2-2022.02-x86_64-arm-none-linux-gnueabihf.tar.xz

tar xf gcc-arm-11.2-2022.02-x86_64-arm-none-linux-gnueabihf.tar.xz

rm gcc-arm-11.2-2022.02-x86_64-arm-none-linux-gnueabihf.tar.xz

export PATH=`pwd`/gcc-arm-11.2-2022.02-x86_64-arm-none-linux-gnueabihf/bin:$PATH

export CROSS_COMPILE=arm-none-linux-gnueabihf-

2. Download the hwlibs. Starting from 20.1 quartus version it is no longer added together with quartus. (https://www.rocketboards.org/foswiki/Documentation/HWLib#SoC_Abstraction_Layer_40SoCAL_41)

git clone https://github.com/altera-opensource/intel-socfpga-hwlib

cd intel-socfpga-hwlib/tools

./install_linaro.sh

3. Make changes to the make file to point to the new hwlib directory. I have attached the copy I am using.

4. Make should run without error. Attached the application that compiled by me. I have not tested out, could you try it out on your device?

Hi,

I followed your exact instructions to install the tools. If i would also do the two export path commands that you provided, then I would get the following error:

$ make
arm-none-linux-gnueabihf-gcc -g -Wall -Dsoc_cv_av -I/cygdrive/c/intelFPGA/20.1/embedded/host_tools/linaro/intel-socfpga-hwlib/armv7a/hwlib/include/soc_cv_av -I/cygdrive/c/intelFPGA/20.1/embedded/host_tools/linaro/intel-socfpga-hwlib/armv7a/hwlib/include -c main.c -o main.o
process_begin: CreateProcess(NULL, arm-none-linux-gnueabihf-gcc -g -Wall -Dsoc_cv_av -I/cygdrive/c/intelFPGA/20.1/embedded/host_tools/linaro/intel-socfpga-hwlib/armv7a/hwlib/include/soc_cv_av -I/cygdrive/c/intelFPGA/20.1/embedded/host_tools/linaro/intel-socfpga-hwlib/armv7a/hwlib/include -c main.c -o main.o, ...) failed.
make (e=2): The system cannot find the file specified.
make: *** [main.o] Error 2

On the other hand, if I would skip doing the export path commands, then the make run would be successful, as shown below.

$ make
gcc -g -Wall -Dsoc_cv_av -I/cygdrive/c/intelFPGA/20.1/embedded/host_tools/linaro/intel-socfpga-hwlib/armv7a/hwlib/include/soc_cv_av -I/cygdrive/c/intelFPGA/20.1/embedded/host_tools/linaro/intel-socfpga-hwlib/armv7a/hwlib/include -c main.c -o main.o
gcc -g -Wall main.o -o my_first_hps-fpga

The output would be a .exe file as shown below.

$ ls
main.c main.o Makefile 'Makefile - Copy' my_first_hps-fpga.exe

I copied the my_first_hps-fpga.exe over onto the board SD card, and I tried running it. It gave me the following error:

root@socfpga:~# ./my_first_hps-fpga.exe
-sh: ./my_first_hps-fpga.exe: cannot execute binary file

I also tried running the application that you had compiled with the following error.

root@socfpga:~# ./my_first_hps-fpga
./my_first_hps-fpga: /lib/libc.so.6: version `GLIBC_2.34' not found (required by ./my_first_hps-fpga)

Hi

I see that you are running the compilation in a windows environment.

Did you run it in the msys2 ? (https://www.msys2.org/)

https://www.rocketboards.org/foswiki/Documentation/HWLib#Windows_Installation

I managed to run it without the error you are seeing

Could you try the binary compiled using the arm-linux-gnueabihf as suggested from the how-to attached.

I downloaded the compiler with the link below:

https://releases.linaro.org/components/toolchain/binaries/latest-5/arm-linux-gnueabihf/

and exported the following env var.

export PATH=`pwd`/gcc-linaro-5.5.0-2017.10-i686-mingw32_arm-linux-gnueabihf/bin:$PATH

export CROSS_COMPILE=arm-linux-gnueabihf-
