DE1-SOC 'My_First_HPS' -- Hello World!

Hi

From the looks of it you have successfully boot into the linux environment.

The error message that you are looking at means that the "hello world" application crashed when the application launches.

It means that the application itself is faulty, there are multiple factors that could cause this.

I would not be alarm at this as the hello world is just a simple program in to print something in the linux environment, it does not indicate that there are something wrong with the board it self.

May I ask what is the end goal that you are looking at?

Regards

Hi,

Thank you for your response. My end goal is to become familiarized with writing and compiling my own application to run on the DE1-SOC board. I am starting from my_first_hps tutorial as way to setup all the tools and work my way through running the first application on the DE1-SOC board. Although I am not concerned with any hardware related issue as the source of the problem, I am trying to determine the reason why this simple program would be faulty, even though I have followed the steps from my_first_hps tutorial as closely as possible. Without resolving this issue, I assume I cannot complete any other tutorial or exercise that involves applications running on the HPS. Thus, why I am trying to get to the root cause of this application crash. Thank you.

Hi

Did you meet any issue when running the make command on your host pc?

And did the application successfully copied over to the board?

Could you issue "ls -l" to check the size of the application on the board?

Hi

I see that the compiler that are using is not the cross compiler that was describ in the tutorial.

That could be the reason the application could not be run on the linux device.

Could you try using the describe cross compiler "arm-linux-gnueabihf".

Hi

Sorry for the late reply.

Could you try out the adding the compiler to the PATH variable so that it could find the correct compiler

After going into the gcc folder and entering the command below:

"export PATH=`pwd`/gcc-linaro-7.5.0-2019.12-i686-mingw32_arm-eabi/bin:$PATH"

After that could you try the make file again.

Hi

Are you able to launch the correct compiler after adding the path into the system environment?

Hi,

I tried entering the export path in the 'gcc' folder, but it indicated that the path cannot be found. Below see below.

C:\intelFPGA\20.1\embedded\host_tools\linaro\gcc>"export PATH=`pwd`/gcc-linaro-7.5.0-2019.12-i686-mingw32_arm-eabi/bin:$PATH"
The system cannot find the path specified.

And below are the sub-folders and files under the 'gcc' folder...

Hi

Could you please try downloading the linaro toolchain with the command below:

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

Once finish please try the make command again this time with

make

arm-none-linux-gnueabihf-gcc -g -Wall -Dsoc_cv_av -IC:/intelFPGA/20.1/embedded/ip/altera/hps/altera_hps/hwlib/include/soc_cv_av -IC:/intelFPGA/20.1/embedded/ip/altera/hps/altera_hps/hwlib/include/ -c main.c -o main.o

arm-eabi-gcc -g -Wall main.o -o my_first_hps

instead of the the arm-eabi-gcc or arm-linux-gnueabihf-gcc

Hi,

I followed the instruction as indicated. And, below is the sub-directory that was created under the 'linaro' folder.

/cygdrive/c/intelFPGA/20.1/embedded/host_tools/linaro
$ ls
gcc install_linaro.sh
gcc-arm-11.2-2022.02-x86_64-arm-none-linux-gnueabihf newlib
gcc-linaro-7.5.0-2019.12-i686-mingw32_arm-eabi.tar.xz newlib-cygwin

However, when executing the 'make' command, I got the following error message:

$ make
arm-none-linux-gnueabihf-gcc -g -Wall -Dsoc_cv_av -IC:/intelFPGA/20.1/embedded/ip/altera/hps/altera_hps/hwlib/include/soc_cv_av -IC:/intelFPGA/20.1/embedded/ip/altera/hps/altera_hps/hwlib/include/ -c main.c -o main.o
process_begin: CreateProcess(NULL, arm-none-linux-gnueabihf-gcc -g -Wall -Dsoc_cv_av -IC:/intelFPGA/20.1/embedded/ip/altera/hps/altera_hps/hwlib/include/soc_cv_av -IC:/intelFPGA/20.1/embedded/ip/altera/hps/altera_hps/hwlib/include/ -c main.c -o main.o, ...) failed.
make (e=2): The system cannot find the file specified.
make: *** [main.o] Error 2

Please advise. Thanks.

Hi,

FYI - I also tried renaming the /gcc-arm-11.2-2022.02-x86_64-arm-none-linux-gnueabihf subfolder to /gcc, and then tried running the make file. This time I got the following error message:

$ make
arm-none-linux-gnueabihf-gcc -g -Wall -Dsoc_cv_av -IC:/intelFPGA/20.1/embedded/ip/altera/hps/altera_hps/hwlib/include/soc_cv_av -IC:/intelFPGA/20.1/embedded/ip/altera/hps/altera_hps/hwlib/include/ -c main.c -o main.o

make (e=193): Error 193
make: *** [main.o] Error 193

Hope this provides you more information as to what the problem may be.
