Simple hello world on Beaglebone

DavidVescovi

I was looking to build a simple Hello World app for the Beaglebone with CCS 5.3. I installed the am335x SDK and CSS as described at http://processors.wiki.ti.com/index.php/Code_Composer_Studio_v5_Users_Guide

All is fine and I can cross compile with no errors. I also set up Remote System Explorer as described http://processors.wiki.ti.com/index.php/How_to_setup_Remote_System_Explorer_plug-in This also works fine I have good connection to BeagleBone and I can copy files and remote shell also works.

There is already a hello app on the device I assume from the original kernel build. If I execute this from the remote shell I get the standard "Hello World" prompt feedback. If I copy my release build "MyHello" to /usr/bin and mark it as executable then try to run it I get:

-sh: /usr/bin/MyHello: No such file or directory

I can clearly see the file Is there both from the remote explorer and locally from the BB GUI.

What is up?

Hi David,

Check the permissions for the file. When I copy a program to the remote target, I need to set the execute permissions before I can run it.

Thanks

Another thing to check: did you generate this file using GCC for Linux (typically arm-none-Linux-gnueabi-gcc) or the TI compiler (armcl) or the baremetal Linaro (arm-none-eabi-gcc)? You should use the first for that.

Actually I tried building with the Linaro tool chain (As described in the CCS user manual) and the gcc tool chain. They both fail the same way ...MyHello: command not found

I even tried coping to SD card and using that. Still no luck.
