How to compile a simple "Hello world" program for FRDM-LS1012A board using CodeWarrior?

[alenagrigorieva]

I have FRDM-LS1012A board. I ddin't change/update anything on it, it has configuration as delivered. I downloaded latest version of CodeWarrior for ARMv8 and tried to create a simple "Hello world" program.  All sample programs do compile, but don't execute on my board. I get "exec format error". When I looked at preferences I saw that target processor is Cortex-M3, and it can't be changed. Then I tried to create a new project. There is a possibility to choose a target processor, but there is no Cortex-A53 in the drop-down list. What should I do?

I work on Windows 7.

If you want to run your example under Linux, use Linux Apllication Debug project or SDK toolchain.

Your Bare board project can be using under Linux.

This project contains memory initialization code and will not work under Linux.

Look at the Section 2.3.2 of the ARMv8_Targeting_Manual.pdf file. This file is available using the following path in CodeWarrior folder:

C:\Freescale\CW4NET_v2016.01\CW_ARMv8\ARMv8\Help\PDF

Use .o file for loading if this project is used.

Have a great day,

Hello!

Sample Linux programs don’t execute either.

Hello C sample program, Debug version gives the following error message:

root@ls1012afrdm:~# exec ./hellol.elf

If I try to execute main.o from Debug/src I get “-sh: ./main.o: cannot execute binary file: Exec format error”

If I try Release version, I get “-sh: ./hellol.elf: cannot execute binary file: Exec format error” or “-sh: ./main.o: cannot execute binary file: Exec format error”

Your SDK doesn’t support Cygwin. When I try to execute ./sources/meta-freescale/scripts/host-prepare.sh I get error message “Error: Unsupported Distribution, Exit”

I assume you wanted to say “Bare board project can NOT be used under Linux”

Any more ideas? How can I compile a simple application?

It turned out to be a problem with ftp mode(text/binary) of ftpserver.
