Userspace app run error

[hawkinzhang]

Hi,NXP

 I build toolchain in /QorIQ-SDK-V2.0-20160527 by fellow command:

1. bitbake fsl-image-full
2. bitbake fsl-toochain

Then i get toolchain SDK in folder : QorIQ-SDK-V2.0-20160527-yocto/build_ls1043ardb/tmp/deploy/sdk

Then i install toolchain by follow command:

1.  ./fsl-qoriq-glibc-x86_64-aarch64-toolchain-2.0.sh
2. cd /opt/hazhang/fsl_ls1043_arm_sdk2.0_64bit
3. source environment-setup-aarch64-fsl-linux

Then i build my test app helloworld by toolchain:

1. $CC hello.c -o hello
2. file hello
   hello: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 3.14.0, BuildID[sha1]=d041641cf48b10fdd9751fa115a24eb1aedd346d, not stripped

Then i copy hello to NXP's board : LS1043ARDB

./hello  but failed,trace as fellow:

1. file hello
   hello: ERROR: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1 error reading (Invalid argument)

Thanks for yout attention!

Perhaps you use tftp for elf file transfers.

The tftp32 software as tftp server under Windows uses binary transfers.

The LS1043ARDB tftp client default mode is "netascii".

Different modes between TFTP server and TFTP client produce incorrect data transfers.

Check MD5 checksum on your board and on your PC.

Have a great day,

thanks a lot ， This is exactly the problem!

It looks like that there is a error in your "hello" program.

Check your code. For example see below message if simple "Hello World" program is used:

file test.elf

test.elf: ELF 64-bit LSB  executable, ARM aarch64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 3.14.0, BuildID[sha1]=36edfe9836908527be085de3aefafa67dea93c12, not stripped

hi Pavel:

   I have met the same problem mentioned by zhang. My demo board is also LS1043, all my operations are same as his. I have checked my "helloword" :

#include <stdio.h>

int main()
{
         printf("hello world !\n");

         return 0;
}

obviously there is no error in my program , I  wonder how to solve this problem .

Thanks for yout attention!
