Can't execute a simple test application on my AM335x Starter Kit

Hello,


I've recently updated to SDK 08 version with CCS v6 to use for development on my AM335x Starter Kit. I've created a simple hello world program and setup debugging it following the steps in  processors.wiki.ti.com/index.php/Linux_Debug_in_CCSv5 in Run Mode. Although a little different in CCS v6, it is relatively the same.

My problem is I keep getting a "No such file or directory" error message from the gdbserver when trying to execute code on the target but I'm 100% certain the file is there as I can see it if I go on the console and  on putty (using ssh). I've doubled check if the executable compatibility with the target with the "file" command and it gave me "ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.31, not stripped" which is seem fine. I get the same error if I try to execute the binary directly from terminal. It may be a compatibility issue but I can't think of how to find out, since the error message reported doesn't tell much.


Any ideas ?

Thanks,

LM

    You are missing a shared library on the target. Use the ldd command to check.

    I don't have ldd installed but I've used objdump -p instead which gave me this:

    root@am335x-evm:~# objdump -p simpleone

    It says it needs libc.so.6 and I have it in the /lib folder on the target.

    Any thoughts ?

    I have actually no clue what is going on. Might revert to a previous sdk version and see if I can get something working...

    Ok got it to work. Had to made sure to save the compiled filesystem and kernel from SDK 0.8 to the SD card which I thought I did but not. Now I have a system I can start playing with !
