Hi all,

Our system have one DSP and one ARM and system will boot with DSP  then DSP  should load ARM executable in ARM program memory.  how to do this ?.
We tried the following, but unable to succeed .
1] build the ARM code(which has boot code also), it will generate '.out ' executable
2] convert '.out ' executable into binary using hex470.exe .
3] From DSP read generated binary file and copy into arm program memory.

I think we are missing something like we need get address of each sections like .text , .data etc.. according to that we need to copy(is it right??). But how to get this address location information?
Or is there any procedure to do that?

Thank you,
Vicky

    To generate ARM executable .out file we used cl470.exe and to convert .out to .bin we used hex470.exe.
    And you told about RVCT tools, i don't have idea about this, where can i get information about this.. or can u please explain little more..?


    RVCT is the name of the tools that are being developed by ARM.  (See: [url="http://www.arm.com/products/DevTools/RVCT.html)"]http://www.arm.com/products/DevTools/RVCT.html)[/url]  It has a tool that lets you examine the files it outputs.  Such a tool may exist in your tools.

    I don't know about cl470.exe.  Google suggests this is part of the TMS470 toolchain.  I'm afraid you'll need to look in their documentation to find out if they have a tool you can use to extract the information you need.  Or maybe someone else here can help...
