    Hi,

    Sorry for the inconvenience previous msg not editable. So, I am again writing for the reply section.

             I am used to AM62x GP Board and then ti-processor-sdk-linux-am62xx-evm-09.00.00.03 How to compile rpmsg_char_simple.c file. I followed the readme file compiling done every command is running successfully. I copy the compiled binary file in my processor SDK and paste usr/bin location. Power up my board then I put the comment  rpmsg_char_simple -r 9 -n 10 then coming error I attached below.

    root@am62xx-evm:~# rpmsg_char_simple -r 9 -n 10
-sh: /usr/bin/rpmsg_char_simple: cannot execute binary file: Exec format error
root@am62xx-evm:~# uname -a
Linux am62xx-evm 6.1.33-g40c32565ca #1 SMP PREEMPT Thu Jul  6 14:17:24 UTC 2023 aarch64 aarch64 aarch64 GNU/Linux
root@am62xx-evm:~#

    ti_rpmsg_char download link: git clone git://git.ti.com/rpmsg/ti-rpmsg-char.git

    compiled same below readme file only:

     1. Configure the autotools with necessary host and optional prefix to be
    used to install the build libraries and executables
      cd <ti-rpmsg-char-dir>
      autoreconf -i
      ./configure --host=aarch64-none-linux-gnu --prefix=<target-dir>
 2. Build and Install Library
      make
      make install
 3. Build Examples, the top-level Makefile builds only the library by
    default
      make -C examples
      make -C examples install

    How to fix this problem.

    Regards,

    Hi Nick,

          Previously I asked for this basic error only but did not solve the thread so I created this thread.

    Today I solved this architecture error. I change two commands: 

    1. sudo apt install gcc make gcc-aarch64-linux-gnu binutils-aarch64-linux-gnu

    2. ./configure --build x86_64-pc-linux-gnu --host aarch64-linux-gnu

    readme configure command remove put this command is working fine with no error.

    ok, no problem. 

    Regards,
