Texas Instruments TMS320DM357 DVEVM v2.05 manual Setting Up the Build/Development Environment

Setting Up the Build/Development Environment

4.4Setting Up the Build/Development Environment

To set up the development and build environment, follow these steps:

1)Log in to your user account (and not as root) on the NFS host system.

2)Set your PATH so that the MontaVista tool chain host tools and cross compiler (arm_v5t_le-gcc) can be found. For example, in a default installation of the MontaVista LSP, you should add a definition like the following to your shell resource file (for example, ~/.bashrc):

PATH="/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/bin: /opt/mv_pro_5.0/montavista/pro/bin:

/opt/mv_pro_5.0/montavista/common/bin:$PATH"

If you installed in a location other than /opt/mv_pro_5.0, use your own location in the PATH.

3)Remember to use the following command after modifying your

.bashrc file:

host $ source ~/.bashrc

4.4.1Writing a Simple Program and Running it on the EVM

Make sure you have performed the steps in Section 4.3.4, Exporting a

Shared File System for Target Access and Section 4.4, Setting Up the

Build/Development Environment.

Perform the following steps on the NFS host system as user (not as root):

1)host $ mkdir /home/<useracct>/workdir/filesys/opt/hello

2)host $ cd /home/<useracct>/workdir/filesys/opt/hello

3)Create a file called hello.c with the following contents:

#include <stdio.h>

int main() { printf("Buongiorno DaVinci!\n"); return 0;

}

4)host $ arm_v5t_le-gcc hello.c -o hello

Perform the following steps on the target board. You may use either the target's console window (Section 2.2) or a telnet session.

1)target $ cd /opt/hello

2)Run ./hello. The output should be:

Buongiorno DaVinci!
