Rebuilding the DVEVM Software for the Target

4.6Rebuilding the DVEVM Software for the Target

To place demo files in the /opt/dvsdk/dm6446 directory, you need to rebuild the DVSDK software. To do this, follow these steps:

1)If you have not already done so, rebuild the Linux kernel as described in Section 4.5.

2)Change directory to dvsdk_#_#.

3)Edit the Rules.make file in the dvsdk_#_#. directory.

■ Set PLATFORM to match your EVM board as follows:

PLATFORM=dm6446

■Set DVSDK_INSTALL_DIR to the top-level DVSDK installation directory as follows:

DVSDK_INSTALL_DIR=/home/<useracct>/dvsdk_#_#

■Make sure EXEC_DIR points to the opt directory on the NFS exported file system as follows:

EXEC_DIR=/home/<useracct>/workdir/filesys/opt/dvsdk/$(PLATFORM)

■Make sure MVTOOL_DIR points to the MontaVista Linux tools directory as follows:

MVTOOL_DIR=/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le

■Make sure LINUXKERNEL_INSTALL_DIR is defined as follows:

LINUXKERNEL_INSTALL_DIR=/home/<useracct>/workdir/lsp/ti-davinci/linux-2.6.18_pro500

■Modify the following environment variables as needed to match the locations of these components on your Linux host. We recommend that these components be installed in the /home/<useracct>/dvsdk_#_# directory, but you may have installed them elsewhere.

BIOS_INSTALL_DIR=/home/<useracct>/dvsdk_#_#/bios_#_#

FC_INSTALL_DIR=/home/<useracct>/dvsdk_#_#/fc_#_#

XDC_INSTALL_DIR=/home/<useracct>/dvsdk_#_#/xdctools_#_#

4)While in the same directory that contains Rules.make, use the following commands to build the DVSDK demo applications and put the resulting binaries on the target file system specified by EXEC_DIR.

host $ make clean

host $ make

host $ make install
