Texas Instruments TMS320DM357 DVEVM v2.05 manual 4.6Rebuilding the DVEVM Software for the Target

Rebuilding the DVEVM Software for the Target

7)If the kernel is configured with any loadable modules (that is, selecting <M> for a module in menuconfig), use the following commands to rebuild and install these modules:

host $ make ARCH=arm CROSS_COMPILE=arm_v5t_le- modules

host $ make ARCH=arm CROSS_COMPILE=arm_v5t_le-

INSTALL_MOD_PATH=/home/<useracct>/workdir/filesys modules_install

8)Use the following command to copy uImage to a place where U-Boot can use TFTP to download it to the EVM. These commands assume you are using the default TFTP boot area, which is /tftpboot. If you use another TFTP root location, please change /tftpboot to your own TFTP root location. (Perform these commands as root or use a chown uImage command to get ownership of the file.)

host $ cp /home/<useracct>/workdir/lsp/ti-davinci/linux_2.6.18_pro500/arch/arm/boot/uImage /tftpboot

host $ chmod a+r /tftpboot/uImage

For more information on setting up a TFTP server, see Section A.3.

See a standard Linux kernel reference book or online source for more about Linux build configuration options.

4.6Rebuilding the DVEVM Software for the Target

To place demo files in the /opt/dvevm directory, you need to rebuild the

DVEVM 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 dvsdk_#_#/Rules.make file.

■Set PLATFORM to match your EVM board as follows:

PLATFORM=dm357

■Set DVSDK_INSTALL_DIR to the top-level DVEVM 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/dm357

■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
