Rebuilding the DVEVM Software for the Target
4-14
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.
4.6 Rebuilding 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_

/montavista/pro/devkit/arm/
