Rebuilding DSP/BIOS Link
Additional Procedures A-11
The <root directory to mount> must match the file system that you set up
on your workstation. For example, /home/<useracct>/workdir/filesys.
When you boot, look for the following lines that confirm the boot mode:
TFTP from server 192.168.160.71; our IP address is
192.168.161.186
Filename 'library/davinci/0.4.2/uImage'.
...
Starting kernel ...
...
VFS: Mounted root (nfs filesystem).
A.5 Rebuilding DSP/BIOS Link
If you want to rebuild the DSP/BIOS Link package, follow these steps
(assuming you are using the bash shell):
1) Edit the davinci_mvlpro5.0.mk file, which is in the
/home/<useracct>/dvsdk_#_#/dsplink_#/packages/dsplink/make/Linux/
directory, to make sure the BASE_BUILDOS and BASE_CGTOOLS
variables correctly point to the correct locations. For example:
BASE_BUILDOS := /home/<useracct>/workdir/lsp/ti-davinci/linux-2.6.18_pro500
BASE_CGTOOLS := /opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/bin
2) Define the DSPLINK environment variable to be the absolute path to
the "dsplink" directory. (Use export for bash shell, and setenv for tcsh
shell.) For example:
host $ export DSPLINK=/home/<useracct>/dvsdk_#_#/dsplink_#/packages/dsplink
3) Move to the Linux build script directory:
host $ cd $DSPLINK/etc/host/scripts/Linux
4) Build DSP/BIOS Link as follows:
host $ sh –f buildmodule.sh
5) The rebuilt kernel module is called dsplinkk.ko. It is located in the
$DSPLINK/gpp/export/BIN/Linux/Davinci/DM6446/RELEASE/
directory.
