+Look in the file truss/packages/mtcdt/README.txt and
+truss/image/README.txt.
+
+The ipk files needed for the upgrade should be built,
+and then all the files not needed for the upgrade should
+be removed, and then bitbake package-index run.
+
+The mtcdt or mtcap directory can be copied into the
+truss/packages/mtcdt or mtcap directory.  If mtcap
+is used, the install.sh script will need modification.
+
+The kernel image from build/tmp/deploy/images/mtcdt
+(or mtcap) can be copied into the image directory.
+
+truss could be renamed to suit the kernel name and
+version.  For instance kernel-3.12.70-r17.1.
+
+A tar file is then created with the truss name as the
+root of the tar.

+install.txt    What the install should look like
+kernel-*.tar  Tar file with the packages and kernel image.
+
+1.  Copy kernel-*.tar and *.md5 to the Conduit directory /var/volatile.
+    scp or winscp would be good.  User mtadm.
+
+2.  Log into Conduit
+
+3.  cd /var/volatile
+
+4.  md5sum -c *.md5
+
+5.  tar -xf kernel-*.tar
+
+6.  cd kernel-*
+
+7.  sudo ./install.sh
+
+This will take about 20 minutes.
+
+The install must not be interrupted.  opkg does not always clean up after an
+aborted install.
+
+At this point the kernel image is installed, followed by the module packages.
+If there are errors you should see messages:
+ERROR: ...
+
+There is a log in file /tmp/opkglog*
+
+The log must be copied from the Conduit before rebooting if there are issues.
+
+7.  sudo reboot
+
+8.  New kernel can be verified:
+
+uname -r
+
+(Old kernel is 3.12.27)
+
+Packages can be verified:
+
+opkg list-installed | fgrep '3.12.70'
