Verifying the Firmware Programmed Successfully – Running the Linux Apps
The RTC software provided by Z3 includes a portion that runs on the ARM processor of the module. This software
allows the user to verify the RTC is working and to set the date and time. The software is packaged in the “rtc.tar.gz”
file provided in this release. The steps below detail where to copy these files and how to build and use it.
5.1 Building the software
(1) Go to the project directory and type “source z3-env” (make sure “z3-env” and “z3apps” are in this directory)
# ls {note: actual contents may be slightly different}
build-tools factory images makeall.sh sysapps u-boot z3-env
dvr-rdk filesys kernels Makefile toolchain z3apps
# source ./z3-env
(2) Go to the z3apps/app directory and copy the rtc.tar.gz file there.
# cd z3apps/app
# cp {wherever rtc.tar.gz currently is} .
(3) Untar the rtc.tar.gz file
# gzip –d rtc.tar.gz
# tar –xvf rtc.tar
(4) Go into the rtc directory just created
# cd rtc
(5) Type “make clean all install”
# make clean all install
(6) The RTC files should now be at $ROOTFS/fs/usr/local/bin and ready to use when the board is rebooted.
