Other Parts Discussed in Thread: AM3352, TPS65910
HI All,
we follow so many wiki links.But those links are older versions.
we are using latest ti-processor sdk-3.00.04 .our boot optimizaiton time is 5 sec.we optimized u-boot and kernel .But we are not optimized rootfs systemd services.our logs below please find the below logs give me idea.
we removed so many systemd services from /lib/systemd/system/.services.
still we need to remove some systemd services.
we plotted our systemd-analyze graph.That graph attached.please give me any idea to reduce my boot optimization time.
1.we register our application scripts.sh in init.d and symlink to rcS.d scripts and created systemd services.
2.we need to load the driver modules first and then load my wifi application scripts and systemd services?
3.while booting only we need to enable our application scripts in init.d.How to enable in latest sdk rootfs?
4.we removed systemd-services but still we are not reached our boot optimization time.
5.can we any one solved this rootfs boot optimization.please suggest me how to do this.
please find my below logs
