processor sdk (3.00.00.04)rootfs optimisation.

Other Parts Discussed in Thread: AM3352, TPS65910, WL1271

Hi All,

we are using ti-processor-sdk -3.00.00.04 .we are using tisdk-rootfs.tar.gz .rootfs.tar file is 500MB.

we built with yocto setup build core-image-minimal image.But we got 40MB size.

how to add our own scripts while booting in init script.

In /etc/rcS.d contains only two scripts.But tisdk-rootfs-image contains more than two,what is the difference between tisdk-rootfs and core-image minimal image.

And how to optimize rootfs size and boot time for latest ti-processor sdk.

I want to add my own script at /etc/rcS.d.

we followed below link but we are not getting the output.

can any solved this issue .please give me idea

we mentioned boot logs below please find below logs.
