Hi,
Somebody in the thread at some point said:
In OE we're no longer using the u-boot uncompressor, but use the
one built in in the kernel, which is way faster.
Wah thanks Mickey, I'll change over... that explains it.
Yep chopped decompression down to ~1s... great...
Good.
It's ~18s from power -> rootfs mounted and init running now... that
includes putting the splash up but with loglevel=0 so there are no boot
messages on the LCM.
If we set init=/bin/sh on the kernel commandline, we can actually meet
this 20s boot time target... kinda....
Well, 20s is almost insanely tough. My N810 takes 40s.
Just to add, as jffs2 is used as root filesytem which by default does
compression .
And while executing an application it does decompression this will
increase application launch time.
To avoid this we should disable jffs2 compression (i think there is an
option to mkfs.jffs2), don't know
how this will be reduce the boot time
