Hello everyone
I am using a ramdisk image to boot the system its takes around 7secs
to copy the ramdisk image from the flash to the RAM and then takes 3.6
seconds after kernal uncompressing to the linux prompt
Reduce your RAMDISK size. Maybe use two partitions, one that is CRAMFS
and another that is RAMDISK.
I want to know that how to reduce this time of 7seconds.
Also can anyone tell how to update the ramdisk image from the linux
prompt.e.g if i have created a file and now iwant it at the next boot
then how to make this file part of the old ramdisk image
How about booting the system quickly with CRAMFS, with a JFFS2
filesystem that is smaller and a RAM disk to match the JFFS2. At
startup, you can mount the JFFS2 (hidden mount point) and RAM disk, copy
the JFFS2 contents to RAM, then on shutdown, copy it back.
