I know that this is a fairly general question, but ...
We have a blackfin booting from serial flash. The romfs is jffs2.
jffs2 debugging verbosity 0
jffs2 write-buffering support selected
verify jffs2 write-buffer reads selected
jffs2 summary support selected
jffs2 xattr support not selected
advanced compression options for jffs2 not selected
We're seeing boot time on the order of 3.5 to 4 seconds, and we're wondering if there are any recommended ways to improve on this.
