If you want a faster /dev/ population, you can use devtmpfs. - Choose the DEVTMPFS option in your kernel config. - mount -t devtmpfs devtmpfs /dev in your script - keep the hotplug mechanism - remove the mdev -s line. For fast boot time : set verify=n in u-boot use uncompressed kernel and initramfs enable timing informations on printk for easier debugging try to get as small as possible kernel and initramfs > i want fast boot right now i did it using jffs2 image and time is about > 13seconds from ubl to linux prompt with all the services up and running. > > does doing alot of insmod and mknod on the jffs2 image affects the life of > the flash? > > regard's > RT > > _______________________________________________ > Davinci-linux-open-source mailing list > Davinci-linux-open-source@linux.davincidsp.com > http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source > _______________________________________________ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
