CS-E9302 rootfs in USB Flash drive

Hi all !

I’m using debian rootfs which is storaged in SD memory card. But the file accessing speed is very slow. are there any way to store rootfs in USB FLASH DISK and boot from it ??

OK!

I tried with command line :

exec -c “console=ttyAM root=/dev/sda1 rootdelay=5”

and boot successfull, now my system seem to be faster than

using SD rootfs

That source file Debian rootfs has used

Thank you for your response
