my embeded board has installed two flash devices, when i compile my
kernel I selected all drivers refered to flash, but now I boot into
embeded system, and can't find flash devices, as my previous plan, I
wouldd manipulated flash such as format, fdisk, burned kernel image
into it .....etc. so what I shoud do to find the flash DEVICE?
when type: ls /dev/ftl*
sh-2.04# ls -al /dev/ftl*
brw-r--r-- 1 root root 44, 0 Jul 3 2006 /dev/ftla
brw-r--r-- 1 root root 44, 1 Jul 3 2006 /dev/ftla1
brw-r--r-- 1 root root 44, 2 Jul 3 2006 /dev/ftla2
brw-r--r-- 1 root root 44, 3 Jul 3 2006 /dev/ftla3
brw-r--r-- 1 root root 44, 4 Jul 3 2006 /dev/ftla4
brw-r--r-- 1 root root 44, 16 Jul 3 2006 /dev/ftlb
brw-r--r-- 1 root root 44, 17 Jul 3 2006 /dev/ftlb1
brw-r--r-- 1 root root 44, 18 Jul 3 2006 /dev/ftlb2
brw-r--r-- 1 root root 44, 19 Jul 3 2006 /dev/ftlb3

I guess both ftla and ftlb are thoes two flash, but I don't open them.
what's wrong? can anyone tell me how to use flash devices in normal
case? I'm embeded development newbie, please guide me a clue, thank you
very much.
