[microblaze-uclinux] Jffs2 flash protection

[Guillaume.Gastebois@xxxxxxxxxxxxxxxxxxx]

Hello,

I'm trying to use a jffs2 filesystem
on mtd5 using ml505 ll temac reference design with these commands :

cd /tmp
mkdir J
mkfs.jffs2 -d J -o J.img
erase /dev/mtd5
cp J.img /dev/mtd5
mount -t jffs2 /dev/mtdblock5 /tmp/J

All works fine when I unprotect flash
area in U-boot.

My question is : is there a command
to protect/unprotect Intel flash when petalinux image is launched ?

Regards
