Re: [Gumstix-users] Mount root_fs_arm over nfs

[Craig H. <cr...@gu...>]

I don't think you can mount a JFFS2 filesystem from anything other  
than a physical flash memory device -- in other words, no loopback.   
Two easy solutions here though:

1. Mount buildroot/build_arm_nofpu/root/ via NFS (that is the  
directory from which the root_fs_arm gets built)
2. Create root_fs_arm with some other filesystem instead of JFFS2 --  
change the "jffs2root" in the top-level Makefile to ext2root or  
cramfsroot and then you should be able to to the loopback mount, if  
you want to go that route for some reason.
