Re: [Gumstix-users] Placing a filesystem on partition 2 of MMC card

Hi Will, Thanks for the hints, but unfortunately I am using buildroot (r1630), not OE. I've searched my entire gumstix-buildroot tree, but there is no *.tar.gz image file being built for the root filesystem, just the rootfs.arm_nofpu.jffs2 file, and I have no idea what a .jffs2 file is or how to turn it into a unix filesystem on my MMC card. Apparently, just placing the .jffs2 file onto the 2nd partition isn't sufficient.
