Re: other filesystems on MMC

Jerome,

We re-formatted our MMC card to ext2.  In addition to editing the 
/etc/fstab , you need to recompile the kernel with ext2 filesystem 
support.  Here are some instruction from the FlockBots project page:

Since the filesystem on the MMC card has changed, you must now compile 
ext2 support into the kernel. Goto 
gumstix-buildroot/build_arm/linux-2.6.11gum and type make ARCH=arm 
CROSS_COMPILE=arm-linux- menuconfig (add DEPMOD=true on Mac OS X) to 
configure the kernel to support ext2. To configure the kernel:
Select File systems
Make Second extended fs support be builtin to the kernel
Exit menuconfig


Also, you should recompile the e2fsck program.  Again, from the 
FlockBots project:

The new filesystem on the MMC can become corrupted if the proper 
shutdown sequence is not followed. To fix any filesystem corruption we 
cross compiled e2fsck from the e2fsprogs package with the following 
configure options:
 #!/bin/tcsh

 setenv CFLAGS "-D__ARM__ -D__uclinux__"
 setenv TEMPHOST arm-linux
 setenv CC ${TEMPHOST}-gcc
 setenv AR ${TEMPHOST}-ar
 setenv RANLIB ${TEMPHOST}-ranlib

 setenv BUILD_GCC ${CC}

 e2fsprogs-1.37/configure --host=${TEMPHOST} --build=yourlocalmachine-OS
The complete package does not build, however the e2fsck binary compiles 
correctly, and is located under e2fsprogs-1.37/build/e2fsck. Copy the 
e2fsck binary to the Gumstix under /usr/local/bin for use as an 
utility.


Hope that helps,
Keith
