I want to build UFS module: ufs.ko (in order to mount my FreeNAS (BSD) partition) I followed the instructions in these 2 links http://oz123.github.io/writings/2012-11-26-enable-ufs-write-support-debian/ http://blog.drenet.net/enabling-ufs-rw-support-in-ubuntu-12-04-lts
But it seems BPI-M3 Debian Jessie 8 disabled that module, I cannot compile it.
Any help will be really appreciated.

I can build it successfully with these steps: Download BPI-M3 kernel source code from https://github.com/BPI-SINOVOIP/BPI-M3-bsp by either git clone https://github.com/BPI-SINOVOIP/BPI-M3-bsp.git or download BPI-M3-bsp-master.zip and unzip it mkdir ufs cd ufs move BPI-M3-bsp-master folder into ufs
cp -v /usr/src/linux-headers-3.4.109-sunxi/Module.symvers . cp -v /boot/config-3.4.109-sunxi . cd BPI-M3-bsp-master ./build.sh — choose 1 (actually, it does not matter to choose other option) cp linux-sunxi/.config ~/ufs/ cd linux-sunxi make O=~/ufs prepare — most probably will ask you to run “make mrproper” make mrproper make O=~/ufs prepare — this time, no complain make O=~/ufs outputmakefile make O=~/ufs archprepare make O=~/ufs modules SUBDIRS=scripts make O=~/ufs modules SUBDIRS=fs/ufs ----output like: CC [M] fs/ufs/balloc.o CC [M] fs/ufs/cylinder.o CC [M] fs/ufs/dir.o CC [M] fs/ufs/file.o CC [M] fs/ufs/ialloc.o CC [M] fs/ufs/inode.o CC [M] fs/ufs/namei.o CC [M] fs/ufs/super.o CC [M] fs/ufs/symlink.o CC [M] fs/ufs/truncate.o CC [M] fs/ufs/util.o LD [M] fs/ufs/ufs.o Building modules, stage 2.

cd …/… – back to top folder : ~/ufs sudo modinfo fs/ufs/ufs.ko ---- you will see: filename: /home/jzhang18/ufs/fs/ufs/ufs.ko license: GPL srcversion: 034C8B7C93A761904B8400E depends: vermagic: 3.4.39-BPI-M3-Kernel SMP preempt mod_unload modversions ARMv7 p2v8
When I load ufs.ko, I still have some issue. because even ufs.ko match the kernel version, but each function inside ufs.ko does not match the kernel requirement
The only way to eliminate that issue is – to get exact 3.4.39-BPI-M3-Kernel source code, not BPI-M3-bsp-master. But I don’t know where to get it.
