Well I got this and it works.
I built the module to support ZFS on the BPI-w2 board, these were the steps.
(Ubuntu 16.04)
- Download Kernel source & build cross-compile (PC)
- Download & extract https://github.com/BPI-SINOVOIP/BPI-W2-bsp/archive/refs/heads/master.zip
- ./build.sh (3. Build kernel only.)
- ./build.sh (5.)
- ./build.sh (6.)
- ./build.sh (7. Update local build to SD with BPI Image flashed)
- Copy linux-rtk/ -> SD /root/linux-stable
- Download & extract spl 0.7.5 -> SD /root/spl-0.7.5
- Download & extract zfs 0.7.5 -> SD /root/zfs-0.7.5
Then I installed the SD on the board and I prepared the modules, as follows…
- cd /root/zfs-0.7.5
- ./autogen.sh
- ./configure --prefix=/ --libdir=/lib --includedir=/usr/include --datarootdir=/usr/share --enable-linux-builtin=yes --with-linux=/root/linux-stable --with-linux-obj=/root/linux-stable
- ./copy-builtin /root/linux-stable
- make
- make install
- cd /root/zfs-0.7.5
- Edit META file change CDDL to GPL (Reported: https://github.com/openzfs/zfs/issues/9948)
- ./autogen.sh
- ./configure --prefix=/ --libdir=/lib --includedir=/usr/include --datarootdir=/usr/share --enable-linux-builtin=yes --with-linux=/root/linux-stable --with-linux-obj=/root/linux-stable --with-spl=/root/spl-0.7.5 --with-spl-obj=/root/spl-0.7.5
- ./copy-builtin /root/linux-stable
- make
- make install
Then I copied the directory to the PC (/root/linux-stable), in the directory tree of BPI-W2-bsp. I enabled the SPL and ZFS modules, to finally recompile the kernel.
- ./build.sh (4. kernel configure.) Enable SPL module and ZFS File System module
- ./build.sh (3. Build kernel only.)
- ./build.sh (5.)
- ./build.sh (6.)
- ./build.sh (7. Update local build to SD with BPI Image flashed)
I hope it works for you.
