Manual Build

Image building need host to ready with all necessary tools ready, refer here

Below are the details of Image build for Tinker RK3288 board. Manual Build


$ git clone git://git.denx.de/u-boot.git
$ cd u-boot
$ make tinker-rk3288_defconfig
$ make


$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
$ cd linux-next
$ make mrproper
$ ARCH=arm make multi_v7_defconfig
$ ARCH=arm make -j 4 LOADADDR=0x02000000 uImage dtbs
$ ARCH=arm make modules -j 4
$ ARCH=arm make modules_install -j 4


It’s easy to build entire system using buildroot and mainline supported Tinker board already. See read this readme.txt for more info.

$ git clone git://git.busybox.net/buildroot
$ cd buildroot
$ make asus_tinker_rk3288_defconfig && make

SD Boot

Create Single partition and Insert the SD on host

$ git clone https://github.com/openedev/rfs-rk3288
$ cp rfs-rk3288/* /media/jagan/rootfs
$ cd /path/to/u-boot
$ ./tools/mkimage -n rk3288 -T rksd -d ./tpl/u-boot-tpl.bin out
$ cat ./spl/u-boot-spl-dtb.bin >> out
$ dd if=out of=/dev/mmcblk0 seek=64
$ dd if=u-boot-dtb.img of=/dev/mmcblk0 seek=16384
$ cp /path/to/linux-next/arch/arm/boot/uImage /media/jagan/rootfs/boot
$ cp /path/to/linux-next/arch/arm/boot/dts/rk3288-tinker.dtb /media/jagan/rootfs/boot
$ sync && $ umount /dev/mmcblk0

Falcon Boot

Build U-Boot, Linux manually from above steps, and create falcon mode partition from, here

Once the partitioning done, copy all images like SD Boot. Configure falcon
