Boot Linux on Vyasa RK3288¶
Build the images here, and setup SD card with Single partition here
bootm¶
Ramdisk¶
Create Single partition and Insert the SD on host and Built the images from Image Build
$ 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=256
$ cd /path/to/linux-next
$ cp arch/arm/boot/uImage /media/jagan/rootfs/boot
$ cp arch/arm/boot/dts/rk3288-vyasa.dtb /media/jagan/rootfs/boot
$ cp arm_ramdisk.image /media/jagan/rootfs
$ sync
$ umount /dev/mmcblk0p1
Close JP4 and Insert the SD card and power-on the board.
