Boot from eMMC

 To get tool and firmware


Flash to the board by USB

In order to flash by USB,you must get your board into ROM boot mode, either by erasing
your MMC or holding the maskrom button when you boot the board.



To create a suitable image and flash it to the board:

tools/mkimage -n rk3288 -T rksd -d spl/u-boot-spl-dtb.bin out<br/> cat u-boot-dtb.bin >> out<br/> sudo upgrade_tool db  ../rkbin/rk32/RK3288UbootLoader_V2.30.06.bin<br/> sudo upgrade_tool wl 64 out<br/> sudo upgrade_tool rd

others : firefly(Recommend using sd card)



To create a suitable image and flash it to the board:

tools/mkimage -n rk3036 -T rksd -d spl/u-boot-spl-dtb.bin out
cat u-boot-dtb.bin >> out
sudo upgrade_tool db  ../rkbin/rk30/RK3036MiniLoaderAll_V2.19.bin
sudo upgrade_tool wl 64 out
sudo upgrade_tool rd


cd ..
./rkbin/tools/trust_merger ./rkbin/tools/RK3399TRUST.ini
cd uboot

../rkbin/tools/loaderimage --pack --uboot u-boot-dtb.bin uboot.img

sudo upgrade_tool UL   ../rkbin/rk33/RK3399MiniLoaderAll_V1.05.bin
sudo upgrade_tool DI uboot uboot.img  ../rkbin/tools/rk3399_parameter.txt 
sudo upgrade_tool DI trust ../trust.img  ../rkbin/tools/rk3399_parameter.txt
sudo upgrade_tool rd


 To flash kernel and rootfs

Enter into the uboot and issue the following command on uboot: (otg should be connected)

gpt write mmc 0 $partitions
ums 0 mmc 0

Now the board will act as an USB-drive.
In host: (assuming sdb is ur device)

sudo mkfs.fat /dev/sdb6

Copy zimage and dts file to dev/sdb6

cp arch/arm/boot/zImage /media/chen/9F35-9565/
cp arch/arm/boot/dts/rk3288-fennec.dtb /media/chen/9F35-9565/rk3288-fennec.dtb

Add extlinux/extlinux.conf to dev/sdb6
(Please notice "mmcblk2p7" and "115200n8" is decide on your chip, Please refer to config table)

label kernel-4.4
    kernel /zImage
    fdt /rk3288-fennec.dtb
    append  earlyprintk console=tty1 console=ttyS2,115200n8 rw root=/dev/mmcblk2p7 rootfstype=ext4 init=/sbin/init

To flash rootfs

sudo dd if=linaro-rootfs.img of=/dev/sdb7 conv=notrunc

Boot from SD/TF Card

Creating Image

Follow linux-user-guide to build kernel and U-Boot.
get uboot-spl.img and u-boot-dtb.img

tools/mkimage -n rk3288 -T rksd -d spl/u-boot-spl-dtb.bin uboot-spl.img

build boot.img

sudo dd if=/dev/zero of=boot.img bs=1M count=128
sudo mkfs.fat boot.img
mkdir boot
sudo mount  boot.img boot
sudo cp zImage boot
sudo cp rk3288-fennec.dtb boot
sudo mkdir boot/extlinux
sudo cp extlinux.conf boot/extlinux
sudo umount boot

Download rootfs image and rename it

mv linaro-rootfs.img rootfs.img

Making a SD Card for updating

Download ramdisk source and build.

sh ./mk-initrd.sh

Format SD card

chen@chen-HP-ProDesk-680-G1-TWR:~/work/linaro-alip/ramdisk/update$ sudo gdisk /dev/sdb
GPT fdisk (gdisk) version 0.8.8

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.

Command (? for help): o
This option deletes all partitions and creates a new protective MBR.
Proceed? (Y/N): y

Command (? for help): n
Partition number (1-128, default 1): 1
First sector (34-126613470, default = 2048) or {+-}size{KMGTP}: 8192
Last sector (8192-126613470, default = 126613470) or {+-}size{KMGTP}: 
Current type is 'Linux filesystem'
Hex code or GUID (L to show codes, Enter = 8300): 
Changed type of partition to 'Linux filesystem'

Command (? for help): w

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING

Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/sdc.
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot.
The operation has completed successfully.
sudo umount /dev/sdb1
sudo mkfs.fat /dev/sdb1
tools/mkimage -n rk3288 -T rksd -d spl/u-boot-spl-dtb.bin out&&
sudo dd if=out of=/dev/sdb seek=64&&sudo dd if=u-boot-dtb.img of=/dev/sdb seek=256

Copy zimage, dts and ramdisk to /dev/sdb1

cp arch/arm/boot/zImage /media/chen/9F35-9565/
cp arch/arm/boot/dts/rk3288-fennec.dtb /media/chen/9F35-9565/rk3288-fennec.dtb
cp ../rk-initrd-build/initrd.img /media/chen/9F35-9565/

Add extlinux/extlinux.conf to /dev/sdb1

label kernel-4.4
    kernel /zImage
    fdt /rk3288-fennec.dtb
    initrd /initrd.img
    append  earlyprintk console=ttyS2,115200n8 rw root=/dev/ram0 rootfstype=ext4 init=/sbin/init ramdisk_size=49152

Copy u-boot-dtb.img uboot-spl.img boot.img rootfs.img and update.sh to /dev/sdb1

mkdir /media/chen/9F35-9565/update
cp u-boot-dtb.img /media/chen/9F35-9565/update
cp uboot-spl.img /media/chen/9F35-9565/update
cp boot.img /media/chen/9F35-9565/update
cp rootfs.img /media/chen/9F35-9565/update
cp update.sh /media/chen/9F35-9565/update

Updating the board

Boot the board and it will flash image to eMMC


Boot from USB-Disk

Same as boot-from-sdcard, but please note that U-Boot aren't allowed to boot from usb-disk because of restrict of maskrom, only kernel and rootfs can load from USB-Disk.


<code>label kernel-4.4

<code>gpt write usb 0 $partitions
