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.
RK3288(upgrade_tool)
To create a suitable image and flash it to the board:
default : with CONFIG_ROCKCHIP_SPL_BACK_TO_BROM
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）
RK3036
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
RK3399
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
PARTITIONS!!
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

Copy zimage, dts and ramdisk to /dev/sdb1

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.
Difference:
<code>label kernel-4.4
