Flash image to target emmc

In order to flash image to target emmc, 

1. Make target  get into rockusb mode;
2. Connect target to Host PC via USB;
3. Write the image to the eMMC with tool command;

• use download boot command to make target init DRAM and run usbplug;

rkdeveloptool db rkxx_loader_vx.xx.bin

• use wl command to write image to target, this step can be repeat for many times;

rkdeveloptool wl 0x40 idbLoader.img
rkdeveloptool wl 0x4000 uboot.img
rkdeveloptool wl 0x8000 boot.img
rkdeveloptool wl 0x40000 rootfs.img

• usb ul command to write idbloader into idb from rockchip loader

rkdeveloptool ul rkxx_loader_vx.xx.bin

NOTE: The ul command is the same operation with below command when using Rockchip miniloader, but using different source.

rkdeveloptool wl 0x40 idbLoader.img

NOTE2: The ul command in rkdeveloptool(ul= wl idbloader) is different with the command in upgrade_tool(ul = db + wl idbloader + rd).

• use gpt command to write gpt table with parameter_gpt.txt

rkdeveloptool gpt parameter_gpt.txt

• use rd comamnd to reset the target after image write complete

rkdeveloptool rd
