mk802 -- insserv
How to add a service when using dependency-based booting
In Debian releases prior to 6.0, a service could be added with update-rc.d:
update-rc.d mydaemon defaults
Starting with Debian 6.0, the insserv command is used instead, if dependency-based booting is enabled:
insserv mydaemon
Where mydaemon is an executable init script placed in /etc/init.d. insserv will produce no output if everything went OK. Examine the error code in $? if you want to be sure.
Both the old and the new way requires an init script to be present in /etc/init.d. For dependency-based booting, the script needs to be an LSB init script.

MK802 II -- OTG
USB On-The-Go, often abbreviated USB OTG, is a specification that allows USB devices such as digital audio players or mobile phones to act as a host, allowing other USB devices like a USB flash drive, mouse, or keyboard to be attached to them.
Standard USB uses a master/slave architecture.

mk802 -- a10 boot process
brom -> boot0 -> boot1 -> boot.axf -> u-boot -> kernel
A10 boot overview
A10 is a quite 'closed chip'. There is a brom in the chip, which can not be modified. This brom will load program from external storage(nand, mmc), which is called boot0 in allwinner. Brom will check the header of boot0, and get hardware information from boot0. The hardware information is in a config file called sys_config.fex. A pc tools will read the config file, and write the hardware information to the head of boot0. After boot0 is booted up, it will continue to load another loader boot1, boot1 init all other hardware and provides hardware abstracts and services. According to the boot OS, boot1 loads an arm elf program, boot.axf. For booting linux, boot.axf loads the u-boot and jumps to the u-boot. Then u-boot will take over.So, the whole boot process is: brom -> boot0 -> boot1 -> boot.axf -> u-boot -> kernel

AllWinner_A1X
The Allwinner A1X, known under Linux as sunxi, is a family of SoC devices designed by AllWinner Technology Co. Ltd. from Zhuhai, China. Currently the family consists of the A13[1] and the A10.[2] The SoCs incorporate the ARM Cortex-A8 as its main processor[3] and the Mali 400 as the GPU.
The Allwinner A1X is known for its ability to easily boot from an SD card GNU/Linux distributions such as Debian, Ubuntu, and other ARM architecture-capable GNU/Linux distributions. The ability is in addition to the Android OS usually installed on the Flash memory of the device.
Models
Currently the A1X family consists of two models. The A10 (sun4i) is the current full-featured SoC with all the features outlined below. The A13 (sun5i) is a lower power consumption and lower cost version of the A10 which is designed primarily for tablet computers. The A13 does not have HDMI or SATA connections.
