Fig. 2 is mirror image and subregion distribution map.
Specific implementation mode
Technical scheme of the present invention is described in detail with reference to the accompanying drawings and examples.
The embedded Linux system of the overwhelming majority can be transferred through SD card startup now, but due to the access speed of SD card
Slower and pluggable characteristic so that final linux system does not operate in SD card generally, but operates in pcb board
On solid-state memory on.The consequence done so is again so that the refreshing of linux system is inconvenient.It through the invention can be by brush machine
In the mirror image programming to SD card of program and brush machine, it is on the solid-state memory on pcb board to refresh by starting from SD card
System software so that the operation of brush machine greatly simplifies.
