=== '''extend rootfs partition''' ===
<br>
After After the system running operating card is prepared, the rootfs partition of the file system rootfs partition should be expanded immediately. This will greatly improve the performance of the system performance and avoid various tedious complicated problems caused by insufficient space.<br> We <br>We can use the system's built-in script resize_rootfs.sh to expand the capacity after entering the system.:

=== '''Test method of PCIE interface''' ===<br> When using the PCIE interface, it should be noted that if the PCIE interface is used, the USB2.0 interface cannot be used. If used at the same time, it will cause a system error.<br>Currently, only the rtl8822be PCIE driver is integrated in the linux3.10 kernel. The drivers for other PCIE devices have not been adapted for the time being, and other versions of the kernel cannot currently use the PCIE function.
