Python環境之 BPI-M2+ 系統升級

BPI-M2+的ubuntu系統已經有最新的，所以就升級到最新版本上。步驟如下：

下載合適的對應的版本。

Step 1: Start up the computer with the SD card which has been burnt with the Linux images.--首先要燒寫該鏡像到sd卡上。

Step 2: Put the images which you'd like to burn to the EMMC Storage to the USB drive.--其次要把該鏡像放到U盤上，用來燒寫到emmc上。

Step 3: Run "fdisk -l" command line on your BPI-M2+ and you can see the EMMC path as " /dev/mmcblk1"

sudo fdisk -l

Step 4:Switch to the path of images, and run the command.

sudo dd if= xxx.img of=/dev/mmcblk1 bs=10MB

xxx.img is your image file name

這個地方，要到U盤掛在的地方，我的板子掛在在media\pi\下。

Step 5:When finish burning, remove the SD card, and restart the BPI-M2+

Step 6:Check if the system starts normally on the EMMC flash boot.

燒寫之后，wifi和bt可以使用。
