Problem description

Font error message on boot, unable to start system

Solution (Linux host +windows virtual machine +USB download)

2. The method of using virtual machine to allocate USB (note: If the serial port is assigned, there will be stm_writememory error, unable to download normally, the reason is unknown. ）

   Configure VBox to identify USB devices, method source: http://xuantan.iteye.com/blog/1130808

   A. Download the VirtualBox 4.0.10 Oracle VM virtualbox Extension Pack package and install it on the Http://www.virtualbox.org/wiki/Downloads website.

   B. sudo/usr/sbin/usermod-g vboxusers-a ' logname ' #将当前用户添加到vboxusers用户组中

   C. cat/etc/group |grep vboxusers #查看vboxusers的ID, the results are similar to Vboxusers:x:108:diefrom, where 108 is the ID

   D. sudo vim/etc/fstab #编辑/etc/fstab file allows vboxusers to read and write permissions to Usbfs

   Add None/proc/bus/usb usbfs devgid=108,devmode=664 0 0 #这里108为第c步中查询的vboxusers ID at the end

4. Configure the environment under Windows

   Mounting drive (with disc on board, no fatigue)

   Install xcom download software (with CD-ROM, no fatigue)
