+# 让100ASK_IMX6ULL支持adb
+
+把adbd_files下的文件，全部复制到开发板根目录：
+
+```shell
+cd adbd_files
+cp * / -rf
+
+chmod +x /usr/bin/adb
+chmod +x /usr/bin/adbd
+chmod +x /usr/bin/usb_config
+```
+
+
+
+Ubuntu上安装adb：
+
+```shell
+sudo apt install adb
+sudo chmod a+x /usr/bin/adb
+sudo chmod a+s /usr/bin/adb
+sudo adb kill-server
+```
+
+
+
+然后就可以在Ubuntu上使用adb操作开发板了：
+
+```shell
+adb devices
+adb push 1.txt /root      # 把Ubuntu的文件放到开发板的/root目录
+adb pull /root/1.txt 2.tx # 把开发板的/root/1.txt下载并改名为2.txt
+adb shell                 # 登录开发板
+```
+
