Revision as of 07:59, 8 September 2023

1 Android系统的使用

1.1 Android7 下使用4G模块EC20

1.1.1 连接方法

连接时，需要通过USB to miniPCIe转接板转接EC20，再连接到主板的USB Host端口，以T2为例，如下图所示：
T2-4G-EC20.jpg
连接后无需额外的配置，启动Android后就可以使用4G上网了，跟Android手机类拟。


替换下面路径下的 logo.bmp: 

/opt/FriendlyARM/smart4418/android/device/friendlyelec/nanopi3/boot/logo.bmp
/opt/FriendlyARM/smart4418/android/device/friendlyelec/nanopi2/boot/logo.bmp

重新编译 Android 源代码。

1.3 使用fastboot命令烧写android固件

上电时在串口终端敲回车进入uboot命令行模式，然后输入以下命令： 

fastboot 0

For S5P4418, PC端可使用以下命令来更新emmc: 

fastboot flash partmap partmap.txt
fastboot flash 2ndboot bl1-mmcboot.bin
fastboot flash fip-loader loader-mmc.img
fastboot flash fip-secure bl_mon.img
fastboot flash fip-nonsecure bootloader.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash cache cache.img
fastboot flash userdata userdata.img

For S5P6818, PC端可使用以下命令来更新emmc: 

fastboot flash partmap partmap.txt
fastboot flash 2ndboot bl1-mmcboot.bin
fastboot flash fip-loader fip-loader.img 
fastboot flash fip-secure fip-secure.img 
fastboot flash fip-nonsecure fip-nonsecure.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash cache cache.img
fastboot flash userdata userdata.img

1.4 Android证书

Android 5 我们缺省采用的是自己生成的证书，位于: 

  vendor/friendly-arm/nanopi3/security/

Android 7 缺省采用的是: 

  build/target/product/security/

1.5 Android7只连接HDMI的情况下性能优化

1.5.1 背景说明

默认情况下，驱动会初始化两个framebuffer，分别用于主显示LCD和HDMI，如果项目需求只需要使用HDMI，不需要用LCD，则可以根据本章节的步骤进行修改，修改后会将HDMI设置为主显示，这样驱动只会初始化一个framebuffer，节约资源，对UI性能和开机速度会有相应的提升。
本章节内容仅适用于 S5P6818 Android7, S5P4418修改方法类拟，只是需要调整一下相应的文件。

1.5.2 修改内核

需要修改内核dts，禁止dp_drm_lvds节点, 如下所示: 

--- a/arch/arm64/boot/dts/nexell/s5p6818-nanopi3-common.dtsi
+++ b/arch/arm64/boot/dts/nexell/s5p6818-nanopi3-common.dtsi

+       status = "disabled";
 
        display-timing {
                clock-frequency = <50000000>;

编译后将获得新的 arch/arm64/boot/dts/nexell/s5p6818-nanopi3-rev*.dtb。
测试阶段可直接通过adb 更新到板子，命令如下: 

adb root; adb wait-for-device; adb shell mkdir /storage/sdcard1/; adb
shell mount -t ext4 /dev/block/mmcblk0p1 /storage/sdcard1/
adb push arch/arm64/boot/dts/nexell/s5p6818-nanopi3-rev*.dtb /storage/sdcard1/

完整的固件则需要替换android7源代码目录 device/friendlyelec/nanopi3/boot 下的文件

1.5.3 修改env.conf

修改 device/friendlyelec/nanopi3/boot/env.conf 增加一行: 

lcdtype     HDMI1080P60

此模式需要与android7启动后探测到的模式相同，否则会导致长时的黑屏状态，甚至无显示输出, 或者进入uboot命令行环境手工设置: 

setenv lcdtype HDMI1080P60; saveenv; reset

1.5.4 修改system.prop

修改android7中 device/friendlyelec/nanopi3/system.prop 

ro.sf.lcd_density=240

或其它自己认为更合适的值, 也可串口或adb环境下，wm density 240 来调整观察效果是否合适。

1.5.5 编译Android

根据wiki说明编译android 7并测试，遇到异常则请仔细检查前面的步骤
