Core 3568J 移植openHarmony Release3.1出现的问题

ChikoHu

1，首先参考了“https://dev.t-firefly.com/thread-117090-1-1.html”，按照这个思路及作者的意见，运行内核一直出错。错误信息如下

说是缺少了ramdisk.img文件。

2，更换思路，将linux sdk的关于Core rk3568J移植到openHarmony 3.1 Release里面，以下是移植内容
2.1 先编译润和的rk3568
2.1.1 修改配置ramdisk

1. productdefine/common/device/rk3568.json
   
2. 
   
3. "enable_ramdisk": false,

复制代码

2.1.1 编译
./build.sh --product-name rk3568 –ccache
镜像文件生成目录：out/rk3568/packages/phone/images

2.2 拷贝Core rk3568J 相关文件
     依赖的设备树
2.3 修改make-ohos.sh（out/kernel/src_tmp/linux-5.10/make-ohos.sh）
     添加编译支持 AIOJ-RK3568

2.4 编译（可以考虑同时更换开机画面）

1. ./make-ohos.sh AIOJ-RK3568

复制代码

重新生成 boot_linu.img和resource.img


3.烧录
3.1 拷贝镜像文件:out/rk3568/packages/phone/images/目录下
MiniLoaderAll.bin,parameter.txt,system.img,uboot.img,userdata.img,vendor.img
3.2 拷贝内核文件:out/kernel/src_tmp/linux-5.10/目录下
boot_linu.img，resource.img
3.3 使用烧录工具进行烧录

4，启动
启动没有问题，看着也挺多错误的。

1. <blockquote>[ 7572.608901] audit: type=1400 audit(1501931174.927:2163): avc:  denied  { ioctl } for  pid=1611 comm="dmesg" path="/dev/console" dev="tmpfs" ino=167 ioctlcmd=0x5413 scontext=u:r:sh:s0 tcontext=u:object_1

5，问题描述（希望大侠帮忙看看怎么解决）
5.1 HDMI无法显示
从日志上，从DRM 到 HDMI 好像没啥问题，但是就是显示不出来，偶尔会显示出开机logo和进入，但是大部分还是无法显示界面。
HDMI的I2C正常的，不知道问题出在哪里，我加了一些日志

5.2 网络有权限问题
网络正常，能用PC ping通开发板，但是开发板无法ping的PC，看错误是权限问题，这个不知道怎么解决， 有大侠了解吗
5.2.1 ipconfig -a 显示正常
5.2.2 设置ip
ifconfig eth0 192.168.50.249 netmask 255.255.255.0

1. # ifconfig eth1 192.168.50.249 netmask 192.168.50.205

查看ip 已经设置成功

5.2.4 ping 就会出现如下错误，有权限问题，这就完全不懂了。

1. # ping 192.168.50.205

不知道这种信息，需要怎么处理，不太懂这方面。


5.3 其它的功能暂时还没去弄，这几天一直在处理上面2个问题。也一直没解决

AIOJ-RK3568这个板子最近会开始支持的

AIOJ-RK3568这个板子这两天会支持的

感觉整个openHarmony运行起来，有很多权限问题，是不是跟selinux有关？

还要研究下，我这边确实复现了同样的问题，HDMI显示问题，ping权限问题。但是在hdc_std上是可以正常ping的，这个要研究下。
