HI3518EV200初体验

Chap1 SDK初探

step1.1 解压到自己的工作目录
进入解压后的目录Hi3518E_SDK_V1.0.4.0可以看到4个文件(linux下一切皆文件?)

package  scripts  sdk.cleanup  sdk.unpack

目录说明:
package     :存放SDK各种压缩包的目录
scripts     :存放shell脚本的目录
sdk.cleanup : SDK清理脚本,运行后整个目录将恢复到解压后的初始状态,请注意自己的修改内容,谨慎运行
sdk.unpack  : SDK展开脚本,用以快速展开基本的SDK包

step1.2 运行./sdk.unpack解压SDK包

期间可能会有报错:
./sdk.unpack: 2: ./sdk.unpack: source: not found
./sdk.unpack: 4: ./sdk.unpack: ECHO: not found
./sdk.unpack: 6: ./sdk.unpack: WARN: not found
./sdk.unpack: 7: ./sdk.unpack: WARN: not found
./sdk.unpack: 8: ./sdk.unpack: ECHO: not found
./sdk.unpack: 20: ./sdk.unpack: ECHO: not found
./sdk.unpack: 22: ./sdk.unpack: run_command_progress_float: not found
./sdk.unpack: 24: ./sdk.unpack: ECHO: not found
./sdk.unpack: 26: ./sdk.unpack: run_command_progress_float: not found
./sdk.unpack: 37: ./sdk.unpack: ECHO: not found
./sdk.unpack: 39: ./sdk.unpack: run_command_progress_float: not found
./sdk.unpack: 42: ./sdk.unpack: ECHO: not found
./sdk.unpack: 44: ./sdk.unpack: run_command_progress_float: not found

解决方法:修改系统默认shell为bash
sudo dpkg-reconfigure dash
选择:否/no,重新运行脚本即可

运行后可以看到当前目录下的文件结构: 

drv  mpp  osdrv  package  scripts  sdk.cleanup  sdk.unpack

新增目录说明:
drv    :driver相关
mpp    :媒体处理软件平台(Media Process Platform)相关
osdrv  :操作系统及相关驱动

Chap2.SDK整体编译

step2.1 编译链的安装与选择
    040SDK包中提供两种编译工具链 arm-hisiv300-linux 和 arm-hisiv400-linux在osdrv/opensource/toolchain目录下,其中 arm-hisiv300-linux 为基于 uclibc 的工具链, arm-hisiv400-linux 为基于 glibc 的工具链。请注意uboot,kernel,rootfs,和我们的app要统一使用某一个交叉编译链编译,不要两个编译链混用,否则系统运行的时候可能出现奇奇怪怪的错误,安装方法如下(注意,需要有sudo权限或者root权限):
    1)安装v300编译链:
       进入arm-hisiv300-linux目录,然后运行./cross.install即可。
    2)安装v400编译链:
       进入arm-hisiv400-linux目录,运行chmod +x cross.install,然后运行./cross.install即可。
    3)生效环境变量:
       编辑 /etc/environment,在""内加入[ /opt/hisi-linux/x86-arm/arm-hisiv300-linux/target/bin/:/opt/hisi-linux/x86-arm/arm-hisiv400-linux/target/bin ](注意用:分隔),然后souce /etc/environment即可
    4)编译链的选取:
       由于单板资源有限,而ulibc比glibc要小很多,所以后续正常情况下选择arm-hisiv300-linux作为我的编译链

step2.2 整体编译
    进入目录,make OSDRV_CROSS=arm-hisiv300-linux CHIP=hi3518ev200 all,整体编译。编译期间可能会遇到若干错误,关键字摘录如下:
    错误1:

collect2: error: ld returned 1 exit status

    错误6:其他
step2.3 错误分析及解决
    产生这些错误的原因在于我们的环境搭建不完全,无论是pc还是交叉编译链。处理方法有如下两种。
    Action1.  修改顶层Makefile:删除目标 all的依赖,hipctools hiboardtools,这样一来不再编译这些工具,可以自己安装代替,同时也需要修改Makefile中使用这些工具的地方,如:

pushd $(OSDRV_DIR)/pub/bin/pc;./mkfs.jffs2 -d $(OSDRV_DIR)/pub/$(PUB_ROOTFS) -l -e 0x40000 -o $(OSDRV_DIR)/pub/$(PUB_IMAGE)/$(JFFS2_IMAGE_BIN_256K);popd
pushd $(OSDRV_DIR)/pub/bin/pc;./mkfs.jffs2 -d $(OSDRV_DIR)/pub/$(PUB_ROOTFS) -l -e 0x20000 -o $(OSDRV_DIR)/pub/$(PUB_IMAGE)/$(JFFS2_IMAGE_BIN_128K);popd
pushd $(OSDRV_DIR)/pub/bin/pc;./mkfs.jffs2 -d $(OSDRV_DIR)/pub/$(PUB_ROOTFS) -l -e 0x10000 -o $(OSDRV_DIR)/pub/$(PUB_IMAGE)/$(JFFS2_IMAGE_BIN_64K);popd
pushd $(OSDRV_DIR)/pub/bin/pc;./mkfs.ubifs -d $(OSDRV_DIR)/pub/$(PUB_ROOTFS) -m 2KiB -e 126976 -o ./$(UBIFS_UBI_IMAGE_BIN) -c 256 -F;popd
pushd $(OSDRV_DIR)/pub/bin/pc;./ubinize -m 2KiB -p 128KiB -o $(OSDRV_DIR)/pub/$(PUB_IMAGE)/$(UBIFS_IMAGE_BIN) ubi.cfg;popd
pushd $(OSDRV_DIR)/pub/bin/pc;rm ./$(UBIFS_UBI_IMAGE_BIN) ubi.cfg -rf;popd

   Action2: 给SDK打补丁。针对以上错误,我给SDK做了一份补丁,补丁脚本内容如下:

#!/bin/bash

#Author:	Lucas
#Email:		[email protected]
#QQ:		2302457646
#Notice:
#	1. you must have runned the script [sdk.unpack] to unpack the sdk
#	2. you must have runned the script [cross.install.v300] or others to install the compiler
#	3. you may should adapt for another compiler firstly, 
#		this patch is for arm-hisiv300-linux, others may be will get some errors.

   运行该补丁后再编译即可。补丁内容不再赘述。

step2.4  再编译
    打完补丁后,运行 make OSDRV_CROSS=arm-hisiv300-linux CHIP=hi3518ev200 nproc=$(($(nproc)-1)) all,耐心等待几分钟后,提示编译成功HI3518EV200初体验_第1张图片

结尾:
    经过一顿疯狂的操作后,SDK编译成功,HI3518E的开发环境算是搭建成功啦,后续可以开启海思的基本学习了,如有问题或错漏,欢迎大家留言指出,同时补丁脚本中也包含联系方式?
