移植命令和库到海思相关芯片

1. 编译fw_printenv工具： 

  make ARCH=arm CROSS_COMPILE=arm-hisiv300-linux- hi3521a_config

  make ARCH=arm CROSS_COMPILE=arm-hisiv300-linux-

make ARCH=arm CROSS_COMPILE=arm-hisiv300-linux- env

编译会出现问题：只需进入u-boot目录

vi include/linux/types.h +154

//typedef u_int32_t                  uintmax_t;

//typedef int32_t                    intmax_t;

因为在arm-hisiv300-linux/target/usr/include/stdint.h 已经定已过了

2.安装fw_printenv工具

到/tools/env目录中，将编译好的fw_printenv拷贝到目标机的文件系统中，并通过"ln -s fw_printenv fw_setenv"，创建一个fw_setenv到fw_printenv的软链。

注意可以用：

arm-hisiv300-linux-strip  fw_printenv  

来去掉相应的符号来减少空间的浪费

3.这个工具还需要一个配置文件，以获取uboot的ENV区域的位置信息。默认状态下，请将fw_env.config文件拷贝到目标机的文件系统的/etc目录下。然后结合uboot配置中定义的ENV区和Linux下mtd分区的情况修改配置文件。具体的修改方法见fw_env.config文件中的说明及/tools/env/README文件。

移植ppp相关：

1: 配置编译内核

在内核原代码主目录下make menuconfig内核加入了ppp,socket 等选项

 

Device Drivers -> Network device support  -> <*> PPP (point-to-point protocol)中，选中所有ppp选项：

Device Drivers ->

    Network Device Support->

       <*> PPP (point-to-point protocol) support

       [*]   PPP multilink support

       <*> PPP support for async serial ports

       <*> PPP support for sync tty ports

       <*> SLIP (serial line) support

       [*]   CSLIP compressed headers

Device Drivers -> Network device support -> <*> Universal TUN/TAP device driver support

退出，保存配置，重新执行make ARCH=arm CROSS_COMPILE=arm-hisiv300-linux- uImage .

将arch/arm/boot/下的uImage下载到开发板上重启系统。

 

我的内核设置为：

Device Drivers -> Network device support  -> <*> PPP (point-to-point protocol)中，选中所有ppp选项：

Device Drivers ->

    Network Device Support->

       <M> PPP (point-to-point protocol) support

       [*]   PPP multilink support

       <M> PPP support for async serial ports

       <M> PPP support for sync tty ports

       <M> SLIP (serial line) support

       [*]   CSLIP compressed headers

Device Drivers -> Network device support -> <M> Universal TUN/TAP device driver support

需要将未安装的模块使用insmod命令加载.ko。  也可以直接向上面那样,编译出具有这些功能的内核(推荐)

2、配置

进入ppp/ppp-2.4.5/

有两个目录etc.ppp scripts

2.1 修改源代码scripts目录下的ppp-on ppp-on-dialer ppp-off

     之后复制到/etc/ppp目录下

     并修改执行权限，chmod +x ppp-on ppp-off ppp-on-dialer

2.2 pppd提供认证信息时，可能协商使用PAP或者CHAP认证方式，所以需要修改源代码etc.ppp目录下的pap-secrets和chap-secrets，

 在pap-secrets添加需要的用户名和密码

 card * card * 

 在chap-secrets添加需要的用户名和口令

 card * card *

 之后将它们复制到/etc/ppp目录下

相应的maefile如下：

TOOLS_TOP_DIR ?= $(shell pwd)

TOOL_TAR_BALL := ppp-2.4.5.tar.gz

TOOL_NAME :=ppp-2.4.5

TOOL_BIN := bin

OSDRV_CROSS ?= arm-hisiv300-linux

OSDRV_CROSS_CFLAGS ?= -mcpu=cortex-a7 -mfloat-abi=softfp -mfpu=neon-vfpv4

subdir := pppd  pppdump  pppstats chat

all:

-rm $(TOOLS_TOP_DIR)/$(TOOL_NAME) -rf;

tar -xvf $(TOOL_TAR_BALL);

mkdir -p $(TOOLS_TOP_DIR)/$(TOOL_NAME)/$(TOOL_BIN)/;

mkdir -p $(TOOLS_TOP_DIR)/$(TOOL_BIN)/;

pushd $(TOOLS_TOP_DIR)/$(TOOL_NAME)/; /

./configure   > /dev/null; /

make CC=arm-hisiv300-linux-gcc  -j 20 > /dev/null; /

for d in $(subdir); do(arm-hisiv300-linux-strip $$d/$$d;cp $$d/$$d $(TOOLS_TOP_DIR)/$(TOOL_BIN) -rf); done 

popd

.PHONY: clean

-pushd $(TOOLS_TOP_DIR)/$(TOOL_NAME)/ &&/

make -C $(TOOLS_TOP_DIR)/$(TOOL_NAME)/ clean && /

popd

.PHONY: distclean

distclean:

-rm $(TOOLS_TOP_DIR)/$(TOOL_NAME) -rf;

-rm $(TOOLS_TOP_DIR)/$(TOOL_BIN) -rf;

iptables的配置：

一、配置内核并编译，支持netfilter

cd linux-3.10.y

make ARCH=arm CROSS_COMPILE=arm-hisiv300-linux- menuconfig

[*] Networking support  —>

       Networking options  —>

              [*] Network packet filtering framework (Netfilter)  —>

                     Core Netfilter Configuration  —>（全部选上）

                     IP: Netfilter Configuration  —> （全部选上）

注意：这里的所有选项一定选为built-in [*]，而不能选为Module [M]，如果选为Module，重新烧制的系统内核里用modprobe ip_tables 命令将不能找到iptables模块。上一步还有一点要注意的是IP: Netfilter configuration中的FULL NAT选项一定要选中，否则将不能使用 iptables -t nat命令

makefile修改入下：

TOOLS_TOP_DIR ?= $(shell pwd)

TOOL_TAR_BALL := iptables-1.6.1.tar.bz2

TOOL_NAME :=iptables-1.6.1

TOOL_BIN := install

OSDRV_CROSS ?= arm-hisiv300-linux

OSDRV_CROSS_CFLAGS ?= -mcpu=cortex-a7 -mfloat-abi=softfp -mfpu=neon-vfpv4

all:

-rm $(TOOLS_TOP_DIR)/$(TOOL_NAME) -rf;

tar -xvf $(TOOL_TAR_BALL);

mkdir -p $(TOOLS_TOP_DIR)/$(TOOL_BIN)/;

pushd $(TOOLS_TOP_DIR)/$(TOOL_NAME)/; /

./configure  –host=$(OSDRV_CROSS) –prefix=$(TOOLS_TOP_DIR)/$(TOOL_BIN) /

  –enable-static –disable-shared  –disable-ipv6  –disable-nftables  /

–disable-largefile > /dev/null; /

make -j 20 > /dev/null; /

make install  > /dev/null; /

arm-hisiv300-linux-strip $(TOOLS_TOP_DIR)/$(TOOL_BIN)/sbin/xtables-multi

rm -rf $(TOOLS_TOP_DIR)/$(TOOL_BIN)/sbin/iptables*

mv $(TOOLS_TOP_DIR)/$(TOOL_BIN)/sbin/xtables-multi $(TOOLS_TOP_DIR)/$(TOOL_BIN)/sbin/iptables

popd

.PHONY: clean

clean:

-pushd $(TOOLS_TOP_DIR)/$(TOOL_NAME)/ &&/

make -C $(TOOLS_TOP_DIR)/$(TOOL_NAME)/ clean && /

popd

 

.PHONY: distclean

distclean:

-rm $(TOOLS_TOP_DIR)/$(TOOL_NAME) -rf;

-rm $(TOOLS_TOP_DIR)/$(TOOL_BIN) -rf;

 

移植e2fsprogs相关

TOOLS_TOP_DIR ?= $(shell pwd)

TOOL_TAR_BALL := e2fsprogs-1.41.11.tar.gz

TOOL_NAME := e2fsprogs-1.41.11

TOOL_BIN := bin

OSDRV_CROSS ?= arm-hisiv300-linux

OSDRV_CROSS_CFLAGS ?= -mcpu=cortex-a7 -mfloat-abi=softfp -mfpu=neon-vfpv4

 

all:

-rm $(TOOLS_TOP_DIR)/$(TOOL_NAME) -rf;

tar -xzf $(TOOL_TAR_BALL);

mkdir -p $(TOOLS_TOP_DIR)/$(TOOL_NAME)/$(TOOL_BIN)/;

mkdir -p $(TOOLS_TOP_DIR)/$(TOOL_BIN)/;

pushd $(TOOLS_TOP_DIR)/$(TOOL_NAME)/; /

./configure –host=$(OSDRV_CROSS) CFLAGS="$(OSDRV_CROSS_CFLAGS)" /

LDFLAGS="$(OSDRV_CROSS_CFLAGS)" –prefix=$(TOOLS_TOP_DIR)/$(TOOL_NAME)/$(TOOL_BIN) /

–disable-tls > /dev/null; /

make -j 20 > /dev/null; /

make install  > /dev/null; /

cp $(TOOL_BIN)/sbin/mkfs.ext2 $(TOOLS_TOP_DIR)/$(TOOL_BIN) -rf; /

cp $(TOOL_BIN)/sbin/mkfs.ext3 $(TOOLS_TOP_DIR)/$(TOOL_BIN) -rf; /

cp $(TOOL_BIN)/sbin/mkfs.ext4 $(TOOLS_TOP_DIR)/$(TOOL_BIN) -rf; /

cp $(TOOL_BIN)/sbin/mke2fs $(TOOLS_TOP_DIR)/$(TOOL_BIN) -rf; /

popd

.PHONY: clean

 

-pushd $(TOOLS_TOP_DIR)/$(TOOL_NAME)/ &&/

make -C $(TOOLS_TOP_DIR)/$(TOOL_NAME)/ clean && /

popd

 

.PHONY: distclean

distclean:

-rm $(TOOLS_TOP_DIR)/$(TOOL_NAME) -rf;

-rm $(TOOLS_TOP_DIR)/$(TOOL_BIN) -rf;

 顶层makefile如下：

subdir:=ppp iptables e2fsprogs udev  reg-tools bftpd

TOP_DIR:=$(shell pwd)

TOP_BIN:=bin

TOP_ETC:=etc

all:

mkdir -p $(TOP_DIR)/$(TOP_BIN) 

mkdir -p $(TOP_DIR)/$(TOP_ETC) 

for d in $(subdir); do (make -C $$d); done 

cp creat_softlink.sh $(TOP_DIR)/$(TOP_BIN) && chmod a+x $(TOP_DIR)/$(TOP_BIN)/creat_softlink.sh

for d in $(subdir); do (cp $$d/$(TOP_BIN)/* $(TOP_DIR)/$(TOP_BIN) -rf); done 

for d in $(subdir); do (cp $$d/$(TOP_ETC)/* $(TOP_DIR)/$(TOP_ETC) -rf); done 

.PHONY:clean distclean

clean:

for d in $(subdir); do (make clean -C $$d); done 

distclean:

-rm $(shell pwd)/bin -rf;

-rm $(shell pwd)/etc -rf;

for d in $(subdir); do (make distclean -C $$d); done
