移植命令和庫(kù)到海思相關(guān)芯片

1. 編譯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

編譯會(huì)出現(xiàn)問(wèn)題：只需進(jìn)入u-boot目錄

vi include/linux/types.h +154

//typedef u_int32_t                  uintmax_t;

//typedef int32_t                    intmax_t;

因?yàn)樵赼rm-hisiv300-linux/target/usr/include/stdint.h 已經(jīng)定已過(guò)了

2.安裝fw_printenv工具

到/tools/env目錄中，將編譯好的fw_printenv拷貝到目標(biāo)機(jī)的文件系統(tǒng)中，并通過(guò)"ln -s fw_printenv fw_setenv"，創(chuàng)建一個(gè)fw_setenv到fw_printenv的軟鏈。

注意可以用：

arm-hisiv300-linux-strip  fw_printenv  

來(lái)去掉相應(yīng)的符號(hào)來(lái)減少空間的浪費(fèi)

3.這個(gè)工具還需要一個(gè)配置文件，以獲取uboot的ENV區(qū)域的位置信息。默認(rèn)狀態(tài)下，請(qǐng)將fw_env.config文件拷貝到目標(biāo)機(jī)的文件系統(tǒng)的/etc目錄下。然后結(jié)合uboot配置中定義的ENV區(qū)和Linux下mtd分區(qū)的情況修改配置文件。具體的修改方法見fw_env.config文件中的說(shuō)明及/tools/env/README文件。

移植ppp相關(guān)：

1: 配置編譯內(nèi)核

在內(nèi)核原代碼主目錄下make menuconfig內(nèi)核加入了ppp,socket 等選項(xiàng)

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

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，重新執(zhí)行make ARCH=arm CROSS_COMPILE=arm-hisiv300-linux- uImage .

將arch/arm/boot/下的uImage下載到開發(fā)板上重啟系統(tǒng)。

我的內(nèi)核設(shè)置為：

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

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

需要將未安裝的模塊使用insmod命令加載.ko。  也可以直接向上面那樣,編譯出具有這些功能的內(nèi)核(推薦)

2、配置

進(jìn)入ppp/ppp-2.4.5/

有兩個(gè)目錄etc.ppp scripts

2.1 修改源代碼scripts目錄下的ppp-on ppp-on-dialer ppp-off

     之后復(fù)制到/etc/ppp目錄下

     并修改執(zhí)行權(quán)限，chmod +x ppp-on ppp-off ppp-on-dialer

2.2 pppd提供認(rèn)證信息時(shí)，可能協(xié)商使用PAP或者CHAP認(rèn)證方式，所以需要修改源代碼etc.ppp目錄下的pap-secrets和chap-secrets，

 在pap-secrets添加需要的用戶名和密碼

 card * card * 

 在chap-secrets添加需要的用戶名和口令

 card * card *

 之后將它們復(fù)制到/etc/ppp目錄下

相應(yīng)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、配置內(nèi)核并編譯，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  --->（全部選上）

                     IP: Netfilter Configuration  ---> （全部選上）

注意：這里的所有選項(xiàng)一定選為built-in [*]，而不能選為Module [M]，如果選為Module，重新燒制的系統(tǒng)內(nèi)核里用modprobe ip_tables 命令將不能找到iptables模塊。上一步還有一點(diǎn)要注意的是IP: Netfilter configuration中的FULL NAT選項(xiàng)一定要選中，否則將不能使用 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) \

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相關(guān)

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/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;

 頂層makefile如下：

TOP_DIR:=$(shell pwd)

TOP_BIN:=bin

TOP_ETC:=etc
