移植命令和庫到海思相關芯片
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
編譯會出現問題：只需進入u-boot目錄
vi include/linux/types.h +154
//typedef u_int32_t uintmax_t;
//typedef int32_t intmax_t;
因為在arm-hisiv300-linux/target/usr/include/stdint.h 已經定已過了
2.安裝fw_printenv工具
到/tools/env目錄中，將編譯好的fw_printenv拷貝到目標機的文件系統中，並通過"ln -s fw_printenv fw_setenv"，創建一個fw_setenv到fw_printenv的軟鏈。
註意可以用：
arm-hisiv300-linux-strip fw_printenv
來去掉相應的符號來減少空間的浪費
3.這個工具還需要一個配置文件，以獲取uboot的ENV區域的位置信息。默認狀態下，請將fw_env.config文件拷貝到目標機的文件系統的/etc目錄下。然後結合uboot配置中定義的ENV區和Linux下mtd分區的情況修改配置文件。具體的修改方法見fw_env.config文件中的說明及/tools/env/README文件。
移植ppp相關：
1: 配置編譯內核
在內核原代碼主目錄下make menuconfig內核加入了ppp,socket 等選項
Device Drivers -> Network device support -> <*> PPP (point-to-point protocol)中，選中所有ppp選項：
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，重新執行make ARCH=arm CROSS_COMPILE=arm-hisiv300-linux- uImage .
將arch/arm/boot/下的uImage下載到開發板上重啟系統。
我的內核設置為：
Device Drivers -> Network device support -> <*> PPP (point-to-point protocol)中，選中所有ppp選項：
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核(推薦)
2、配置
進入ppp/ppp-2.4.5/
有兩個目錄etc.ppp scripts
2.1 修改源代碼scripts目錄下的ppp-on ppp-on-dialer ppp-off
之後復制到/etc/ppp目錄下
並修改執行權限，chmod +x ppp-on ppp-off ppp-on-dialer
2.2 pppd提供認證信息時，可能協商使用PAP或者CHAP認證方式，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 *
之後將它們復制到/etc/ppp目錄下
相應的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、配置內核並編譯，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）
註意：這裏的所有選項一定選為built-in [*]，而不能選為Module [M]，如果選為Module，重新燒制的系統內核裏用modprobe ip_tables 命令將不能找到iptables模塊。上一步還有一點要註意的是IP: Netfilter configuration中的FULL NAT選項一定要選中，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) \
--enable-static --disable-shared --disable-ipv6 --disable-nftables \

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:

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;
