Compile the fw_printenv tool:

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

There is a problem with the compilation: just go to the u-boot directory

Vi include/linux/types.h + 154,

/ / typedef u_int32_t uintmax_t

/ / typedef int32_t intmax_t

Because it's already over in arm-hisiv300-linux/target/usr/include/stdint.h.

two。 Install fw_printenv tools

In the / tools/env directory, copy the compiled fw_printenv to the target's file system, and create a fw_setenv-to-fw_printenv soft chain through "ln-s fw_printenv fw_setenv".

Note that you can use:

Arm-hisiv300-linux-strip fw_printenv

To remove the corresponding symbols to reduce the waste of space

3. The tool also requires a configuration file to get the location information of the ENV area of the uboot. By default, copy the fw_env.config file to the / etc directory of the target's file system. Then modify the configuration file according to the ENV area defined in the uboot configuration and the mtd partition under Linux. For the specific modification method, see the instructions in the fw_env.config file and / tools/env/README file.

Related to migrating ppp:

1: configure the compiled kernel

Ppp,socket and other options are added to the make menuconfig kernel under the main directory of the original kernel code.

In Device Drivers-> Network device support-> PPP (point-to-point protocol), select all ppp options:

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

Exit, save the configuration, and re-execute make ARCH=arm CROSS_COMPILE=arm-hisiv300-linux- uImage.

Download the uImage under arch/arm/boot/ to the development board to restart the system.

My kernel is set to:

In Device Drivers-> Network device support-> PPP (point-to-point protocol), select all ppp options:

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

Uninstalled modules need to be loaded using the insmod command. Ko. You can also compile a kernel with these functions directly as above (recommended)

2. Configuration

Enter ppp/ppp-2.4.5/

There are two directories etc.ppp scripts

2.1 modify the ppp-on ppp-on-dialer ppp-off under the source code scripts directory

Then copy it to the / etc/ppp directory

And modify the execution permission, chmod + x ppp-on ppp-off ppp-on-dialer

2.2 when pppd provides authentication information, it may be negotiated to use PAP or CHAP authentication, so you need to modify the pap-secrets and chap-secrets under the source code etc.ppp directory.

Add the required username and password in pap-secrets

Card * card *

Add the required username and password in chap-secrets

Card * card *

Then copy them to the / etc/ppp directory

The corresponding maefile is as follows:

TOOLS_TOP_DIR? = $(shell pwd)

Configuration of iptables:

Configure the kernel and compile it to support 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-- > (select all)

IP: Netfilter Configuration-- > (all selected)

Note: all options here must be built-in [*], not Module [M]. If Module is selected, the iptables module will not be found in the refired system kernel with the modprobe ip_tables command. Another thing to note in the previous step is that the FULL NAT option in IP: Netfilter configuration must be selected, otherwise you will not be able to use the iptables-t nat command
