Add Board in U-Boot

1) Create Directory: /board/{VENDOR}/{BRDNAME}

2) Check similar driver? GPIO?

2a) For example, if we want to modify GPIO, create the C src file in /driver/gpio/{MARCH}_gpio.c

2b) In the /drivers/gpio/Makefile, add:
COBJS-$(CONFIG_{MARCH}_GPIO) += {BRDNAME}_gpio.o

2c) Create file: include/configs/{BRDNAME}.h
add #define CONFIG_{BRDNAME}_GPIO

3) CPU

3a) Create configs/{BRDNAME}_defconfig in the /configs directory
CONFIG_{ARCH}=y
CONFIG_TARGET_{BRDNAME}=y

3b) In arch/{ARCH}/Kconfig, add:
config TARGET_{BRDNAME}
    bool "Support {BRDNAME}"
    select CPU_{MARCH}

3c) In arch/{ARCH}/Kconfig, add:
source "board/{VENDOR}/{BRDNAME}/Kconfig"

4) Place relevant src files in
/board/{VENDOR}/{BRDNAME}

5) Add your Device in boards.cfg

6) Add Kconfig file:
if TARGET_{BRDNAME}

config SYS_BOARD
    default "{BRDNAME}"

config SYS_VENDOR
    default "{VENDOR}"

config SYS_SOC
    default "{ARCH}"

config SYS_CONFIG_NAME
    default "{BRDNAME}"

endif

  sudo apt-get install exfat-fuse exfat-utils

List the disk

  fdisk -l

Format:

  mkfs.exfat -n LABEL /dev/sdXn

  fsck.exfat /dev/sdXn

Install flash plugin

apt-get install flashplugin-nonfree

install acrobat reader using makepkg

$wget https://aur.archlinux.org/packages/ac/acroread/acroread.tar.gz

$tar -xvzf acroread.tar.gz

$cd acroread

$makepkg -s

$sudo pacman -U *.pkg.tar.xz

if dependence not found - lib32-gtk2..etc...

enable the multilab section in /etc/pacman.cong

------------------------------------------------------------------------------------------------------

To use the multilib repository, uncomment the [multilib] section in /etc/pacman.conf:

[multilib]
Include = /etc/pacman.d/mirrorlist

You will then need to update the package list by running pacman with the -Sy switch.

Note:

If the system has the base-devel package group installed, users must replace the [extra] versions with the [mutlilib] versions as shown below.
gcc-multilib is capable of building 32-bit and 64-bit code. You can safely install multilib-devel to replace the packages shown below, but you still need base-devel for the other packages it includes. See https://bbs.archlinux.org/viewtopic.php?id=102828 for more information.

# pacman -S gcc-multilib

Important:
Even I do the above operation,
I still miss the lib32-pangox-compat dependency,
I manually build above library (extract, config, make, make install) and then delete the pangox-compat dependency in the PKGBUILD flag,
and it can normally run now... :(
