此篇編譯根檔案系統

下載busybox和dropbear，

在busybox目錄下，預設配置並初始化

make ARCH=arm CROSS_COMPILE=arm-xilinx-linux-gnueabi- defconfig

視覺化配置

make ARCH=arm CROSS_COMPILE=arm-xilinx-linux-gnueabi- menuconfig

安裝根檔案系統到指定目錄

make ARCH=arm CROSS_COMPILE=arm-xilinx-linux-gnueabi- install

在dropbear目錄下配置dropbear

/home/fpgadeveloper/Zybo_Demo/XilinxFS/dropbear-0.53.1

1	`./configure --prefix=/home/fpgadeveloper/Zybo_Demo/XilinxFS/RootFS --host=arm-xilinx-linux-gnueabi --disable-zlib CC=arm-xilinx-linux-gnueabi-gcc LDFLAGS="-Wl,--gc-sections"` `CFLAGS="-ffunction-sections -fdata-sections -Os"`

編譯dropbear

make PROGRAMS="dropbear dbclient dropbearkey dropbearconvert scp" MULTI=1 strip

安裝dropbear並建立符號連結

sudo make install

建立軟連線，進入/home/fpgadeveloper/Zybo_Demo/XilinxFS/RootFS/usr/bin

1	`[#23#23:28:47 [email protected] ~/Zybo_Demo/XilinxFS/RootFS/usr/bin]$ln -s ../../sbin/dropbear ./scp`

將交叉編譯庫拷貝到下述目錄

sudo cp ~/SDK2015/lin/arm-xilinx-linux-gnueabi/libc/lib/* lib -r

sudo cp ~/SDK2015/lin/arm-xilinx-linux-gnueabi/libc/sbin/* sbin -r

sudo cp ~/SDK2015/lin/arm-xilinx-linux-gnueabi/libc/usr/bin/* usr/bin/ -r

bin lib sbin

sudo cp ~/ SDK2015 /lin/arm-xilinx-linux-gnueabi/libc/usr/lib/* usr/lib/ -r

進入到usr/lib路徑下，刪除

sudo rm -rf locale

sudo rm -rf audit

sudo rm -rf bin

sudo rm -rf gconv

sudo rm *.a

sudo rm *.o

在檔案根目錄下執行

mkdir dev etc etc/dropbear etc/init.d mnt opt proc root sys tmp var var/log var/www

其中檔案都用Xilinx提供的ramdisk裡面的檔案，並拷貝到相關資料夾中

建立"etc/fstab"檔案，內容如下

touch etc/fstab

touch etc/fstab

echo "LABEL=/ / tmpfs defaults 0 0 " >> etc/fstab

echo "none /dev/pts devpts gid=5,mode=620 0 0 " >> etc/fstab

echo "none /proc proc defaults 0 0 " >> etc/fstab

echo "none /sys sysfs defaults 0 0 " >> etc/fstab

echo "none /tmp tmpfs defaults 0 0 " >> etc/fstab

建立"etc/inittab"檔案，內容如下

touch etc/inittab

echo "::sysinit:/etc/init.d/rcS " >> etc/inittab

echo "# /bin/ash " >> etc/inittab

echo "# " >> etc/inittab

echo "# Start an askfirst shell on the serial ports" >> etc/inittab

echo "ttyPS0::respawn:-/bin/ash " >> etc/inittab

echo "# What to do when restarting the init process" >> etc/inittab

echo "::restart:/sbin/init " >> etc/inittab

echo "# What to do before rebooting " >> etc/inittab

echo "::shutdown:/bin/umount -a -r " >> etc/inittab

建立"etc/passwd"檔案，內容如下

1 2	`touch etc/passwd` `echo` `"root:$1$qC.CEbjC$SVJyqm.IG.gkElhaeM.FD0:0:0:root:/root:/bin/sh"` `>> etc/passwd`

建立檔案"etc/init.d/rcS" ，內容如下

#!/bin/sh

echo "Starting rcS..."

echo "++ Mounting filesystem"

mount -t proc none /proc

mount -t sysfs none /sys

mount -t tmpfs none /tmp

echo "++ Setting up mdev"

echo /sbin/mdev > /proc/sys/kernel/hotplug

mdev -s

mkdir -p /dev/pts

mkdir -p /dev/i2c

mount -t devpts devpts /dev/pts

echo "++ Starting telnet daemon"

telnetd -l /bin/sh

echo "++ Starting http daemon"

httpd -h /var/www

echo "++ Starting ftp daemon"

tcpsvd 0:21 ftpd ftpd -w /&

echo "++ Starting dropbear (ssh) daemon"

dropbear

echo "rcS Complete"

修改許可權

sudo chmod 755 etc/init.d/rcS

sudo chown root:root etc/init.d/rcS

製作檔案系統

dd if=/dev/zero of=ramdisknew.image bs=1024 count=32768
mke2fs -F ramdisknew.image -L "ramdisk" -b 1024 -m 0
tune2fs ramdisknew.image -i 0
chmod a+rwx ramdisknew.image
sudo mount -o loop ramdisknew.image tmp_mnt_new/
sudo cp -R /home/fpgadeveloper/Zybo_Demo/XilinxFS/RootFS/* tmp_mnt_new/
cd tmp_mnt_new
cd bin/
sudo cp -rf /home/fpgadeveloper/Zybo_Demo/UART_Tools/lrzsz-0.12.20/src/lrz .
sudo cp -rf /home/fpgadeveloper/Zybo_Demo/UART_Tools/lrzsz-0.12.20/src/lsz .
cd ..
cd ..
sudo umount tmp_mnt_new
gzip ramdisknew.image
mkimage -A arm -T ramdisk -C gzip -d ramdisknew.image.gz uramdisk.image.gz

拷貝uboot dtb *uramdisk.image.gz uImage等檔案，在SDK環境下合併

可通過qspi flash 或者SD卡啟動進行系統載入
