索智官方给了 名为：eMMC_Patch_Release 的补丁包,我这边把S3的SDK包解压后，就把这个补丁文件夹覆盖了上去。
1.修改build/envsetup.sh的文件内容
"uboot")
echo "zmake uboot"
croot
cd ./bootloader/u-boot-2011.09
./build.sh -p sun8iw8p1_spinand_emmc --改了传参
croot
;;
2.之后先导入环境变量：
root@ubuntu:/home/s3/s3-emmc# source build/envsetup.sh
TARGET_TOP=/home/s3/s3-emmc
TARGET_OUT=/home/s3/s3-emmc/out/sun8iw8p1-linaro-5.3/linux/common/buildroot/
BUILD_SYS_DIR=/home/s3/s3-emmc/build

LICHEE_LINUX=/home/s3/s3-emmc/linux-3.4

LICHEE_CHIP=sun8iw8p1
TARGET_PRODUCT=zeta
BUILDROOT_OUT=/home/s3/s3-emmc/out/sun8iw8p1-linaro-5.3/linux/common/buildroot/
3.然后使用zmake all进行编译，由于初次使用全志的SDK进行打包编译，之后会生成一个sun8iw8p1_linux_zeta-cdr_uart0.img的镜像
问题一：
1.这个sd卡的镜像也是用PhoenixSuit进行烧录吗？我试了一下，进行到这里就不行了

之后我就参考V3S的烧录方式，首先制作u-boot-sun8iw8p1.bin，然后制作zimage,rootfs.tar.bz2,最后参考《制作荔枝派Zero开发板(全志V3s) TF/SD卡启动盘》https://whycan.cn/t_547.html，进行制作，发现做完的SD卡也是没法启动，到这里我有些懵逼了。
问题二：是否我还需要修改其他文件来使得SD卡能正常作为启动介质呢？
谢谢各位，感激不尽

仔细核对了一下 荔枝派 V3s 的文档， 基本操作没有太大问题。
PWM_CTRL_REG 0x00 PWM Control Register
PWM_CH1_PERIOD 0x08 PWM Channel 1 Period Register用 busybox 里面的 devmem 把这两个寄存器读出来看看:
devmem 0x01C21000
devmem 0x01C21008
# devmem 0x01C21000
0x002F8000
# devmem 0x01C21008
0x5DBF12C0
pwm控制寄存器：
0000 0000 0010 1111 1000 0000 0000 0000
PWM_CH1_PRESCAL=1 PWM_CH1_EN=1 PWM_CH1_CLK_GATING=1（Gating the Special Clock for PWM1 (0: mask, 1: pass).）
设置的参数：
0101 1101 1011 1111 0001 0010 1100 0000
PWM_CH1_ACT_CYS=4800
PWM_CH1_ENTIRE_CYS=23999
我不知道，是不是pwm控制器里面有哪些位是不是还得设置一下。

red_led {

gpios = <&pio 5 6 GPIO_ACTIVE_LOW>; /* PE6 */

};上面的命令都可以执行成功，但是PE6脚输出一直是高电平,没有PWM波形的输出，这个哪个问题导致的呀
