软硬件环境：
peter@u14:~/share/r329-evb5$ lunch r329_evb5-tina
============================================
TINA_BUILD_TOP=/home/peter/share/r329-evb5
TINA_TARGET_ARCH=aarch64
TARGET_PRODUCT=r329_evb5
TARGET_PLATFORM=r329
TARGET_BOARD=r329-evb5
TARGET_PLAN=evb5
TARGET_BUILD_VARIANT=tina
TARGET_BUILD_TYPE=release
TARGET_KERNEL_VERSION=4.9
TARGET_UBOOT=u-boot-2018
TARGET_CHIP=sun50iw11p1
============================================
其中，~/share/r329-evb5是SDK顶层目录

启动打印：
[65]HELLO! BOOT0 is starting!
[68]BOOT0 commit : 97444f5
[70]set pll start
[73]periph0 has been enabled

代码里搜索第一行里的“starting!”：
peter@u14:~/share/r329-evb5$  grep "starting!" --binary-files=without-match --exclude-dir=\.git --exclude-dir=\.repo --exclude=*tags -nwr ./
peter@u14:~/share/r329-evb5$  grep "starting!" --exclude-dir=\.git --exclude-dir=\.repo --exclude=*tags -nwr ./
Binary file ./device/config/chips/r329/bin/boot0_nand_sun50iw11p1.bin matches
Binary file ./device/config/chips/r329/bin/sboot_sun50iw11p1.bin matches

大佬们，是代码文件里本身没有“HELLO! BOOT0 is starting!”，还是我搜索的问题？还是其他的原因？
