r58_evb_sc5806v4加载TP成功修改config 20160815 2026.7z

索智的SC5806开发板的BSP编译手册v1.2.txt 开始时间2016/8/12 18:46 结束时间2016/8/16 10:47 1、下载索智的SC5806的BSP。通过ftp下载。 地址：ftp://sochip.com.cn 账号：SC5806 密码：SC5806201601081633 Xftp 5使用自动传输BSP有点问题。ftp的传输模式有ASCII和 二进制模式。 BSP需要设置为 二进制模式。LeapFTP3.0.1.46_yfy 自动设置为二进制模式了。 估计 Xftp 5 因为设置为ASCII模式最后老是下载不完整。 2、BSP的android包的分块合并 及 解压缩： cat SC5806.android.aa SC5806.android.ab > r58_android_sc5806_20160811.tar.gz

/mnt/king_folder/studio/sdkbuild/R58/lichee/linux-3.4/modules/eurasia_km/services4/srvkm/env/linux/event.c 很显然，这是索智的一个叫king的工程师连接到了他自己的目录了。 我们自己在编译系统的时候，在本机不可能有他的目录，100%就出错了。 给出一种解决方法： rm ~/wyb/r58_evb_sc5806/lichee/linux-3.4/modules/eurasia_km/eurasiacon/binary2_sunxi_android_release/target/kbuild/services4 -rf ln -s

设想1（扩展，经过验证出错！！！！）：直接删除软连接的services4，然后拷贝过来链接源的services4，理论上应该也是可以的！ 这样就不用每次都删除链接，然后再新建链接了！！！！ rm
