hi:
   linux主机环境下，安装好scons工具，修改rt-thread/bsp/zynq7000rtconfig.py文件后，gcc为Xilinx 官方的sdk下的arm-gcc，rt-thread v2.1.0版本,ZYNQ7000平台，进行编译报错。

首先是pthread_t系列数据类型不兼容：

```ganhuaren@myubuntu:~/samba/rt-thread$ cd ./bsp/zynq7000/
ganhuaren@myubuntu:~/samba/rt-thread/bsp/zynq7000$ scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
scons: building associated VariantDir targets: build/bsp
CC build/bsp/applications/application.o
In file included from /home/ganhuaren/samba/rt-thread/include/components.h:72:0,
                 from applications/application.c:23:
/home/ganhuaren/samba/rt-thread/components/pthreads/pthread.h:43:21: error: conflicting types for 'pthread_t'
 typedef rt_thread_t pthread_t;
                     ^
In file included from /opt/Xilinx/SDK/2016.2/gnu/arm/lin/arm-xilinx-linux-gnueabi/libc/usr/include/sys/types.h:270:0,
                 from /home/ganhuaren/samba/rt-thread/components/finsh/finsh.h:60,
                 from /home/ganhuaren/samba/rt-thread/include/components.h:33,
                 from applications/application.c:23:```

在关闭pthread接口（禁掉RT_USING_PTHREADS宏）后又报缺reent.h文件：

```ganhuaren@myubuntu:~/samba/rt-thread/bsp/zynq7000$ scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
scons: building associated VariantDir targets: build/bsp

CC build/bsp/drivers/uart.o
CC build/kernel/components/libc/newlib/syscalls.o
/home/ganhuaren/samba/rt-thread/components/libc/newlib/syscalls.c:1:19: fatal error: reent.h: No such file or directory
 #include <reent.h>
                   ^
compilation terminated.
scons: *** [build/kernel/components/libc/newlib/syscalls.o] Error 1
scons: building terminated because of errors.```

最后编译报错就是报zynq7000.ld文件中缺.rel.plt 段

最终在解决掉这些编译错误后，编译出来的镜像文件rtthread-zynq7000.elf下载到板子里跑步起来，程序会飞，初步定位到是在void rt_hw_board_init()函数。

我想问的是，为啥会出现编译缺文件，缺段这种错误......rtthread没有在zynq7000上维护更新吗？rtthread还能不能在z7用啊？

hi:
  在 [https://launchpad.net/gcc-arm-embedded](https://launchpad.net/gcc-arm-embedded)下载了最新的gcc-arm-none-eabi-5_4-2016q3-20160926-linux.tar编译器安装好后，的确没有编译错误了。镜像下载下去后，在解决了串口管脚，时钟（官方代码和自己用的zynq7000板卡配置区别）差异后，串口终端有了输出：

目前我还在定位是产生data abort原因，进度很慢（无仿真器单步调试）。哪位能帮我定位是啥问题吗？不胜感激
