购买的官方TMDSSK3358开发板，运行
processor_sdk_rtos_am335x_5_01_00_11里面的例程rtos_template_app时，在访问flah（0x08000000~0x08ffffff）或者gpmc寄存器时，程序报错退出，是因为mmu的原因吗？该如何解决？
错误信息如下：
can't find a source file at "/db/ztree/library/trees/newlib-a00/src/linaro/gcc-arm-none-eabi-7-2017-q4-major/src/newlib/libgloss/arm/swi.h
locate the file or edit the source lookup path to include its location
