arm-none-eabi/bin/ld: build/com.zubax.gnss.elf section `.text' will not fit in region `flash'

出现如下错误：

/arm-none-eabi/bin/ld: build/com.zubax.gnss.elf section `.text' will not fit in region `flash'
/arm-none-eabi/bin/ld: region `flash' overflowed by 5869 bytes

bootloader编译，.text已经超过预设大小。修改方案有两个：

精简代码
修改MEMORY预设值

ChibiOS
以ChibiOS为例，修改ld.ld文件和Makefile文件

# vi ld.ld

MEMORY
{
MEMORY
{
    flash : org = 0x08000000, len = 32512/*增大此值*/   /* 32K for the bootloader minus 256 for the signature */
    ram   : org = 0x20000100, len = 65280   /* First 256 bytes are reserved for bootloader/app communication */
}
}

# vi Makefile

APPLICATION_OFFSET = 32512  //与ld.ld中修改值对应，代码中会用到
