STM32链接脚本执行出现语法错误的排查求助

我正在学习Gbati Israel所著《裸机嵌入式C编程》，尝试实现STM32_NUCLEO-F411开发板的LED慢闪烁功能，严格遵循书中的三步编译流程操作：

• 步骤1：编译main.c生成目标文件

  arm-none-eabi-gcc -c -mcpu=cortex-m4 -mthumb -std=gnu11 main.c -o main.o
  

• 步骤2：编译启动文件生成目标文件

  arm-none-eabi-gcc -c -mcpu=cortex-m4 -mthumb -std=gnu11 stm32f411_startup.c -o stm32f411_startup.o
  

• 步骤3：链接所有目标文件生成可执行文件

  rm-none-eabi-gcc -nostdlib -T stm32_ls.ld *.o -o 3_LinkerAndStartup.elf.elf
  

执行链接命令后持续出现以下错误：

c:/program files (x86)/gnu arm embedded toolchain/10 2021.10/bin/../lib/gcc/arm-none-eabi/10.3.1/../../../../arm-none-eabi/bin/ld.exe:stm32_ls.ld:18: syntax error
collect2.exe: error: ld returned 1 exit status

根据错误提示检查了stm32_ls.ld脚本的第18行，但未发现明显问题，完整的链接脚本内容如下：

/*1.Entry Point*/
ENTRY(Reset_Handler)


/*2.Memory definitions*/

MEMORY
{
    FLASH(rx):ORIGIN =0x08000000,LENGTH =512K
    SRAM(rwx):ORIGIN =0x20000000,LENGTH =128K
}

_estack = ORIGIN(SRAM)+LENGTH(SRAM);
 
 /*3.Indicate required heap and stack size*/
__max_heap_size = 0x200;
__max_stack_size = 0x400;

/*Sections*/
SECTIONS
{
     /*first section of output file*/
    .text :
    {
      . = ALIGN(4);
      *(.isr_vector_tbl)  /*merge all .isr_vector_tbl sections of input files*/
      *(.text)             /*merge all .text sections of input files*/
      *(.rodata)           /*merge all .rodata sections of input files*/
      . = ALIGN(4);
     _etext = .;          /*Create a global symbol to hold end of text section*/
    }>FLASH
        

    /*second section of output file*/

    .data :
    {
     . = ALIGN(4);
    _sdata = .;   /*Create a global symbol to hold start of data section*/
      *(.data)
     . = ALIGN(4);
    _edata = .;   /*Create a global symbol to hold end of data section*/
    } > SRAM AT> FLASH  /*>(vma) AT> (lma)*/
    
    
    /*third section of output file*/
    .bss :
    {
     . = ALIGN(4);
    _sbss = .;  /*Create a global symbol to hold start of bss section*/
    *(.bss)  /*merge all .bss sections of input files*/
     . = ALIGN(4);
    _ebss = .;  /*Create a global symbol to hold end of bss section*/
    }> SRAM
}
