arm-none-eabi-ld -Tuser/hc32l13x.lds -o grbl_hc32l13x.elf user/interrupts_hc32l13x.o user/system_hc32l13x.o user/main.o user/startup_hc32l13x.o -lm -Map=grbl_hc32l13x.map
arm-none-eabi-ld: cannot find -lm
makefile:33: recipe for target 'link' failed

改为在gcc时传入-T参数

$(CC)gcc $^ -Tuser/hc32l13x.lds $(LDFLAG) -Map=$(target).map -o $(target).elf

出错：arm-none-eabi-gcc: error: unrecognized command line option '-Map=grbl_hc32l13x.map'

再次改为：

$(CC)gcc $^ -Tuser/hc32l13x.lds $(LDFLAG) -Wl,-Map=$(target).map -o $(target).elf

编译通过。

附上.lds:

SECTIONS{. = 0;.text : {user/startup_hc32l13x.o*(.text)}.data : {*(.data)}.bss : {*(.bss)}
}SECTIONS{. = 0;.text : {       /*写成 .text:{ 不对，要有空格。*/*(.text)    /*写成 *{.text} 不对，要为小括号。*/}.data : {*(.data)}.bss : {_sbss = .;         /* define a global symbol at bss start */__bss_start__ = _sbss;*(.bss)*(.bss*)*(COMMON). = ALIGN(4);_ebss = .;         /* define a global symbol at bss end */__bss_end__ = _ebss;}
}
