有一个错误：
[Error li1040] "./uclinux.ldf":581 Out of memory in output section 'L1_code' in processor 'p0'
Total of 0xc2 word(s) were not mapped.
For more details, see 'linker_log.xml' in the output directory.
看看L1_code里面放了什么东西：
L1_code
{
INPUT_SECTION_ALIGN(4)
__stext_l1 = .;
__CORE = 0;
INPUT_SECTIONS($OBJECTS_CORE_A(L1_code) $LIBRARIES_CORE_A(L1_code))

/*$VDSG<insert-input-sections-at-the-start-of-l1_code> */
/* Text inserted between these $VDSG comments will be preserved */
/*$VDSG<insert-input-sections-at-the-start-of-l1_code> */

INPUT_SECTIONS($OBJECTS_CORE_A(VDK_ISR_code) $LIBRARIES_CORE_A(VDK_ISR_code))
INPUT_SECTIONS($OBJECTS_CORE_A(cplb) $LIBRARIES_CORE_A(cplb))
INPUT_SECTIONS($OBJECTS_CORE_A(cplb_code) $LIBRARIES_CORE_A(cplb_code))
INPUT_SECTIONS($OBJECTS_CORE_A(noncache_code) $LIBRARIES_CORE_A(noncache_code))
INPUT_SECTIONS($OBJS_LIBS_INTERNAL_CORE_A(program))
INPUT_SECTIONS($OBJS_LIBS_NOT_EXTERNAL_CORE_A(program))
INPUT_SECTIONS($OBJECTS_CORE_A(program) $LIBRARIES_CORE_A(program))

/*$VDSG<insert-input-sections-at-the-end-of-l1_code> */
/* Text inserted between these $VDSG comments will be preserved */
/*$VDSG<insert-input-sections-at-the-end-of-l1_code> */
INPUT_SECTIONS($LIBRARIES_CORE_A(.l1.text))

INPUT_SECTION_ALIGN(4)
__etext_l1 = (. + 3) / 4 * 4;

} > MEM_A_L1_CODE
把L1_code和program段的内容移到uclinux_text中：
uclinux_text
{
__text = .;
_text = .;
__stext = .;

INPUT_SECTIONS($OBJECTS_CORE_A(L1_code) $LIBRARIES_CORE_A(L1_code))
INPUT_SECTIONS($OBJS_LIBS_INTERNAL_CORE_A(program))
INPUT_SECTIONS($OBJS_LIBS_NOT_EXTERNAL_CORE_A(program))
INPUT_SECTIONS($OBJECTS_CORE_A(program) $LIBRARIES_CORE_A(program))
/*
TEXT_TEXT
SCHED_TEXT
LOCK_TEXT
KPROBES_TEXT
*(.text.*)
*(.fixup)

. = ALIGN(16);
___start___ex_table = .;
*(__ex_table)
___stop___ex_table = .;
*/
INPUT_SECTION_ALIGN(4)
__etext = .;
} > MEM_UCLINUX_TEXT
