经过前述处理，VDSP提示错误：

[Warning li2060] The following input section(s) that contain program code

and/or data have not been placed into the executable for processor 'p0'

as there are no relevant commands specified in the LDF:

arch-kernel.dlb[init_task.doj](.data.init_task)

在vmlinux.lds.s中这样定义.data.init_task段：

.data :

{

/* make sure the init_task is aligned to the

* kernel thread size so we can locate the kernel

* stack properly and quickly.

*/

__sdata = .;

. = ALIGN(THREAD_SIZE);

*(.data.init_task)

. = ALIGN(32);

*(.data.cacheline_aligned)

#if !L1_DATA_A_LENGTH

. = ALIGN(32);

*(.data_l1.cacheline_aligned)

#endif

DATA_DATA

*(.data)

CONSTRUCTORS

. = ALIGN(THREAD_SIZE);

__edata = .;

}

由于.data段在之前已经添加，故直接在LDF文件的.data段做修改：

uclinux_data

{

/* make sure the init_task is aligned to the

* kernel thread size so we can locate the kernel

* stack properly and quickly.

*/

__sdata = .;

INPUT_SECTION_ALIGN(8192)

INPUT_SECTIONS($LIBRARIES_CORE_A(.data.init_task))

/*

. = ALIGN(32);

*(.data.cacheline_aligned)

#if !L1_DATA_A_LENGTH

. = ALIGN(32);

*(.data_l1.cacheline_aligned)

#endif

DATA_DATA

*(.data)

CONSTRUCTORS

*/

INPUT_SECTION_ALIGN(8192)

__edata = .;

} > MEM_UCLINUX_DATA
