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
