rev 0.1   快乐虾 http://blog.csdn.net/lights_joy/ lights@hb165.com   本文适用于 ADI bf561 DSP 优视BF561EVB开发板 uclinux-2008r1.5-rc3(smp patch) Visual DSP++ 5.0(update 5)   欢迎转载,但请保留作者信息   有一个错误: [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[early_printk.doj](bsz)         arch-kernel.dlb[setup.doj](bsz)         arch-mm.dlb[init.doj](bsz) ……….. 造成这个错误的原因在于,有一些段中的数据是需要初始化为0的,gcc是以.bss做为默认的段名,而vdsp则是以bsz做为默认的名称。在uclinux的链接文件中可以发现这样的定义:      .bss :      {          . = ALIGN(4);          ___bss_start = .;          *(.bss .bss.*)          *(COMMON)          . = ALIGN(4);          ___bss_stop = .;          __end = .;      } 相应的在uclinux.ldf中修改为:       uclinux_bss ZERO_INIT       {          INPUT_SECTION_ALIGN(4)                ___init_end = .;                ___bss_start = .;                INPUT_SECTIONS($LIBRARIES_CORE_A(.bss .bss.*))                INPUT_SECTIONS($LIBRARIES_CORE_A(bsz))                INPUT_SECTIONS($LIBRARIES_CORE_A(COMMON))                          INPUT_SECTION_ALIGN(4)          . = (. + 3) / 4 * 4;                ___bss_stop = .;                __end = .;       } > MEM_UCLINUX_BSS
