• 第一步、复制自己的参考的板级文件

    cp   arch/arm/mach-omap2/board-am335xevm.c   arch/arm/mach-omap2/board-aplex_ECM_5412.c

• 第二步、在对应的kconfig ,Makefile 里面增加对应的代码

    // vim arch/arm/mach-omap2/Makefile//  这是原来的257 obj-$(CONFIG_MACH_AM335XIAEVM)      += board-am335xevm.o258 obj-$(CONFIG_MACH_APLEX_ECM_5412)   += board-aplex_ECM_5412.o// 后面增加

    // 参考原来的// vim arch/arm/mach-omap2/Kconfig347 config MACH_APLEX_ECM_5412348     bool "Aplex ECM_5412"349     depends on SOC_OMAPAM33XX350     default  n351 352 config MACH_AM335XEVM353     bool "AM335X Evaluation Module"354     depends on SOC_OMAPAM33XX355     default n

• 第三步、 修改并添加一些匹配代码

    // vim  arch/arm/mach-omap2/board-aplex_ECM_5412.c// 将原来的修改过来3707 MACHINE_START(APLEX_ECM_5412, "aplex_ECM_5412")3708     /* Maintainer: Texas Instruments */3709     .atag_offset    = 0x100,3710     .map_io     = am335x_evm_map_io,3711     .init_early = am33xx_init_early,3712     .init_irq   = ti81xx_init_irq,3713     .handle_irq     = omap3_intc_handle_irq,3714     .timer      = &omap3_am33xx_timer,3715     .init_machine   = am335x_evm_init,3716 MACHINE_END

    // 添加自己的配置// vim arch/arm/tools/mach-types1129 am335xevm       MACH_AM335XEVM      AM335XEVM       35891130 am335xiaevm     MACH_AM335XIAEVM    AM335XIAEVM     36841131 aplex_ECM_5412  MACH_APLEX_ECM_5412 APLEX_ECM_5412  3688

    vim arch/arm/plat-omap/include/plat/uncompress.h里面197         DEBUG_LL_AM33XX(1, aplex_ECM_5412); 

• 最后， 在 make menuconfig 里面添加

    // make menuconfig System Type  --->TI OMAP2/3/4 Specific Features  --->[*] Aplex ECM_5412

• 编译

    make -j4

• 对应的 uboot 还要作修改。

    仅仅只是 kernel 的修改还是不够的，虽然刚才编译通过了，但是将这个镜像烧入，发现还是无法起来，这是为什么呢。查了一下原因，发现是 uboot 中还要作相对应的修改。

    板级文件的复制board/aplex/ECM_5410

    //  在uboot 中添加相对应的宏：//  arch/arm/include/asm/mach-types.h3315 #define MACH_TYPE_TIAM335EVM           35893316 #define MACH_TYPE_TIAM335IAEVM         36843317 #define MACH_APLEX_ECM_5412            3688

    // 在板级文件中修改相对应的参数。// vim board/aplex/ECM_5412/evm.c436     if (board_id == IA_BOARD)437         gd->bd->bi_arch_number = MACH_TYPE_TIAM335IAEVM;438     else439         gd->bd->bi_arch_number = MACH_APLEX_ECM_5412;

    cp include/configs/ok335x.h  include/configs/ECM_5412.h

    最后还要在 boards.cfg 里面加入对应规则ECM_5416                     arm         armv7       ECM_5416            aplex          ti81xx

    make ECM_5412   O=out -j4
