dear,

附件是我上传的bootloader工程,开发环境是MDK,

直接烧录app程序能够正常运行,通过boot烧录app程序能够正常烧录,且烧录完成之后在调试中重新读取app的程序进行比对,是正确的,

问题:通过boot升级app 程序不能实现跳转,已经连续调试了几天找不出问题,在此请freescale的工程师帮忙看一下,问题出在哪里,附件是我的bootloader工程,谢谢~

1、在APP的.S文件注释掉了如下:

                ;IF      :LNOT::DEF:RAM_TARGET

                ;AREA    |.ARM.__at_0x400|, CODE, READONLY

                ;DCB     BackDoorK0, BackDoorK1, BackDoorK2, BackDoorK3

                ;DCB     BackDoorK4, BackDoorK5, BackDoorK6, BackDoorK7

                ;DCB     0xFF,       0xFF,       0xFF,       0xFF

                ;DCB     0xFF,       FPROT,      FSEC,       FOPT

                ;ENDIF
