请教各位专家：
开发环境：ccs5.5
msdk ：mcsdk_2_01_02_06
目前在调试6672的emif norflah启动，我做了一个点灯的测试程序
1、裸机情况下可以正常启动。
2、加入sysbiso后，我在mian函数也点了几次灯，发现可以正常工作，然后在创建的任务里进行灯闪烁，程序无法正常运行，
3、我在编译时出现如下警告，不知与创建任务失败是否有关系
warning #10278-D: LOAD placement specified for section ".text:decompress:ZI:__TI_zero_init:rts6600_elf.lib<copy_zero_init.obj>". This section contains decompression routines required for linker generated copy tables and C/C++ auto-initialization. Must ensure that this section is copied to run address before the C/C++ boot code is executed or is placed with single allocation specifier (ex. "> MEMORY").
目前我的分析是，创建任务失败，导致程序在不停的重启
下面是我的boot.asm,主要是执行程序搬移
