iboot调试

         看到友善之臂的superboot确实很帅,也想实现这样的功能.无意间发现google code中有个开源的iboot.于是拿来用一用;结果调试的时候发现卡壳了,
该开源代码是基于SD卡的,而我打算使用在nand中.目前nand能够读取rtt-tiny6410.bin启动,但是问题在于rtt启动运行一会就死了.

这个或许是应为配置的
#define RT_INIT_THREAD_STACK_SIZE (64*1024)
难道配置过大?我的可是256MB的sdram啊
更改了栈大小设置后为4K运行一长段时间后,悲剧来了

结果今天改了很多次stack都是运行就把stack耗尽了.不知道为何.改大了想先前情况,分配stack为0,是不成功么???改小了就被耗尽了
感觉就是stack泄露了.
