开发工具：ads1.2 或 gcc for linux 说明：可以供阅读嵌入式fs时参考。内含flash file system驱动原理介绍，以及uclinux和usos2下的各种文件系统实现(yaffs2,ffs,cf card,sd card,fat等),主要是周立功和优龙的代码。-Tools : ads1.2 or gcc for linux : can be read for Embedded fs reference. Intron flash file system driver

使用互斥信号量解决ucosii中的优先级反转,The use of mutex semaphores to solve the ucosii Priority Inversion

在本实验中，体现嵌入式实时内核的优先级抢占调度的策略，并显现由于共享资源的互斥访问而出现的优先级反转现象-In this experiment, reflecting the priority of embedded real-time kernel preemptive scheduling strategy, and appear as mutually exclusive access to shared resources and priority inversion phenomeno

it detects the priority inversion where the high priority task need not have to wait for low priority task
