    我在MSP430F149中移植了一个UCOS系统，我有把程序重新复制到一个没有操作系统的工程里然后就没有报错？我想可能是RAM不够用啦。怎么把变量定义到FLSAH中去？

    应该是由于未连接运行库造成的LINK错误。请您尝试将option->gerenal option->library->library 选择了NORMAL DLIB。

    感谢您的回复，您的回复解决了这个问题，但还有个问题。

    Error[e16]: Segment DATA16_Z (size: 0xb20 align: 0x1) is too long for segment definition. At least 0x328 more bytes

    needed. The problem occurred while processing the segment placement command

    "-Z(DATA)DATA16_I,DATA16_Z,DATA16_N,TLS16_I,DATA16_HEAP+_DATA16_HEAP_SIZE=0200-09FF", where at the

    moment of placement the available memory ranges were "CODE:208-9ff"

    Reserved ranges relevant to this placement:

    200-9ff DATA16_I
