Z-Stack CC2530 2.5.1a 串口问题

Other Parts Discussed in Thread: Z-STACK, CC2530

我使用CC2530配合Z-stack 2.5.1a版本的协议栈，我希望调用协议栈的串口函数收发数据，默认设置下，当终端发送128字节时，协调器接收没有问题，当我发送256字节时，就协调器就收不到终端发送的数据。后来我尝试修改默认串口接收发送缓冲区MT_UART_DEFAULT_MAX_RX_BUFF及MT_UART_DEFAULT_MAX_TX_BUFF大小为300时，协调器会收到数据，但收到的确实512个字节，而且前256数据及后256数据都不是完整的终端发送数据。我想请教该如何修改才能实现256个甚至更多字节数据发送？

    当我把MT_UART_DEFAULT_MAX_RX_BUFF改成512时，在协调器中编译出现如下错误

    Error[e104]: Failed to fit all segments into specified ranges. Problem discovered in segment XDATA_N. Unable to place 2 block(s) (0xc02 byte(s) total) in 0xa2d byte(s) of memory. The problem occurred while processing the segment placement command "-P(XDATA)XDATA_N=_XDATA_START-_XDATA_END", where at the moment of placement the available memory ranges were "XDATA:14d3-1eff"

    当大于128时可以在while里面用HalUARTWrite一个字节一个字节的发
