使用Z-Stack 3.0.1栈，想开启UART功能，但是在编译标志中添加了
HAL_UART=TRUE
HAL_UART_ISR=1
HAL_UART_DMA=2
后，发现编译出错：
Error[e16]: Segment XDATA_Z (size: 0x1e07 align: 0) is too long for segment definition. At least 0x208 more bytes needed. The problem occurred while processing the segment placement command "-Z(XDATA)XDATA_Z,XDATA_I=_XDATA_START-_XDATA_END", where at the moment of placement the available memory ranges were "XDATA:301-1eff"
同样的方式在 Z-Stack 2.5.1a上没出错
