设置HAL_UART=TRUE，编译出现问题

在看simpleBLEPeripheral.c，想将LCD上显示的数据在串口上显示。

Options里的Preproce下设置是：

HAL_LCD=TRUE

HAL_LED=FALSE
HAL_UART=TRUE
LCD_TO_UART

编译后出现

Warning[w52]: More than one definition for the byte at address 0x6b in common segment INTVEC. It is defined in module "hal_uart" as well as in module "hal_key"

串口没法使用，这是怎么回事？
