注意编译选项：
ZTOOL_P1
MT_TASK
HAL_UART=TRUE
SERIAL_APP_PORT=0
BUILD_ALL_DEVICES
1、使用ISR不使用DMA hal_board_cfg.h文件中
#if HAL_UART
#ifndef HAL_UART_DMA
#if HAL_DMA
#if (defined ZAPP_P2) || (defined ZTOOL_P2)
#define HAL_UART_DMA 2
#else
#define HAL_UART_DMA 1
#endif
#else
#define HAL_UART_DMA 0
改为
#if HAL_UART
#ifndef HAL_UART_DMA
#if HAL_DMA
#if (defined ZAPP_P2) || (defined ZTOOL_P2)
#define HAL_UART_DMA 2
#else
#define HAL_UART_ISR 1
#endif
#else
#define HAL_UART_DMA 0
#endif
#endif
1、修改优先级以及uart
