 ## Execution Instruction

 This BSP enables EMMC driver and DFS file system by default. If you need to use a file system, you can format and mount it by yourself.

+This BSP is enabled and configured with net interface driver and LwIP protocol stack by default, and note the following configuration:
+
+1. Note that `RT_LWIP_PBUF_NUM` is set to at least 256
+
+2. Note that `RT_ LWIP_ MEM_ Alignment` is set to 32. If the version other than lwip 2.0.2 in RTT is used, the `MEM_ALIGNMENT` in `lwipopts.h` needs to be modified manually because the macro is not used in other versions.
+
 ## BSP Migration

 If you need to ported the BSP to another development board of Xilinx Zynq UltraScale+ MPSOC development platform, it is also convenient. The main modifications are as follows:

-1. Memory: `psu_r5_ddr_0_MEM_0` in `zynqmp-r5.ld` (if DDR memory is less than 2G)
+1. Memory: `psu_r5_ddr_0_MEM_0` in `zynqmp-r5.ld`  and `HEAP_END` in `board.h ` (if DDR memory is less than 2G) 
 2. Main Frequency: `XPAR_CPU_CORTEXR5_0_CPU_CLK_FREQ_HZ` in `zynqmp-r5.h`
 3. Pin and Frequency of Serial Port: `rxmio`, `txmio` and `XPAR_PSU_UART_0_UART_CLK_FREQ_HZ` in `drv_uart.c`
 4. Timer Frequency: `XPAR_PSU_TTC_0_TTC_CLK_FREQ_HZ` in `drv_timer.c`
 5. SD Controller: Block device driver initialization in `drv_sdcard.c`
+6. Net interface: If the PHY chip used is not in the range of driver support, it may be necessary to realize the rate identification function of the corresponding chip in `xemacpsif_physpeed.c`. You can refer to the corresponding tutorial of Alinx.

 The parameter macro definition in `xparameters.h` does not need to be modified manually. You can directly copy the `xparameters.h` file of the development board generated in Xilinx Vitis.

 ## 使用说明

 此 BSP 默认开启了 EMMC 驱动和 DFS 文件系统，如果需要使用文件系统可以自行格式化并挂载。

+此 BSP 默认开启并配置了网卡驱动及lwip协议栈，相关配置需要注意如下几点：
+
+1. 注意将`RT_LWIP_PBUF_NUM`至少设置为256
+2. 注意将`RT_LWIP_MEM_ALIGNMENT`设置为32。若使用RTT中lwip 2.0.2以外的版本时，由于其他版本未使用该宏，需要手动修改`lwipopts.h`中的`MEM_ALIGNMENT`宏。
+

 ## 板级移植

 如果需要将BSP移植到其他 XILINX Zynq UltraScale+ MPSoCs 开发平台的开发板上也比较方便，主要修改的地方有以下几点：

-1. 内存： 如果 DDR memory 小于 2G，需要修改`zynqmp-r5.ld`链接文件中的`psu_r5_ddr_0_MEM_0` 
+1. 内存： 如果 DDR memory 小于 2G，需要修改`zynqmp-r5.ld`链接文件中的`psu_r5_ddr_0_MEM_0` 以及`board.h`中的`HEAP_END`
 2. 主频： `xparameters.h`中的`XPAR_CPU_CORTEXR5_0_CPU_CLK_FREQ_HZ`
 3. 串口引脚和频率：`drv_uart.c`中的`rxmio`, `txmio` 和`xparameters.h`中的`XPAR_PSU_UART_0_UART_CLK_FREQ_HZ`
 4. 定时器频率：`xparameters.h`中的`XPAR_PSU_TTC_0_TTC_CLK_FREQ_HZ` 
 5. SD控制器：`drv_sdcard.c`中的块设备驱动初始化
+6. 网卡驱动：若使用的PHY芯片不在驱动支持范围内，可能需要在`xemacpsif_physpeed.c`中实现相应芯片的速率识别函数，可参考ALINX的相应教程。

 以上需要修改的`xparameters.h`中的参数宏定义不需要手动修改，可以直接将Xilinx Vitis中产生的开发板的`xparameters.h`文件复制过来即可。
