Win32DiskImager下载链接Win32 Disk Imager download | SourceForge.net 正点原子的imxdownload由于包含了烧录的功能但在WLS上无法识别SD卡因此无法使用所以可以将imxdownload的烧录功能都取消让程序生成一个可烧录的镜像文件即可。

执行
./imxdownload2 led.bin
注led.bin是工程中需要的.bin文件 此时生成了.imx (可在Linux下用dd命令烧录), img (可在windows下用Win32DiskImager烧录SD卡)。load.img的内容是在load.imx基础上偏移了1K 字节这样可以直接烧录到SD卡。 3、Win32DiskImager烧录SD卡
使用Win32DiskImager打开需要烧录的.imx文件进行点击“写入”即可。 写入成功后将SD卡插回开发板上选择SD卡启动程序成功运行。 上述方法简单好用对新手友好但多了一步烧录的步骤如果觉得繁琐可以参考
