Uboot 命令TFTP 下载RT-Smart系统镜像并烧写到emmc



上回说到Windows下通过 Uboot  TFTP 方式下载和启动rt-smart 内核，　其实只是通过TFTP下载rt-smart 内核到内存，启动开发板，并不是下载到emmc(ROM),怎么烧写emmc呢？　下面讲解


准备

•     设置TFTP服务
•     设置开板板IP
•     设置服务器TFTP
  

请到上回Windows下通过 Uboot  TFTP 方式下载和启动rt-smart 内核

下载系统镜像

1. => tftp emmc.img
   
2. Using ethernet@02188000 device
   
3. TFTP from server 192.168.0.26; our IP address is 192.168.0.100
   
4. Filename 'emmc.img'.
   
5. Load address: 0x80800000
   
6. Loading: #################################################################
   
7.          #################################################################
   
8.          .......
   
9.          ####################
   
10.          1.6 MiB/s
    
11. done
    
12. Bytes transferred = 69207040 (4200400 hex)

复制代码

提示下载启始地址0x80800000，大小69207040Bytes　／512Bytes/blk = 135170 转换为16进制　0x21002

写入emmmc

按上面计算写emmc命令为mmc write 0x80800000 0 21002

1. => mmc write 0x80800000 0 21002
   
2. 
   
3. MMC write: dev # 1, block # 0, count 135170 ... 135170 blocks written: OK

复制代码

注：从内存地址0x80800000开始　写到emmc０blk开始写　135170(x21002) blks(块）　

　这时看uboot环境还是之前的，这内存的，boo可以直接启动

设置uboot环境变量并保存：
第二次不了，环境变量，是新系统镜像的，所以要重新设置一下

1. setenv bootcmd "fatload mmc 1:1 0x80001000 /kernel/rtthread.bin; dcache flush; go 0x80001000"
   
2. saveenv

复制代码

RT-Smart系统命令：

1. boot

复制代码

执行结果:

1. => setenv bootcmd "fatload mmc 1:1 0x80001000 /kernel/rtthread.bin; dcache flush; go 0x80001000"
   
2. => saveenv
   
3. Saving Environment to MMC...
   
4. Writing to MMC(1)... done
   
5. => boot
   
6. reading /kernel/rtthread.bin
   
7. 1182208 bytes read in 52 ms (21.7 MiB/s)
   
8. ## Starting application at 0x80001000 ...
