  你好：
  执行mmc write addr 0x2a00 0x1000之后，再执行saveenv，最后再执行reset试试；

  因为我们这边boot有a b的要同时更新，另外就是0x2a00 0x6C7算的对吗
  你可以通过下面的命令，直接刷的，
  fastboot -s udp:10.10.16.11:5554 flash boot_a boot.img
  fastboot -s udp:10.10.16.11:5554 flash boot_b boot.img

  我只更新了a，b未更新，然后从b启动了。
  这个ab更新和启动逻辑有相关文档说明吗

  您好，
  你看看之前是不是就是从B启动的，
  这个逻辑我们的用户手册是有说明的，你可以查阅我们的用户手册的

  ab都刷了后就不断重启了，这个镜像我用hbupdate下进去是可以正常启动的

您好：
1.按照你上面的描述，uboot单独更新已经成功了吧？如果没成功可以执行如下操作：
tftpboot 0x83000000 skk/uboot.img.bin
mmc write 0x83000000 0x2a00 0x1000
mmc write 0x83000000 0x3a00 0x1000
2.现阶段还碰到什么问题吗？
谢谢

  谢谢，写的长度改成0x1000就可以了，但是用计算出来的就不行:Bytes transferred/512，神奇。
  下图就是不行的

  size = （887552 + 512*0.5）/512 = 0x6c6，你计数的时候直接取整了；
