  Hello, Luckfox 团队:
  
  我在uboot中修改了环境变量bootdelay，之后saveenv，但是重启（reset 或 reboot）后修改的bootdelay未生效
  以下是大致的操作过程：
  

  Code: Select all

  => printenv bootdelay 
  bootdelay=0
  => setenv bootdelay 5
  => saveenv 
  Saving Environment to envf...
  => printenv bootdelay 
  bootdelay=5
  ...
  Hit key to stop autoboot('CTRL+C'):  0 
  

  - 板子型号：Luckfox Pico Ultra W
  - 镜像类型：Luckfox_Pico_Ultra_W_EMMC_0429
  
  辛苦帮忙分析一下原因，完整的日志见附件
