今天繼續進行 eMMC 相關作業
後續還有
- image generation for firmware upgrade
- firmware upgrade process
- others uboot env
- sys led
- bootdelay
- default hw_mcsv
先來做 others uboot env
參考原本 NAND Flash 的 uboot_env.sh
點亮 system LED

set bootdelay 0 - 不讓使用者有機會去修改 uboot env
fw_setenv bootdelay 0
總共有三件事
- 點亮 system LED
- reset ethernet 1, ethernet 2 and mobile
- set bootdelay 0 - 不讓使用者有機會去修改 uboot env
直接 patch 到 uboot 吧
目前的 eMMC 的 uboot 相關的 default env 設定如下

今天的 M300 週會 borchen 也一起加入
- 下禮拜開始做 vlan web ui
- 還有 ariel 的 data usage - 要畫圖
- emmc 暫緩
- ospf 也暫緩

重上 patch 吧
- bitbake u-boot-imx -c devshell
- quilt new uboot_env_emmc_v1.0.patch
- quilt add include/configs/mx6ul_14x14_evk.h
修改 include/configs/mx6ul_14x14_evk.h
收尾 - quilt refresh
得到 patches/uboot_env_emmc_v1.0.patch
