板子使用的是imx6-saberSD
按照mfgtool下的文档Manufacturing Tool V2 Linux or Android Firmware Development Guide V2
来编译mfgtool使用的kernel
一开始是直接使用的imx6_updater_defconfig来生成uimage的,但是编译的时候出现了错误:
undefined reference to `switch_dev_register'
我很奇怪,为什么这里会出现这样的错误??官方给的配置文件一般都能正常编译通过的才对啊
随即我使能了switch class driver模块,uimage就成功编译了,然后将其放在mfgtool目录OS Firmware下
然后使用mfgtool重新下载os,但是此时出现了错误
mfgtool卡在了access boot partition 1
