请问楼主是用什么flash，我用了D1的tina SDK，编译SPI nor/nand flash固件不能正常跑起来

@whycan 多谢

@whycan 按大神的做法我能编译出固件，但是rootfs挂载不起来

劳烦大神帮忙看看，我有修改过root=ubi0_5,也一样挂载不了

@yuzukitsuru 原因找到了，不小心把电源域配置关掉了，打开就能正常启动了，CONFIG_REGULATOR和CONFIG_REGULATOR_FIXED_VOLTAGE

劳烦大神帮忙看看，我有修改过root=ubi0_5,也一样挂载不了

@whycan 按大神的做法我能编译出固件，但是rootfs挂载不起来

@whycan 多谢

请问楼主是用什么flash，我用了D1的tina SDK，编译SPI nor/nand flash固件不能正常跑起来

貌似都不能识别RTSP地址

缺少t113_linux_cedarx.conf文件，拷贝一个类似的就好了
