Follow SABRE_SD_User_Guide, try to boot from rootfs on SD, never work.

I put u-boot, kernel and rootfs into the same SD. Kernel boots up, but continue waiting for rootfs, which is mmcblk1p1.

Hey Ding,

What Linux package did you download?

Did you set the u-boot environment variables as specified in section 8.2 of i.MX_6_SABRE-SD_Linux_User's_Guide (for Linux 3.10.17) or section 9.2 of i.MX_6Dual6Quad_SABRE-SD_Linux_User's_Guide (for Linux 3.0.35)?

Could you provide the serial output while the board is booting up and your u-boot environment variables?

Regards,

Nick Saulnier
