fsl-image-minimal start can't mount rootfs

Question asked by biqier ben on May 18, 2018
Latest reply on May 27, 2018 by Yiping Wang

I had built the fsl-image-minimal -m ls1021atwr in sdk2.0-yocto, and deploy to the TWR-LS1021A-PC

 

after boot Uboot and kernal, the rootfs can't mount to ram, what happend?

what can i do ?

please help me!
