Unable to mount root fs on unknown-block

I have created a bootable SD Card for the S32R45 EVB by writing the fsl-image-auto-s32r45evb.sdcard image file(use Win32DiskImager).

Insert the SD card into the S32R45 EVB SD slot, and power-on the EVB. It seems unnormal, points out “unable to mount root fs on unknown-block”.

How can I do to solve it?

Hello, 

 

It seems the second partition EXT3 where the rootfs resides, was not written correctly. 

Could you insert the SD card in a Linux host and make sure you get 2 partitions in the SD card?

The first one must be a FAT32 and the second one Ext3/Ext4. 

 

Saludos,

Alejandro
