VFS Error when boot FreeRTOS

Dear All.

 

A cusotmer re-built the FreeRTOS image following the instructions of the doc XILS008-Final-manual.pdf - "XILS008 ZYNQ AMP Linux – FreeRTOS – user guide". After created the image.ub, copied the BOOT.bin and image.ub to the SD card, Power-on ZC702 board, and report the following error message when boot:

 

********************************************************************************

... ...

NET: Registered protocol family 10

IPv6 over IPv4 tunneling driver

NET: Registered protocol family 17

VFP support v0.3: implementor 41 architecture 3 part 30 variant 9 rev 4

Registering SWP/SWPB emulation handler

Warning: unable to open an initial console.

VFS: Cannot open root device "(null)" or unknown-block(0,0)

Please append a correct "root=" boot option; here are the available partitions:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

CPU0: stopping

We think the problem may be caused by the .config after "make menuconfig", we

tried to modified the .config, but not succeed, does anyone have experience on

FreeRTOS image building, and give us some suggestions?

 

Thanks.
