I am trying to implement OpenWiFi in Zed Board. But after loading Kernel its getting stuck with following error,

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)

I using prebuilt image provided in this page and the image built from scratch following the steps provided in Kuiper_md, got same error for both. I have followed step 2 in Quick Start before starting the board. And whenever I tried to run scp command in Update Fpga the connection was not getting established, also I have set Host IP as mentioned (192.168.10.1). I am not sure what I have done wrong . Prior to image flash I have formatted SD card to FAT32. Please help me resolve the issue.

Thanks in Advance

I have solved the issue. It was problem regarding the SD flashing tool I used. Then I used different tool mentioned here. I would advice to use a 32GB SD card not more than that. Because when I used 64GB it was giving me troubles. I flashed Kuiper image and then followed this steps. After that I am able to boot with no kernel panic. Hope it helps someone in need.
