ubi attach error in kernel

[shreyansbadjaty]

Hello All,

I am working on a custom board, which is based on the 14x14 evk,

I am facing issue with root file system in kernel.

I have updated the QSPI NOR flash with U-Boot, Kernel (4.1.15_2.0.0) device tree and root.ubi as file system.

I am able to bring the U-boot up and can mount the root.ubi, Following is the output for command-

Hello Igor,

Thanks for your response.

My board is already up with u boot and kernel is starting.

However mounting of file system does not work. 

I have accidentally discovered that when I start the U boot from MFG tool and then start the kernel, same setup works.

Though when i flash the same U boot to QSPI and start the board from QSPI then file system does not get attach.

I found this little confusing. Any insight will be helpful.
