The BSP is configured by default to have its filesystem run out of RAM memory, hence being volatile. If you want to persist data acrosse reboots, you can store this data under a storage device (SD Card, NAND Flash, USB pen driver, etc...), or configure your image to be "ROM only" where you would have to choose a non-volatile location to store your image's filesystem.
Hi,
I'm facing similar problem on EVM8148 trying to get root filesystem on SD card
I'm unable to bootup, it hangs during initial kernel phase, can you pls tell me how you solved the problem?

..hangs here
I've used the patch given by TI for SD card persistent storage..
Attached platform.reg and sdhc.reg. Can you tell me if I've missed out on something...
