malloc Out of memory after ubiattach operation

[Madhu koriginja]

After barebox up, I erased the /dev/nand0.rootfs.bb using erase command.
kernel is already present in the /dev/nand0.kernel.
After ubiattach command, if I try the boot I am getting the below error.
Actually my aim is to boot the kernel and it should mount to ubifs, to
simplify the problem and reproduce the same I am just trying the boot after
ubiattach instead of preparing the ubi0 device.
Barebox >/ubiattach /dev/nand0.rootfs

Barebox >/ boot
booting kernel of type uimage from /dev/nand0.kernel.bb
bootm /dev/nand0.kernel.bb

ERROR: out of memory

Please somebody suggest me some pointer to solve this issue.

Thanks,
