In which NAND is the Boot media.</P><P>I wanted to keep my kernel and dtb in my UBIFS instead of flashing them to a separate raw partition. Since we wanted to do OTA for the device. When booting the Uboot, i am getting a error. Please help us debug the error. We are flashing the .ubimg file after flashing the uboot.</P><P></P><P>ubi0: detaching mtd1<BR />ubi0: mtd1 is detached<BR />ubi0: attaching mtd1<BR />ubi0: scanning is finished<BR />ubi0: attached mtd1 (name "mtd=1", size 496 MiB)<BR />ubi0: PEB size: 262144 bytes (256 KiB), LEB size: 253952 bytes<BR />ubi0: min./max.
