+Please note that the uImage partition should have this name and it should be 4M in size. This is important in order to make the booting possible! If the u-boot comes up with weird errors, check the partitioning! I hit the scenario when the uBoot would forget the kernel I burned before or tell me that it didn't have the correct CRC number.
 Now it's necessary to provide the kernel in the tftp directory and load it via tftp:

-Now make the option to boot from USB a permanent setting:
+Please note that the memory sections in my example differ from that of other instructions you find around the web. I got a memory error and some weird system behaviour with these examples. So I decided to use some other memory segment at around 0x2000000. There's enough memory around, the NAND has 256MB. Since I don't intend to squeeze the rootfs into RAM first of all, there's plenty of space.
