-'''U-Boot''' is a [[bootloader]] which can be used on the [[Neo 1973]] and [[Neo FreeRunner]]. It takes care of device functionality until the operating system is booted. This includes [[USB DFU]] for [[Flashing the Neo FreeRunner]], a splash screen, a boot menu, a console for [[U-Boot commands]], configuration via [[U-Boot environment]], and loading a [[kernel]].

 === Neo 1973 ===
-Doing bootloader development on the [[Neo 1973]] is a bit more tricky.  First, we don't have any NOR flash.  Second, there is no other way to boot _but_ from NAND.  Therefore, we also don't have a USB downloader like the QT2410.

 The main problem is:  The [[S3C2410 Steppingstone]] unconditionally copies the first 4k of flash into its internal SRAM.   That SRAM segment stays unconditionally mapped at physical address zero. How do we get around this
