This will be the UBL which runs before U-Boot gets a chance to run. Just before Stefano Babic's work on the dm365 platform all davinci U-Boot ports configured CONFIG_SKIP_LOWLEVEL_INIT and thus relied on being loaded by some other entity into RAM to the link address specified during compilation. In such setups U-Boot is actually a payload in an AIS image. There is some documentation out there on the web ([1], esp. [2]) - if you have further questions, go ahead ;) Cheers Detlev [1] http://processors.wiki.ti.com/index.php/Category:OMAPL1 [2] http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L138 -- Deutsches Grundgesetz Artikel 21 Absatz 1: Die Parteien wirken bei der politischen Willensbildung des Volkes mit.
