Is there a canonical description of how to making a > boot image and put it on SD? Perhaps I was doing that incorrectly. You can use the article from the Compulab wiki: http://compulab.co.il/workspace/mediawiki/index.php5/CM-FX6:_U-Boot:_Creating_a_bootable_SD_card This article assumes that both SPL and U-Boot reside on a single binary at the right offsets. The following article describes the steps for creating this joined image: http://compulab.co.il/workspace/mediawiki/index.php5/CM-FX6:_U-Boot:_Building_Images#Building_the_firmware_images > > Thanks, > Simon >
