We can not run from flash because: The code has not been relocated the flash is not persistent We do load the flash/elf file into DRAM dealing with elf issues along the way and then execute it. We can do something similar for devicetrees, actually just passing Linux the offset from the begining of flash to the devicetree would be sufficient. Or if finding the devicetree inside the bitsstream can be accomplished fairly simply, just passing the offset of the bit file. -- Dave Lynch DLA Systems Software Development: Embedded Linux 717.627.3770 [EMAIL PROTECTED] http://www.dlasys.net fax: 1.253.369.9244 Cell: 1.717.587.7774 Over 25 years' experience in platforms, languages, and technologies too numerous to list.
