hello, I´m developing under Linux 2.6.10 on the Atmel At91RM9200EK Evaluation Kit. Now I want to bring up U-Boot 1.1.2 on the external Dataflash (AT45DB642). I have a running (uncompressed!) U-Boot 1.1.2 on my parallel flash (AT49BV6416), but I can´t erase the externel dataflash. Do I need the nand utility in my u-boot commands? Which settings are recommended in which header files to get my external flash working?

any help would be appreciated, regards Sascha Dikhoff
