Starting barebox itself from NOR has nothing to do with the NOR subsystem. I'm not familiar with the mini2440, so I can't tell what you have to do to start barebox from NOR. However, adding a NOR device to barebox (so that you can access NOR flash from within babreox) is trivial, just add the following: add_cfi_flash_device(-1, base_address, size, 0); Sascha -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
