You are not talking about u-boot sources in mainline. Linking the DCD together with u-boot is the original development by Freescale. There is no flash_header.S in u-boot. In mainline, an header is added to the binary providing a different image that can be loaded into the storage. See doc/README.imximage. This is consistent in u-boot because other processors use the same approach. > Does anyone have u-boot booting from NAND on mx51? Any repository, or a > patch that might be available? At the moment, NAND is not supported in u-boot mainline for the MX.51. Patches are welcome ;-) Best regards, Stefano Babic -- ===================================================================== DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: +49-8142-66989-0 Fax: +49-8142-66989-80 Email: off...@denx.de ===================================================================== _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
