No particular reason, 0x700 should work as well. As mentioned, this was just a proof of concept to be able to test it. >> +/* dummy defines to keep spl_nand.c happy */ >> +#define CONFIG_CMD_SPL_NAND_OFS 0 >> +#define CONFIG_SYS_NAND_SPL_KERNEL_OFFS 0 >> +#define CONFIG_CMD_SPL_WRITE_SIZE 0 Tom> We should do some real defines here while at it, since the GP EVM has Tom> NAND :) Yes. It's a bit unfortunate that CONFIG_SPL_OS_BOOT is a global setting, so you need all the various falcon boot related defines even if you don't plan on using them. I can try to come up with sensible NAND values, but I don't have a EVM to test. -- Bye, Peter Korsgaard _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
