Some compiler warnings to deal with: speed.c: In function 'get_sys_info': speed.c:184:4: warning: implicit declaration of function 'get_board_ddr_clk' speed.c: In function 'get_sys_info': speed.c:184:4: warning: implicit declaration of function 'get_board_ddr_clk' Do you want 'CONFIG_FSL_DDR_INTERACTIVE' turned on by default? interactive.c: In function 'fsl_ddr_interactive': interactive.c:1357:15: warning: variable 'len' set but not used [-Wunused-but-set-variable] I'll look at this one. - k _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
