You are bringing in the full malloc(). Try adding: CONFIG_SPL_SYS_MALLOC_SIMPLE=y to your defconfig. The should cut the size increment to just under 5KB. That is still a lot. Are you able to use Thumb on your board? Regards, Simon _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
