Is an #error in a common omap4/5 file sufficient or does it need to be sooner than that? > Why is thumb mode needed for these boards? Just because of image > size? Basically, yes. Without thumb mode we're very close (and sometimes spilling over) the size limit. Thumb takes us away from that and is a small speed increase (due to smaller sized files). -- Tom _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
