Additional note: tested with current u-boot/master (commit cad04990) on an OpenRD-Client board (which builds Thumb-1 code) using gcc 5.2.1 (which saves and restores r9 in just about any C function, causing arch_setup_gd to fail setting GD): - without this patch, the board fails to boot with an undefined instruction exception. - with this patch, the board boots and functions normally (at least dhcp, tftp, go are working as expected). Amicalement, -- Albert. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
