i feel like this is a much more uncommon usage scenario and is more harmful than good to boards, and one which isnt specific to xyzModem. perhaps we need a general tune config which says "prefer malloc over bss" and this creates a set of helper macros which expand either into malloc calls or nothing (since the storage is already in bss). -mike _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
