If I build the SPL using in the embedded_command_shell environment:

~/altera/15/embedded/embedded_command_shell.sh
cd ~/<to-folder-generated-by-BSP editor>/software/spl_bsp
make

I get a working preloader-mkpimage.bin that seems to work with the
u-boot.img generated from the 2016.01 release:

That would seem to indicate at least my quartus/qsys project and the files it
generates are valid and that something is amiss with the terasic board
support code?


BTW - if I set DLEVEL=1 in sequencer.c with the 2016.01-generated SPL I get:

If that's of use to anyone...
