I have tried different combinations of -S and -R options to dtc, but nothing helps: dtc -S 2000 -R 2000 -f of-tmcu.dts -O asm > of-tmcu.S
-S 2000 may be too small, I found I needed -S 3000. If you run dtc without the -S option and add in a verbose/info option(?), dtc will tell you how big your blob is without any padding. Obviously, you need to pad it.
yes, that was it. Increasing to -S 0x4000 makes it work. I was noted this when producing a dtb, I got a warning. The asm version does not warn when the *.S is too small.
