Free run of program on M52235 not possible

Hello,

first of all thank you for this great tool-chain that is so easy to use!
Great work.

I just have one question that I am stuck with a bit. So far it works
perfectly running the software using the debugger. But for some reason, it
does not start when I remove the BDM_EN jumper and reset the board. Am I
missing something here?

I compile the software using:
m68k-elf-gcc -O0 -g3 -Wall -c -fmessage-length=0 -mcpu=52235 -omain.o main.c

And then link it with:
m68k-elf-gcc -Tm52235evb-rom.ld -Wl,-Map=m5223demo_embetter.map,--cref -o"ma
in.elf" main.o

Stepping with the debugger works, my software runs. I assume that the same
software should also run, when the BDM_EN jumper is off. Or am I wrong?

Best regards
Nathan Braun
