Hmmm.. that's weird. You should never get a truncation error linking
minimum.exe.
It should always fit within the BSP's memory and not have any issues with
branches
or calls needing fixup.

Unless the wrong type of branch/jump/call instruction is used at
start.S:86, I have
no idea.If it's a form that assumes a short distance to the destination but
is going
to a symbol outside start.S and thus could be further.
