I took the code from that new one. I am just starting. My first task
was to port to some devices I have and have a binary to work with. One
thing that I found annoying was that the makefiles do not seem to know
about the fact that the compiler may be a 64 bit compiler.
I have several uc3c0512 and uc3c1512 plus an evaluation board.
The evaluation board for the uc3b0256es has very few features, not
quite as fancy as the one for the automotive part.
I have not looked at the non-aligned access bugs yet but will do in
time. First I have to have something that I can debug on one of my
evaluation boards.
On the subject, the alignment is for word or dword access. You cannot
access a word in the middle, you will get a trap interrupt. Byte
access shouldn't be an issue.
In which case are you having the issue with non alignment? so I will
know which function to look at.

PC relative word loads aren't aligned automatically, and due to the
variable instruction length such an instruction might end up on a
halfword boundary. I have no clue how to fix it in a simple way. LDDPC
has a very small allowable offset
