That's great. Could you show us the resulting directory structure
(perhaps with a diffstat), as well as the changes to Makefile.am?

Odd. Could you post your test program (or preferably a link to it)?
Perhaps we can look into some of the APIs and see what's wrong.

So if I understand correctly, you were able to make this work by
writing your own code to access the PWM instead of the StarterWare
API? I'd like to see that code as well so we can compare it to
StarterWare's.

Looks good!

I just ran a diff between our sources and the SW version we downloaded
back then, found here:
http://software-dl-1.ti.com/dsps/forms/self_cert_export.html?prod_no=AM335X_StarterWare_02_00_01_01_Setup.bin&ref_url=http://software-dl.ti.com/dsps/dsps_public_sw/am_bu/starterware/latest/
(You need to register a free account to download it).
>From what I saw, most of the changes we did were removing unused code
and fixing mostly cosmetic issues. I'm attaching the diff file so you
can take a look at it. I think one of the most important differences
are the changes in utils/delay.c; Sysdelay was replaced by usleep.
Don't ask me why though, that was a long time ago and it wasn't me who
did it :)
I also saw that SW has a git repository, which seemingly has quite a
few differences from the version we were using. Those seem to be
mostly related to FatFS though.
If I were you, I'd give the old SW code + our patch a shot, then if it
works I'd try to replicate some of the changes on the SW git.
Unfortunately, Marcos and I won't be able to test your progress
because we don't have our BBBs available anymore. We can still review
your code though, and I think Ben has a BBB if you want additional
testing.
On a related note, it would be better if you posted your progress on a
single thread so it's easier to keep track of. No need to open a new
one for each milestone.
