Follow-up Comment #7, bug #42633 (project lwip):
It is not "rare" to have a 16-bit word (not "byte"), particularly on 16-bit
DSPs, and many of them (since they are DSPs not general processors and so they
are designed to handle DSP tasks not general software) don't support byte
operations.
So:
* If your problem lies on your DSP code, I'm afraid you'll have to fix it
yourself, or ask TI for support.
* In lwIP code, you have many different checksum algorithms to try, you might
want to test them and see if someone does the trick.
* You also have the option to offload the checksum calculation to your chip,
check you are configuring lwIP to behave accordingly.
* There is also a thread in one of the lists regarding the checksum algorithms
and one particular bug, you might want to search for it
* You might want to check the comments for bug #33672 and bug #36153
