Can you confirm which bit your sprintf has problems with.  Your
suggestion above makes me think it can't cope with %x whereas before I
was assuming it was the variable width formatter (%02) that it was
struggling with.

Have you tried using %hhx instead of %02x?

Got to the lwIP savannah pages
(https://savannah.nongnu.org/projects/lwip/), log in (so create an
account if you don't already have one) and under bugs at the top you
should have a "submit" option.
