commit: https://git.buildroot.net/buildroot/commit/?id=07552de23b95b48412be89ca5c162d8855872206
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

As mentioned in sha2/README, by default, tinydtls uses u_intXX_t data types
for 8 bit, 32 bit, and 64 bit unsigned integer type definitions.  To use
uintXX_t data types as defined by recent ANSI C standards and as included in
the inttypes.h header file, SHA2_USE_INTTYPES_H has to be define at compile
time.
