Review comment:
@davids5 I posted my answer there:
https://github.com/apache/incubator-nuttx/pull/3169#issuecomment-806616431
So, in summary, for achieving the most standards-compliant and portable code:
- Native integer types (int, unsigned...) **->** Specifiers from `fprintf`
documentation (d, u....)
- https://pubs.opengroup.org/onlinepubs/009695399/functions/fprintf.html
- Fixed width integer types from `stdint.h` (int32_t, uint32_t...) **->**
Specifiers from `inttypes.h` (PRId32, PRIu32)
