Hi can someone explain if there is any difference in pyb.sync() and uos.sync() ?

In the docs it says they synchronize all filesystems.

Do they use the same function?

Yep - they are identical.

pyb.sync: https://github.com/micropython/micropyt ... pyb.c#L188
uos.sync: https://github.com/micropython/micropyt ... uos.c#L162

Both refer to mod_os_sync_obj, which is implemented here: https://github.com/micropython/micropyt ... .c#L86-L95
