How to check debug message from adf_os_print()?

[Xiaoyi Liu]

Sorry for my late response. Thank you so much for the answers.

It seems that I'll need some extra devices to extra the debug message.
I googled serial console, and there are many different kinds of such
devices. Could anyone suggest a model that would work with the
TL_WN821N USB adapter? Thanks!

regards,
eric
