Hallo Warren,
yes, for my opinion the UART console should work similar to LAN/USB but in my case it doesn't. The UART port seems to echo something, due to that, I guess the HW-interface and config setting should work so far and the framework is receiving chars.
I couldn't find any upload possibilty here, otherwise I've shared my very small project with you, may be it's only short look from your side necessary to see were the fault is.
An other question regarding the 30 seconds Off-time: can I disable this sleep-state or how can I avoid that? Is that behavior only enabled if the UART is used with a console framework or generally?
Thanks and regards
Ralph
