06:14 <_florent_> sensille: The stub is a fake UART: you'll still have the register, be able to write to the register from software, but it will not generate anything on TX. You'll also never receive anything on RX.

06:15 <_florent_> sensille: That's just a convenient way to disable the UART in the SoC and still execute the same software

06:16 <sensille> _florent_: thanks, so as expected. it's what i was searching for
