Hello,

Can one communicate with CC2538EM via USB (e.g. terminal)

P.S. I precise that CC2538EM is alone (without SmartRF06)

Yes, you can create a virtual com port using the USB module on the CC2538 and using the USB connector on the CC2538EM to connect to your PC. The EM is furthermore designed to be able to take power from the USB connector.

In the case of CC2538EM+SmartFR06 I use simple printf commands for program diagnostic.

Will printf work with only CC2538EM ?

Yes.

Please have a look at the software examples for the cc2538.

Hello,

In my project I use Contiki staff (not TI firmware).

What I can state is: CC2538EM (as opposed to CC2538EM + SmartRF06) isn't seen by terminal tools (I use Hterm 0.8.1 beta).

At the same time I'm sure that CC2538EM is powered and works properly (I control its behavior by RF-link with another board).

Regards

Pavel.

Yes, the CC2538 port in Contiki supports USB-CDC (virtual COM port), please see http://processors.wiki.ti.com/index.php/Contiki-6LOWPAN
