We were using the Janus with the Overo Ironstorm-P. The serial port on the Janus was working fine until we were forced to migrate to the Ironstorm-Y. Now we're not getting serial messages through the J5 connector.
Re: Janus serial port doesn't work with Ironstorm-Y
The serial console (UART3) did not change so you shouldn't be seeing any difference. Can you describe your setup (board numbers, WO####, maybe some pics) so we can see what's going on? What commands are you using to attach to the serial console?
