Hi
Actually there is no issue with DCE/DTE.
On the Apalis iMX6 the SOC must use the UART in DTE mode to have the correct pinout. Our BSPs configure the UARTs and the pinmuxing that way.
So the UART pins of either Apalis iMX6 and Apalis T30 connector have the same meaning.

P.S. Apalis iMX6 V1.0 modules were different and required the BSPs to configure the UARTs in DCE mode. IIRC there were no Apalis iMX6 IT with the V1.0 layout.
P:P.S Would it be otherwise the RS232 transceivers on the Ixora would not be happy with at least one of the module types.
