Is it usable, too? Yes, I will add it to in v5. > According to the datasheet the SOM expose 7 UARTs, but only the debug > UART is enable. What is the reason for this? So those 7 UARTs are: UART1: console UART2: used by the microphone UART3: used by the resistive touch UART4: used by the ethernet/resistive touch UART5: on J18.4,6,8,10 (used by BT) UART6: on J18.7 and J18.9 (available) UART7: on J18.3 and J18.5 (used by the M33 firmware) I will enable UART6, and add a mention about UART7, something like: /* J18.7, J18.9 */ &lpuart6 { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_uart6>; status = "okay"; }; /* J18.3, J18.5 - used by M33 firmware */ &lpuart7 { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_uart7>; status = "disabled"; }; > Btw the commit log mentions a Wifi (via SDIO?) and audio interface.

I am not sure about that, and I would prefer to study that a bit later on if that's OK :) I can remove it from the commit log as this is misleading as not already supported / tested. Thanks, Mathieu
