IWR1642BOOST: Changing mss logger pin

Hong Kim

Part Number: IWR1642BOOST

Hi,

I want to change mss loger pin from AR_MSS_LOGGER to AR_MISO1.

To do so, just changing PINMUX setup is enough?

Regards,

HONG.

FROM

/* Setup the PINMUX to bring out the UART-3 */
Pinmux_Set_OverrideCtrl(SOC_XWR16XX_PINF14_PADAJ, PINMUX_OUTEN_RETAIN_HW_CTRL, PINMUX_INPEN_RETAIN_HW_CTRL);
Pinmux_Set_FuncSel(SOC_XWR16XX_PINF14_PADAJ, SOC_XWR16XX_PINF14_PADAJ_MSS_UARTB_TX);

TO

/* Setup the PINMUX to bring out the UART-3 */
Pinmux_Set_OverrideCtrl(SOC_XWR16XX_PINF14_PADAJ, PINMUX_OUTEN_RETAIN_HW_CTRL, PINMUX_INPEN_RETAIN_HW_CTRL);
Pinmux_Set_FuncSel(SOC_XWR16XX_PINF14_PADAJ, SOC_XWR16XX_PIND13_PADAD_SPIA_MOSI);

    Hello,

        Along with the pin you need to look at the device resources as well. MSS_LOGGER is a UART pin, it need to be connected to UART capable pin. SPIA_MOSI pin is not UART capable pin and if you expect UART functionality on that pin it would not be possible. 

    Please review the pin muxing table in the datasheet for the relevant UART capable pins.  

    Thanks and regards,
