IWR6843AOP: PINMUX driver for 6843AoP

Part Number: IWR6843AOP

Hi Champs,

I'm working on the mmsdk 3.4.0.3 and IWR6843AoP(rev F). But i can't find the pinmux file for AoP, i think the pin map is different with 6843. Please help to point out where i can find the pinmux file for 6843AoP? Thanks.

  • Hi Allen,

    I will need to confirm this with my team but should have an answer or pinmux solution for you by the end of Tuesday.

  • Hi Allen,

    The same pinmux file pinmux_xwr68xx.h can be used for both IWR6843 ES2.0 and IWR6843AoP ES2.0.

    Hi Akash,

    But the pin index is different between IWR6843 and IWR6843AoP. 

    For example, we use N4 pin as UART RX on IWR6843 but there is no N4 pin on 6843AoP datasheet. 

    /** @name PINN4_PADBD
    * PINN4_PADBD functionality
    */
    /**@{*/
    #define SOC_XWR68XX_PINN4_PADBD 29U
    #define SOC_XWR68XX_PINN4_PADBD_GPIO_15 0U /*< General Purpose IO*/
    #define SOC_XWR68XX_PINN4_PADBD_RS232_RX 1U /*< Debug UART (Operates as Bus Master) - Receive Signal*/
    #define SOC_XWR68XX_PINN4_PADBD_MSS_UARTA_RX 2U /*< Master Subsystem - UART A Receive*/

    Hi Allen,

    Thank you for pointing this out. I believe the differences should be in the pin_mux_config.c and pin_mux_config.h files instead.

    I will email you with a solution.

    Hi, I'm facing the same problem.

    The pinmux file pinmux_xwr68xx.h refers to the 'ABL0161' package. However, the IWR6843AoP is 'ALP180A' package. A lookup table would be useful to quickly compare the ball numbers between this packages. Is there such a thing? or another solution?

    best regards, ruben
