RTOS/AM5716: UART3 pinmux

Part Number: AM5716
Other Parts Discussed in Thread: TMDXIDK5718

Tool/software: TI-RTOS

Hello ,

      we designed an new board according our application several months ago. and the uart3 pad of our board is different with the TMDXIDK5718.uart3 of  TMDXIDK5718  is connect to  D27,C28 and  the uart3 of our board is connected to V2,Y1.and right now ,we are using the RTOS samples to test our board, but firstly we have to change the uart3  configure to V2,Y1 so that those samples can runing right.and we using pinmux tool to set the right connect and generate several files, we replace those files but no changed be found. so would you please kind tell me how should I do?

best regards

    Please describe the process that you used to change this setup. I am assuming that you opened the idkAM571x_SR2.0.pinmux from the directory: pdk_am57xx_1_0_xx\packages\ti\board\src\idkAM571x in the pinmux tool and changed the pins from D27. C28 to V2, Y1 and generated the source files BoardPadDelay*.c and BoardPadDelay*.h files and replaced them with the files in the existing board library.

    Did you rebuild the idkAM571x board library and then the application (in that order) ? For the change to take effect, you need to rebuild the board library and have the application link to the newly built board library so that he Board_Init call from the application applies the necessary settings.

    Steps to rebuild the board library :

    cd pdk_am57xx_1_X_Xx\packages
    gmake board_lib LIMIT_SOCS="am571x" LIMIT_BOARDS="idkAM571x"

    The ideal way to confirm would be to look at the CTRL_CORE_PAD registers corresponding to V2 and Y1 to confirm and to make sure that after this change there is no activity on D27 and C28 pins.

    Hope this helps.

    Regards,
    Rahul

    PS: I have noticed a quick diff of the original idkAM571x pinmux files and the modified pinmux files helps to see what the pinmux tool modified to confirm when the software is running. Also, check to make sure the board library build time stamp updates after you rebuild the board library.
