AM335x Pinmux for DCAN & Wireless

Nitin Singh1
Intellectual 380 points

Hi,

We are working on an application which requires bluetooth, wifi and DCAN of AM335x EVM.

All these interfaces work in different profile i.e profile #0 (BT/Wi-fi) and profile #1 (DCAN), but we want them working at a time.

How can i use these interfaces in one profile? would Pinmux be helpful? I followed below link, but as newbie to this, didn't grasp it at all: http://processors.wiki.ti.com/index.php/AM335x_PSP_User's_Guide#Modifying_Pin_Mux_settings

Please suggest with solutions to this issue? 

Thanks,
Nitin

    Hi Nitin,
     
    On the EVM this would be impossible, since the signals you need are routed through a CPLD on the daugther board. The profiles switch different CPLD configurations. Pinmux will not help here.

    Hi Biser,

    Thanks for replying. I just need to know how can i get BT & DCAN working on EVM simultaneously? I am booting the board with sitara Linux.
    Please update.

    Thanks

    Hi Nitin,
     
    There is a possibility, but you will need to rework your EVM a little. On the Base Board schematics you can see that DCAN1 can be pinmuxed on UART0 CTS and RTS pins. If you trace these two nets (AM335X_UART0_CTSn and AM335X_UART0_RTSn) you will see they come to expansion connector J5 through R213 and R216. On the Daughter Board schematics page 5 the CAN interface is connected through R43 and R44. So you can remove R213, R216 (Base Board) and R43, R44 (Daughter Board) and throw two wires across the two boards. This way you will have your CAN transceiver connected directly to the processor at all times.

    Hi Biser,

                  After making these changes I had following queries with this:

    1- The UART0 Ctsn and Rtsn pins should be changed to DCAN1 TX, RX functionality in softawre correct ? Otherwise that pin will be only acting as UART0 functionality rather than selecting internal dcan module. So please tell whether software changes in linux setup files are necessary?

    2- Is ther any issues of voltage mismatch or any other due to these hardware changes?

    Please see attached files for better reliazation:

    Hi Pramod,
     
    1. The pinmux will probably need to be changed on UART0_CTSn and UART0_RTSn pins (registers conf_uart0_ctsn at address 0x44E1 0968 and conf_uart0_rtsn at 0x44E1 096C). Pin mode should be set to 2.
    2. There shouldn't be any voltage mismatch issues. I have double-checked, voltage levels are 3.3V.

    Hi Biser,

                  First of all Thanks for your quick Support on this as this is very important solution for us.

    I had few queries with this:

    1- I had checked the resistance R213 and R216 at Am335x controller side that is coming on J5. I had traced them correctly on board but my issue is the resistors are of 0603-smd size and that could be difficult for us to solder wire at such small   pad. So alternatively this J5 signals are coming on daughterboard J3 connector 21 and 23 same pins so if we sratch the track of J3 21 and 23 pins and soldering on J5-baseboard 21 and 23 will be fine?

    2- We had checked the software side - You suggested the addresses 0x44E1 0968  and 0x44E1 096C which are in am33xx.h file

    #define AM33XX_CONTROL_PADCONF_UART0_CTSN_OFFSET 0x0968 (base address is added 0x44E1 )

    #define AM33XX_CONTROL_PADCONF_UART0_RTSN_OFFSET 0x096C  (base address is added 0x44E1 )

     is already set to these address so i think no need to change them. or ?

    3- If we do so on UART0 Cts and UART0 Rts handshake pins So will it affect Uart0 operations?can we use UART0 on J12 and J10 DB9?   and so if not we may not have debugg thorugh serial port for Starterware and other applications. So please confirm cts and Rts pins  will affect UART operations?

    Thanks

    Regards,

    Pramod

    Hi Pramod,
     
    1. Yes, you can cut the tracks (if that is what you mean by scratch) on daughter board J3 pins 21 and 23, and solder the wires on base board J5 pins 21 and 23.
    2. The two padconf registers are defined OK, but you will probably need to change the values that are written in them. You need to set the mode bits to 2.
    3. UART0 handshake signals are not connected anywhere else on the base board. If you check the schematics you will see that there are resistors, which are marked as DNI on these lines. Debug UART works perfectly without handshaking - it doesn't use it.

    Hi Biser,

                I  had checked the datasheet (AM335x-and ARm cortex-A8) in that for changing the UART0_Ctsn pad mux configuration  I had following observations

       1- Changing UART0 ctsn and Rtsn offset means making configuartion register changes .....in which it has mentioned

      -------All other register offset addresses not listed in Table 9-10  should be considered as reserved locations and the register contents should not be modified.

    Moreover for DCAN, only 0x644h dcan_raminit     entry found and not for DCAN TX and RX pins

     So is it necessary to change that value.

    2- I had initialized DCAN1 at initialization so through that function it sets pin to mode 2 function , so probably above point can be solved at that stage or still we need to change padconfig values. If yes please tell the values to load?

    Warm Regards,

    Pramod Jagtap

    Hi Pramod,
     
    If you have set UART0_CTSn and UART0_RTSn pin mode to 2, that is enough. Pins are then connected to DCAN1 peripheral.
