AM5718: Regarding changing serial console uart3 to uart1 in the PDK for AM571x IDK

Part Number: AM5718

Hello Experts,

Currently UART3 is used in the AM571x IDK and we are able to see the console output for the same.

In our custom board we are using UART1 as debug console and need we wanted to check the same in AM571x IDK using PDK.

I changed the PDK code C:\ti\pdk_am57xx_1_0_12\packages\ti\board\src\idkAM571x file: idkAM571x_lld_init

Where a variable instNum = 1 to initialize UART 1.

I am not able to compile the code and see the changes

Below is the error we get for compiling!!

c:\ti\pdk_am57xx_1_0_12\packages\ti\board\src\idkAM571x>gmake am571x
gmake: *** No rule to make target `am571x'. Stop.

How do we compile the code for changes in these files?

Thanks,

Ajit

Ajit,

There are fea steps involved with changing the UART instance on the HW. You need to ensure that pinmux and clock values are updated in the board library in addition to simply switching instance in lld init. Please check similar E2E discussions here:

Thanks Rahul,

I would do the change for pinmux and clock values and update!!

Hi Rahul,

I have followed the steps mentioned in the E2E discussions and please find the screen shot of the changes for AM571x IDK

Hopefully the clock has been configured for UART1

I have changed the PinMux below is the code

/* UART1 - uart1_rxd on B27 - logger */
     {0x17E0, 0xD0000, {0x0, 0, 0}, {0x0, 0, 0}, {0x0, 0, 0}},

/* UART1 - uart1_txd on C26 - logger */
     {0x17E4, 0x90000, {0x0, 0, 0}, {0x0, 0, 0}, {0x0, 0, 0}},

I don't understand why this portion of code is not getting compiled!!
When i try to compile with below command

c:\ti\pdk_am57xx_1_0_12\packages\ti\board\diag>gmake idkAM571x

Ajit,

You are invoking the build inside diagnostics folder. You need to rebuild the board library before you rebuild the diagnostics.

To rebuild board library, go to top level PDK packages folder and rebuild the board library:

cd pdk_am57xx_x_x_xx\packages
// Optional to do targeted build for AM571x IDK
set LIMIT_BOARDS=idkAM571x
gmake board_lib

Hope this helps.

Regards,
Rahul

PS: It is recommended to use pinmux tool to update the SOC pin setting .Additional steps for board porting are described here:

Thanks Rahul,

I was able to build the board_lib files

I am new to the TI PDK environment, hence would like to start with configuring and using just UART1 in AM571x IDK.

Also i have gone through the procedure mentioned for addition of custom board as mentioned in link.

Facing an error in pinmux tool, can you help me resolve it!!

Thanks Rahul for the support!!

Was able to resolve the issue and get the output UART1 in IDK board
