Starterware/PROCESSOR-SDK-AM437X: Custom board library

Florian Kaiser

Part Number: PROCESSOR-SDK-AM437X
Other Parts Discussed in Thread: AM4377

Tool/software: Starterware

Hello,

I try to make generate a new board library for our custom board.

We use the AM4377 soc and tested the application with the idkAM437x Evaluation kit.

First of all I tried to init some GPIO Pins, and I found this Manual:

www.ti.com/.../sprac32.pdf

Working fine, the GPIO Pins do what I expected.

But the Pins I need to use in our custom board create a short cirsuit in the idkAM437x Evaluation board. So what I want now is a new device which I can select in the CCS7 Project properties. So all hardware Pins are defined and initialized just with using this device. If I just Change the device back to idkAM437x the Evaluation board will not light up. 

I found this Manual:

processors.wiki.ti.com/.../Adding_Custom_Board_Library_Target_to_Processor_SDK_RTOS_makefiles

At first I just want a copy of the idkAm437x with the Name "AM4377_ECP5_Board". Only the Name is different, the code and all Settings are still the same.

But if I try to compile the custom board I only got Errors.

I searched for the error and found this post here:

e2e.ti.com/.../610956

As I understand, I just use the first Manual and that's it.

Is it not possible to add a device as I want?

In the attachment I added the changed board files and the Output of my compile triesCustomBoardTest.zip

Can someone tell me what I have forgotten?

Kind regards

Florian Kaiser

    Hi,

    Sorry for the late response! I looked at your build log:

    The first error comes from compiling this source code:

    AM4377_ECP5_Board_ethernet_config.c:99:9: error: 'GPIO_DIR

    _OUTPUT' undeclared here (not in a function)

    If you search 'GPIO_DIR_OUTPUT' it is declared in CSL code <ti/csl/src/ip/gpio/V1/gpio_v2.h>. Then looked at your AM4377_ECP5_Board_ethernet_config.c, line 6: #include <ti/csl/csl_gpio.h>. So, do you have this in the include path:

    -IC:/ti/gcc-arm-none-eabi-4_9-2015q3/arm-none-eabi/include -I. -Isrc -I

    Yes, it has. Then why it can't find it: open the ti/csl/csl_gpio.h. You can see:

    #elif defined (SOC_AM335x) || defined (SOC_AM437x)
    #include <ti/csl/src/ip/gpio/V1/gpio_v2.h>

    Then, in you pre-defined symbol, do you have SOC_AM437x?

    No, you don't have. This is the problem.

    Yous next errors came from GPIO functions like:  GPIODebounceFuncControl(). They are defined in <ti/csl/src/ip/gpio/V1/gpio_v2.h> as well. The same issue the header file is not included. You need a -DSOC_AM437x 

    Hope this explains the methods how do you debug the build error and fix it.
