CCS/EVMK2G: Add GPIO functionality to included SPI arm test project

Jorg Jorgsen

Part Number: EVMK2G

Tool/software: Code Composer Studio

Hello,

I’m having trouble adding/using additional GPIO LLD functionality to a bundled SPI test project.

I’m working on the EVMK2G and am trying to attach to it to an ADC that requires a conversion control signal to trigger a reading. I chose to start with the included project ”SPI_BasicExample_evmK2G_arm_TestProject”. I modified the project to use SPI0 on the serial expansion header (J12) and verified that I have clock and data coming out (from the EVM to the peripheral) as expected. I intend to use GPIO1_47 (SOC_ECAP1_IN_PWN1_OUT / serial expansion header pin 42) to trigger the conversion on the ADC.

I keep running into issues where structs and function calls are flagged by the linker for being an undefined reference despite having the file(s) containing the struct/function implementation included in the project

I added the same #include files that are in main_led_blink.c from the project “GPIO_LedBlink_evmK2G_armTestProject”. Since the project is in a different relative location, I also tried #3 and #4 as absolute paths.
1. #include <ti/drv/gpio/GPIO.h>
2. #include <ti/drv/gpio/soc/GPIO_soc.h>
3. #include "ti/drv/gpio/test/led_blink/src/GPIO_log.h"
4. #include "ti/drv/gpio/test/led_blink/src/GPIO_board.h"
5. I added the project “GPIO_LedBlink_evmK2G_armTestProject” as a dependency to my SPI project. Right-click project -> build -> dependencies -> add… -> GPIO_LedBlink_evmK2G_armTestProject
6. I added .h and .c files to the project Right_click project name -> Add Files . . . -> Link to files, create link relative to PDK_INSTALL_PATH (just like the other files in the project).
7. I noticed some differences in the .cfg files (gpio_arm.cfg and spi_arm.cfg) so I tried to incorporate those into spi_arm.cfg:

/* Load the spi package */

var Spi = xdc.loadPackage('ti.drv.spi');

Spi.Settings.enableProfiling = true;

Spi.Settings.socType = devType;

var Gpio = xdc.loadPackage('ti.drv.gpio');//added

Gpio.Settings.enableProfiling = true;

Gpio.Settings.socType = devType;

…

var peripheralBaseAddrs = [

{ base: 0x4ae00000, size: 0x00100000 }, // PRM

{ base: 0x02530C00, size: 0x00000400 }, // UART 0 regs

{ base: 0x02531000, size: 0x00000400 }, // UART 1 regs

{ base: 0x21805400, size: 0x00000800 } // SPI 0/1/2/3 regs

{ base: 0x02603000, size: 0x00000100 }, // GPIO 0 regs

{ base: 0x0260a000, size: 0x00000100 } // GPIO 1 regs

];

I think that what’s happening here is that I somehow haven’t initialized the GPIO_Config struct meaning there would be no EVMK2G specific drivers for any of the GPIO functions i.e. GPIO_read(), GPIO_write(), GPIO_setCallback() etc.

How do I know exactly what needs to be included in the project to add this functionality?

Jorg,

Can you please copy your entire build log in a text file and share here. It may also be useful to see the full .cfg file that you have.

First thing to try is to see if you can add the file GPIO_soc.c from pdk_k2g_1_0_14\packages\ti\drv\gpio\soc\k2g to the project as all the missing symbols are from that library.

GCC linker can also sometime play tricks during compilation since it doesn`t do a circular search of symbols in the libraries as we have indicated here:

Thank you for your response Rahul,

I tried each of the three workarounds included in the link that you included. They did not solve the issue, however, I would like to share what did in case anybody else finds this page helpful.

Like I said in the post:
> I think that what’s happening here is that I somehow haven’t initialized the GPIO_Config struct meaning there would be no EVMK2G specific drivers for any of the GPIO functions i.e. GPIO_read(), GPIO_write(), GPIO_setCallback() etc.

This assumption was correct.

I did some research in the Processor SDK RTOS (http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_board.html#lld-dependencies) and found the note regarding <drv>_soc.c, here: GPIO_soc.c. It was already added to the project so that wasn’t the issue.

To fix the issue, I had to add GPIO_board.c to the project (PDK_INSTALL_PATH/packages/ti/drv/gpio/test/led_blink/k2g/GPIO_board.c). Contained within this file is the initialization of [an instance of] the struct GPIO_v0_Config.

I did some testing after finding this fix and still found that I had to include the GPIO initialization changes to spi_arm.cfg that I mentioned above. Can you confirm that this is indeed correct and needed?

I included a text file containing spi_arm.cfg and a version of the complete build log for reference.
