CCS/TMS570LS0714: Errors on initializing spi, gio etc [ gio_init ./source/sys_main.obj]

Other Parts Discussed in Thread: HALCOGEN

Tool/software: Code Composer Studio

Hello,

I am having some issue with the initialization of the gio, spi etc. as shown in figure. The errors I have are:

gio_init ./source/sys_main.obj
i2c_init ./source/sys_main.obj
output_high ./source/sys_main.obj
spi_init ./source/sys_main.obj

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "payload_code_TMS.out" not built

What could be?

Hello,

gio_init ./source/sys_main.obj
i2c_init ./source/sys_main.obj
output_high ./source/sys_main.obj
spi_init ./source/sys_main.obj

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "payload_code_TMS.out" not built

error 10234 is a common linker error. Please see the below link for more details and for suggestions on how to resolve it:

https://software-dl.ti.com/ccs/esd/documents/dmed/HTML/10234.html

Basically you need to add the library or object files that define the four symbols in question.

Thanks

I have tried with a sample code and I have the same errors. I have followed this guide leaving the main white:

processors.wiki.ti.com/.../LAUNCHXL2_TMS57012:_Project_0

And I have these errors and using these linker/include:

The linker reports that it has seen a duplicate definition of the main function in both:

source/sys_main.obj, which is from the source/sys_main.c generated by HalCoGen
main.obj, which is from main.c which has been added in the project

The project needs to be changed so that there is only one main function.

https://processors.wiki.ti.com/index.php/LAUNCHXL2_TMS57012:_Project_0#Configure_the_Device_Initialization_Code_with_HalCoGen

That guide explains how to add code into the empty main function in the source/sys_main.c file created by HalCoGen. In that case, removing the main.c source file from the project should remove the linker error for the duplicate definition.

I did it and still, I have errors with .h file. I have linking errors as shown in figure but I have just include the HalCoGen set-up. Why he can't find library he has made?

I am going step by step and the main error I find is on the GPIO, I2C etc initialization, hay it appears if I have all the path included?

Based upon those errors, it appears the GIO, I2C, SPI and FEE drivers are not enabled on the HalCoGen "Driver Enable" tab. If you enable the drivers in HalCoGen and then select "Generate Code" in HalCoGen the source for the drivers should be generated.

Re-building the project in CCS should then compile the drivers.

Thank you, finally I included in HalCoGen the FEE driver and I have changed gio_init(); to gioInit(); (it is defined like this) and it complines, but I have still some error I have forced to work. It is that I have defined:
int SS =spiChipSelect.SPI_CS_0;
using this I have the error #20 identifier spiChipSelect is undefined. But if I go to the spi.h it is defined like this:

enum spiChipSelect
{
SPI_CS_NONE = 0xFFU,
SPI_CS_0 = 0xFEU,
SPI_CS_1 = 0xFDU,
SPI_CS_2 = 0xFBU,
SPI_CS_3 = 0xF7U,
SPI_CS_4 = 0xEFU,
SPI_CS_5 = 0xDFU,
SPI_CS_6 = 0xBFU,
SPI_CS_7 = 0x7FU
};

So I force int SS =0xFEU; and now it works, but I don't understand where is the error.

In C enumerations are not qualified by the type. Try using SPI_CS_0 instead of spiChipSelect.SPI_CS_0

Hello Andrea,

As Chester said, you can use the enumerators in {} as constant.
