TMS320F28027: Unable to Build Project. New to TI microcontrollers and Code Composer Studio.

Hi,

Did you install latest TI Code Composer Studio and C2000Ware SDK?

If you have installed, then try importing any example for see if you can build it.

C:/ti/c2000/C2000Ware_4_01_00_00/device_support/f2802x/examples/structs/gpio_toggle

Please refer to this workshop, which walks through the steps needed to get started:

Thanks & Regards,

Santosh

Thank you for quick response sir
I have tried that as well. That builds.

Hence I decided to build my project on that only.

When i add other header and source files and build at every step just to be sure, it builds without an issue.

But the moment I add the i2c.c file, i get 11 errors. The errors being linker errors.

What is CCS version and what is C2000Ware version you are using?

Do not add the file, rather import the project. I just tried the i2c example, and it builds well.

C:/ti/c2000/C2000Ware_4_01_00_00/device_support/f2802x/examples/structs/i2c_eeprom

ccs v12 and ccs ware 4.01.

I imported sample projects and then built my code over it.

When I say I added files, I mean added additional files. The files relevant to my project.

I have removed i2c.c from my build.

In this screenshot, I have kept the file and I am getting such an error.

Hi,

I am still not sure what is the issue?  Let me confirm, you tried to import example project from C2000Ware 4.01.00.00. You can build is properly without any issue. Then you are trying to add your file into the example project you imported and you are encountering linker error, is that correct?

or you are creating your own project from scratch and running into this error?

Also, send the error in console log, it has better error description.

Yes correct. I used the sample project as a base. Not creating it from scratch. And now i am facing an error.

Okay Here is the extract from the console log.

You will need to adjust some sections and it does not fit into the memory.

Please go through this page:

https://software-dl.ti.com/ccs/esd/documents/sdto_cgt_Linker-Command-File-Primer.html

This page explains how to modify the linker command file so that section can go into multiple memory section.

Okay I will give this a try and post any update here.
