CCS/LAUNCHXL-CC2640R2: Does CCS show in which file or line an error exists?

Part Number: LAUNCHXL-CC2640R2
Other Parts Discussed in Thread: TEST2, CC2640R2F

Tool/software: Code Composer Studio

New to CCS. I just created a new project with default settings. I didn't write any code or do anything, just have the template main with return 0.

When I tried to compile I get the following error:

undefined first referenced

symbol in file
--------- ----------------
ResetISR

error #10234-D: unresolved symbols remain
warning #10062-D: entry-point symbol "ResetISR" undefined
error #10010: errors encountered during linking; "test2.out" not built

but it doesn't tell me what file or line the error is found and Find just searches the current active file.

How do I find this symbol or error?

thanks

This is a linker error, which is generally not as helpful as your standard compiler errors which will tell you which line and file cause the problem, and even put a helpful little 'x' beside the line.

How did you create the project? Did you import a blank project from resource explorer?

ti wireless parts need a lot of behind the scenes glue to keep things going. If you just said "create project" in CCS, there is usually not enough there to work. You need to import a CC2640R2 project from resource explorer.

I just tried the "Create Project" wizard and got the same error.

Try this:

use view->resource explorer
choose the CC2540R2 as your board
choose the SimpleLink C2640R2 SDK
choose examples->development tools->cc2640R2
choose TiDrivers->pwmled2->NoRTOS->CCS Compiler->pwmled2

Then click the little CCS symbol to install it in your workspace.

Keith is correct. Line numbers are often mentioned for compiler errors, but not so for linker errors.

As Keith surmised, it sounds like you are working with a new project from scratch for the CC2640R2 and missing some of the initialization files needed which define that function. It is strongly encouraged to first start with the SimpleLink SDK examples. This is in the intended starting point:

Thanks, feel better knowing it's not the IDE.

I actually did start by loading an SDK example like a simple BLE peripheral but they never let me build. The project loads fine, but all the build options are grayed out. What am I missing?

Thanks

Can you provide a screenshot?

Hi Ki,

Here's a screenshot. There was no debug configuration, so I just accepted the default device which seems correct CC2640R2F.ccxml for the Launchpad CC2640R2F. Each time I try to start or stop it creates another new configuration and I can only set break points with the menu, not by clicking on the border and it ignores them anyway. I'm obviously not doing this right.

Sorry for all these noobie questions. Think I'll just have to break down and go through the CCS manual.

In the Project Explorer, can you select the "simple_peripheral" node in the Project Explorer?

Hi Ki,

Hey sorry. I screwed the configuration up so I just removed the project and now it won't reload (something about missing meta-data). I tried loading a fresh example and that was DOA also. I've been coding for 20 years, just don't understand the settings here, though I've used Eclipse many times with little trouble. Is there a basic step by step guide for idiots :)

thanks

oh, sounds like the project may have gotten corrupted.

I would recommend starting from scratch and follow this workshop:

http://dev.ti.com/tirex/#/?link=Development%20Tools%2FIntegrated%20Development%20Environments%2FCode%20Composer%20Studio%2FGeneral%20and%20IDE%2FTraining%2FWorkshops%2FSimpleLink%20Fundamentals%20Workshop%20for%20CCS

And start for scratch - restart CCS using a brand new (empty) workspace folder and follow the workshop (do not use Simple mode).

Thanks

Almost had one... the Simple Broadcaster loaded great allowing me to build successfully, but when I went to debug I got the error shown in the attached screenshot.

Ki,

Ok, please forget the last post with the Broadcaster. I'll read through the link you sent, looks like a good reference.

Thanks!

Hi Ki,

I tried running through the guide, but kept running into problems at multiple points, mostly files missing. So I just started looking for the simplest projects I could import. When I do, build almost always fails with the missing symbols error as shown in the attached screen shot.

Can you help me get this one to build successfully?

Thanks

Where did you access the heart_rate example? I can't seem to find it in the SDK.
