Link Error in Timer Sample program - timer_m52259evb.mcp

[lel_chen]

Hi,

         In the sample program for timer[timer_m52259evb.mcp], I face the following linker errors:

-------------------------------------------------------------

Link Error: Undefined: "_timer_cancel"
Referenced from "main_task" in main.c
Link Error: Undefined: "_timer_create_component"
Referenced from "main_task" in main.c
Link Error: Undefined: "_timer_start_periodic_at_ticks"
Referenced from "main_task" in main.c
-------------------------------------------------------------

The header file <timer.h> has been included.

Is it because of any issue in the linking order of files?

How can I resolve this issue?  Kindly help.

Thanks,

Chen

Hello

- Which version of CodeWarrior are you using?
To retrieve that info:
   - Start CodeWarrior 
   - Select Help -> About Freescale CodeWarrior
   - Click on "Install Products"
   - CodeWarrior version used is displayed on top in the Installed Products dialog.

Where did you find the timer example project?

Hi,

      The version of CodeWarrior is as given below:

"CodeWarrior Development Studio for microcontrollers V6.2 Release, build 8127"

I got hold of the timer example program from MQX download in:  

 "..\Freescale\Freescale MQX 3.2\mqx\examples\timer"

Kindly help,

Thanks,

Chen

Hello

Apparently you are not using the appropriate tool chain.

"CodeWarrior Development Studio for microcontrollers V6... " only support Coldfire V1 MCUs (MCP51xx).

If you want to use 52259 you need to use (download)

"CodeWarrior Development Studio for ColdFire Architectures V7.1".

This can be downloaded from here.

I hope this helps.

Hi,

      I installed the following version of Codewarrior :

CodeWarrior Development Studio for Coldfire Architectures Version 7.1.1a Patch, Build 9

and tried the sample program again. Still, Im facing the same linker error.

The MQX version used is MQX3.2

Is it due to any settings in Codewarrior?

Kindly help.

Thanks,

Chen

OK

If the issue arises while building a MQX demo, I would recommend you post your question to the MQX forum.
