Working through TI-RTOS Basic - Lab 1, I'm stuck with finding a file..

'The value of this variable [µs/tick] is determined when the TI-RTOS .cfg file is parsed.'

Where is this file?

Are you talking about this training: training.ti.com/ti-rtos-workshop-series-1-10-welcome

If so, can you give me where in the video you are talking about?

Please note, the solutions zip should be downloadable from the site, but there is currently a problem. We are trying to resolve that.

Hi Todd, Thanks for getting back to me.

All my questions are based on the lab downloaded from:

http://processors.wiki.ti.com/index.php/Category:BluetoothLE

SimpleLink Academy installer for Windows

http://software-dl.ti.com/lprf/simplelink_academy/setup_simplelink_academy_01_03_00_0000.exe

But I will look at your link with intrest

Yours Simon M.

Hi Simon,

Thanks for clearing up my confusion. I've been meaning to look at the SimpleLink Academy! Thanks for stopping me from procrastinating:)

The file name is this case is flash_debug.cfg. This file can be opened as a text file (right-click->Open With->Text Editor) or graphically (double-click or right-click->Open With->XGCONF. The .cfg file is the kernel configuration file. It helps fine turn the kernel to exactly what you want.

Hi Todd,

Thanks for getting back to me again.

That helps.

Looking in

C:\Users\Workroom\workspace_v6_1\TI-RTOS_BasicTask_ST

I see I have two .cfg files, one is the flash_debug.cfg, and the other is rom_release.cfg. the first file I think controls the setup of the debug environment, and the second has

/* 10 us tick period */
Clock.tickPeriod = 10;

which I think is the one that is referred to in the lab?

Am I correct

The rom_release.cfg one is greyed out so it is being excluded from the build. I'm not sure why that file was in the project (but excluded from the build). Does not mention it in the write-up. Please note there can only be one .cfg in a project.

So yes, look at the flash_debug.cfg one.

Hi Todd,
Still can’t get this.
OK, I see the ‘ rom_release.cfg [TI-RTOS]’ is excluded, along with ‘lab1-main-solution.c’.

But how do I add

/* 10 us tick period */
Clock.tickPeriod = 10;

To ‘flash_debug [TI-RTOS]’?

Do I use project explorer?
If so how, or do I edit it with notepad?

And where do I add it?

Is there a guide on this?

Yours as ever
Simon M.

Simon,

You can edit the file as a standard text file. In CCS, you can do right-click and select to Open With->Text Editor (or XDCscript editor if you want nice colors). If you open with XGCONF, you can graphically navigate to the Clock module and set it there.

Hi Todd,

Thanks again for taking the trouble to help me.

I think I'm getting it, very s-l-o-w-l-y though.

The XGCONF is built into CCS, and what you are presented with when you double click on any .cfg file. Have I got this correct?

If so, I think my question is really how do I use this tool to add the clock.period?

Do I have to edit the script directly?

Yours Simon M.

P.S. I can only thing that the ‘rom_release.cfg’ & ‘lab1-main-solution.c ‘are included as solutions to help?

Hi Simon,

You can navigate graphically. For example I selected the Clock module on the right and then modified the Tick period. The "cfg Script" window shows what is changing in the file. It is more to learn what the text settings are in case. We don't recommend doing things graphically and then popping into the "cfg Script" and editing because you might lose something. If you want to do the text, open the file as a text file.

Thanks Todd, just the sort of answer I wanted, a clear 'how 2', and why..

Thanks again
