CCS/TMS320C6748: Ti RTOS HWI creation

Tool/software: Code Composer Studio

I have CCS v6 installed on PC and have been using it for almost 4 years for my (commercial) projects using CSL.

Now I am experimenting with TI RTOS to learn and maybe possibly develop projects in future.

I am going through the TI_RTOS_Kernel_Workshop_Student_Guide_rev4.00 training document which is based on CCS v6.

I did a lot reading on XDC tools and TI RTOS.

I created a simple project RTSC project with XDCtools ver 3.320.0.06_core and Sys/Bios version 6.46.6.00.

I want to create a HWI thread as explained in the training document. I added HWI service from Sys/Bios Scheduling lists.

I am trying to add an instance of HWI thread. In the HWI Module settings, I selected Add the portable Hwi management module to my configuration.

I am trying to fill Handle, Isr function, Interrupt number in the Instance Settings. I fill these fields with the values HWI_TIMER0, legToggleHwi, 5 respectively.

I save the configuration and after saving these fields revert back to N/A, null, null.

So I cannot configure the HWI instance at all.

I also get the error : XDC runtime error: too many arguments app.cfg /blink_C6000_BIOS_2 Configuration Validation XDCTools Configuration Marker

What could be the reason for this.

Best regards

Hi Izzet,

Can you include a snapshot of what you are trying to add? Also, can you attach the whole .cfg file also?

Hi Todd

When I opened the project again, I see that .cfg file is updated. But I do not see that on the outline view.

Thanks

Hi Izzet,

Yea, the .cfg looks like it was updated. I see the following near the bottom

var hwi0Params = new Hwi.Params();
hwi0Params.instance.name = "hwi0";
Program.global.hwi0 = Hwi.create(5, "&ledToggleHwi", hwi0Params);

I tried opening the .cfg in a newer CCS and it looks fine. I'll ping someone to see if there are any known issues with the older CCS/XDCtools. For now, can you just edit the .cfg as a text file (right-click in CCS and open as a text file). Starting in CCS 8.? we've actually changed the default in CCS to open the .cfg as a text file.

Does the Hwi work as expected?

Hi Todd

I modified eventId as hwi0Params.eventId = 64; manually. Then it builds and works.

The main issue to understand is that GUI does not seem to work for configuring thread instance options.

It looks like a kind of mismatch between XDC tools and CCSv6.

This is good enough for me.

But I think I need to switch CCSv8.

Best regards

Izzet
