Using sys/bios mutex example on LM4F232H5QD

Wensan Chou

Hi experts,

I'm trying to be familiar with sys/bios on LM4F232H5QD.

And I just use the example mutex project.

However, while loading program by CCS I got,

"Can't find a source file at "/db/vtree/library/trees/avala/avala-q17x/src/ti/sysbios/family/arm/m3/Hwi.c" 
Locate the file or edit the source lookup path to include its location."

My environment :CCS Version: 5.1.1.00028

XDC tools 3.23.0.32

SYS/BIOS 6.33.0.19

Any experts can help me?

Dear Wensan,

this often occurs as the supplied binaries are compiled on a different machine and therefore contain the wrong debug paths. You can point CCS manually to the same file on your machine. Just check where your Sys/Bios folder is located and follow the path

src/ti/sysbios/family/arm/m3/Hwi.c

Regards.

Hi Quote,

Thanks for your quick response.

Following your description, I locate hwi.c successfully, but I still cannot complete "load program" to M4.

It always halt for unknown reasons.

But I can successfully run the program on LM3S9B96.

Please help again.~

Thanks and Best regards,

Are you using a gel file for the LM4F232H5QD?

WenSan,

Can you be more specific? What are the exact steps you are doing and errors you are getting.

Did you rebuild the application using the LM4 device in the platform?

If not, you're probably trying to run an application that sets the PLLs to 80MHz on a device that only runs 40MHz..

Hi Todd,

Here below is my steps.

(1)create project by CCS and choose SYS/BIOS example mutex

(2)specify RTSC settings.

(3)Compile successfully

(4)Star to debug, however, it has no response and I wonder if "loading program" successfully or not.

(5)then, I push "Suspend"

(6)locate hwi.c as Frank Walzer said

(7)After hwi.c was located, it always stop here, even I push "Run" or "Reload Program"

Hi Alan,

I'm using LM4F232H5QD EVB , and I think it is a 80MHz, right?

We'll try the same experiment locally and report our results.

In the meantime, can you try using the ti.targets.arm.elf.M3 target rather than the ti.targets.arm.elf.M4F target and see if you get better results?

I built the same example using the same settings as you, except that I built with BIOS 6.33.02.31 and XDCtools version 3.23.01.43.

I loaded and ran the resulting application successfully on my LM4F board.

Can you try updating to the same tools and see if you still have the problem?
