Trouble Setting Breakpoint (auto run)

Hi,

I would like you to go through these docs for clarification on CCS breakpoints:

http://processors.wiki.ti.com/index.php/Software_Breakpoints_in_the_IDE

http://processors.wiki.ti.com/index.php/How_Do_Breakpoints_Work

Regards,

Hey,

thanks, I've gone through them.

But my problem isn't actually to set breakspoints, my problem is that I can't debug because it doesn't get to the start of my main.

And that just happens if I add 2 more configurations for other leds, the same functions which work when I debug with only one led...

Very weird, this shouldn't happen. I hope TI employee solves your issue soon; till then keep trying.

Regards,

Gautam

Hi Stefan,

Did you try disabling the auto-run option? The error is confusing... it is actually complaining that it cannot remove the breakpoint it set at main once it reaches it.

Thanks

Hi,

yes I tried, but it didn't help....

It's very weird, every single led works perfect (it's a RGB led), but if I add the setup function of another, it get stucked in a infinite loop...

It is indeed a weird problem. I doesn't sound like specifically a tools issue. It could be some memory allocation issue when you add the additional code. Check your linker settings and make sure memory is being allocated correctly. I'm afraid I can't offer much more suggestions since I don't have much knowledge of your application and my knowledge of the HW is limited. You may get more suggestion in the AM3x forums.

<"Trouble Removing Breakpoint with the Action "Finish Auto Run" at 0x4030118c (address of my main)...>

With a AM335x Starter Kit an empty "hello world" CCS project was created for an AM3358 device, with the connection set to "Texas Instruments XDS100v2 USB emulator". As the CCS default AM3358.cmd linker command only contains internal device memories, the program was linked to the 64KB L3 OCMC0 RAM. The first attempt to load and run a program after reset hang, and the second attempt worked.

The default target configuration for the AM3358 created by CCS didn't have a GEL initialization script for the Cortex-A8.

The GEL initialization script for the CortexA8 was set to ..\..\emulation\boards\sk_am3358\gel\AM3358_StarterKit.gel to match my hardware, which caused CCS to initialize the device upon connection and made the program load and run work the first time after a device reset.

In your project in the target configuration for the CortexA8 is the initialization script set to ..\..\emulation\boards\ice_am3359\gel\TMDXICE3359.gel to cause CCS to initialize the AM3359 ICE Board?

I set the initialization script is to this gel file.

But it didn't help. I still get this:

Disassembly:

Console:

I'm trying to control one RGB led, so I have to multiplex the right GPIO pin and then enable the output mode of thist pin. Before it I configure the functional clock and do a reset of the GPIO module.

Maybe this helps you...?

I did this setting, but it didn't help.

It always get stucked at this address:

403080e4:   EAFFFFFE B               0x403080E4

and shows that error:

CortxA8: Trouble Removing Breakpoint with the Action "Finish Auto Run" at 0x4030118c: (Error -1066 @ 0x3332) Unable to set requested breakpoint in memory. Verify that the breakpoint address is in writable memory. (Emulation package 5.1.73.0)

To control one EtherCAT led, it's necessary to swith the appropriate GPIO pin. At first, the functional clock of GPIO module has to be switched on and i do module reset. Then I have to multiplex the right pin and to enable its output mode.

This is my program.

Maybe that helps you...?

Could something be wrong with my gel file??

I found a thread where someone had the same error which was located in the gel file, there was a false implementation in the "reset" function. But he had a different device than me....

Luna, 

Finally I could sove my problem. 

The gel file coming with the CCS5 for my DSP generation (F28335) disables by default the XINTF. Mine is locate in

ccs5_2\ccsv5\ccs_base\emulation\gel

You can edit and uncomment the following line

OnReset(int nErrorCode)
{
 ..

XINTF_Enable(); /* Uncomment to enable XINTF on Reset */
}

Hope it will work with you too

Stefan - Have you also posted your questions on the AM3x forums? The folks there are more knowledgeable with regards to the target itself.

Not yet...

Thank you for the hint, I'll post it there!

Kind regards

Stefan,

for some reason your post in AM3x forum disappeared. Is the issue solved?

Regards.

No, but I added 2 pictures of my screens and now it has to be checked form anyone...
