Not able to load program on DSP of Beagleboard.

I thought of mentioning few more this too.

When I disconnect and try to reconnect I am not able to. I get the following error message

Error connecting to the target:

Error 0x80001260/-1060

Fatal Error during: Execution, Initialization, OCS, Target, 

An unknown error prevented the emulator from accessing the processor

in a timely fashion.

It is recommended to RESET EMULATOR.  This will disconnect each 

target from the emulator.  The targets should then be power cycled

or hard reset followed by an emureset and reconnect to each target.

Thanks,

Hi Pramod,

What gel files are you using (if any)? I use the ones in: <INSTALL DIR>\ccsv4\emulation\boards\omap35xx_3430\gel for ARM and DSP with good success. I am able to load code at that address and connect/disconnect work well.

Hi Ki,

I first used ' \emulation\gel\omap3430_c64plus.gel' and '\emulation\gel\omap3430_cortexA.gel' but was not able to connect to the board. I also tried setting configuration for Mistral, that didnot work too. Later I removed all the .gel files. Let me describe the procedure I followed and my setup environment.

OMAP3530_XDS510USB_0/6400PLUS_0

Error connecting to the target:

Error 0x80000244/-1178

Fatal Error during: Register, Initialization, OCS, 

The target does not have a CPU clock.

Trouble Setting Breakpoint with the Action "Remain Halted" at 0x82802334:

Error 0x0000000A/-1202

Error during: Memory, Break Point, 

CPU pipeline is stalled and the CPU is 'not ready'. This means

that the CPU has performed an access which has not

completed, and the CPU is waiting. The target may need to be

reset. The user can choose 'Yes' to force the CPU to be 'ready'.

When this is done, the user will have the ability to examine

the target memory and registers to determine the cause of the

CPU stall. If CPU hang is caused by application and it has been

forced to be 'ready', the CPU should not be run without a reset.

  Yes - force CPU ready (might corrupt the code)

  Disconnect - disconnect CCS so that it can be reset

  Retry - attempt the command again

Trouble Halting Target CPU:

Error 0x00001024/-1137

Error during: Register, Execution, Target, 

It appears that the target is being held in reset.  This may be

due to Wait-In-Reset (WIR) configuration set by the EMU0=0

and EMU1=1 pin settings.  If this is the case, DISCONNECT

all CONNECTED devices including icepick and then select

RETRY to clear the WIR configuration.

If this is a multi-core system, the master CPU may not be

releasing the DSP/MCU from reset.  Please check your

configuration in CC_setup and/or your GEL file to ensure that

nothing is blocking the DSP/MCU from being released from reset

 I am using CCS  Version: 4.0.1.01001 and XDS510 USB PLUS. I have selected connection as 'Spectrum Digital XDS510USB Emulator' and Device as 'OMAP3530_XDS510USB'.

4.0.1 is a fairly old version. The selection for  your Device I do not see in my version. Could you upgrade to the latest version (4.1.2)? You can get to it using the Update manager (Help->Software Updates). That way at least  we are both on the same version of CCS as I try to debug your issue.

After that, recreate your configuration. Use 'OMAP3530' for the device and try using the gel files I mentioned previously.

Hi Ki,

Thanks for the prompt reply. I updated my CCS to  Version: 4.1.2.00027 . I selected the gel file as you mentioned from <ccs4 install dir>/emulation/board/gel and selected sdomap35xx_C64plus.gel for DSP. I did not have any other option for .gel file for DSP. And then selected Beagle_Omap35xx_CortexA8.gel for ARM. I did have other options but this looked better choice as I am working on Beagleboard. I had selected OMAP3530 as device instead of OMAP3530_XDS510USB. When I click on Debug Active Project, I get following error

Exception occurred during lunch. 

Reason:

Failed to load program 'cvDFT.out' on any of the targets.

Reason: The target OMAP3530_XDS510USB_0/6400PLUS_0 could not be found.

Hi Ki,

Even I put the DSP out of reset as said in http://processors.wiki.ti.com/index.php/Debugging_the_DSP_side_of_a_DSPLink_application_on_OMAP_using_CCS, I am not able to connect and the debug session does not start.

Those are the files I used also.

Could you delete your existing ccxml file and create a new one from scratch? Also try deleting the existing Debug launches for the project. See slide 57 of: http://processors.wiki.ti.com/images/0/09/CCSv4_Tips_%26_Tricks.pdf

FYI - since you are using a multi-core device, Debug Active Project will try to connect, load and run to the first CPU in the scan chain - I think the DSP here (which is what you want). But you may want to look at the CCSv4 multi-core wiki for future reference: http://processors.wiki.ti.com/index.php/Multi-Core_Debug_with_CCS

Thanks

Hi Ki,

 I deleted the existing ccxml file and created a new file. I also deleted all the Debug lunches for all the projects. My configuration were still same as mentioned above. When I tried to Debug Active Project. I go following errror message.

Error connecting to the target:

Error 0x80000244/-1178

Fatal Error during: Register, Initialization, OCS, 

The target does not have a CPU clock.

I then, though of removing the DSP out of reset as mentioned on the link I provided on my previous post.

Yes I got the same error until I released the DSP out of reset. After I did so, I was able to connect.

When I tried to connect after executing lpmOFF and lpmON( I executed this since I had already  ran some application on DSP), I got following error.

So if I understand correctly, you were able to connect to the DSP and execute some applications? And then you disconnected and tried reconnecting and get the error?

Actually, I think you mean that the ARM loaded some code to the DSP and ran it. Then you are trying to connect to the DSP for debugging and hit the error?

Hi Ki,

>So if I understand correctly, you were able to connect to the DSP and execute some applications? And then you disconnected and tried reconnecting and get the error?

No, I did this from my console on my host system, which is connected to the beagleboard.

Hi Ki,

I restarted everyting and first kept the DSP out of reset and then I was able to connect to the DSP, but when I tried to load my program, it gives following error.

Pramod,

Could you provide your exact use case? Basically provide step-by-step instructions on what exactly you are doing (any provide any executables and other sw needed). I've just been playing around with basic connectivity to the DSP and loading some simple files. But I need to copy what you are doing to see if I can reproduce this.

Thanks

Hi Ki,

I am basically trying to expand the FFT example provided in the DSPLib. I have cut-short that example and planning to expand as needed. When I simulate it using 64x+ cycle accurate simulator, its fine. Then I tried to emulate it; there is where I have a problem.

Please find the attached project file.

I am still getting the error when I try to load program.

Pramod,

Thanks for attaching the project. I was able to load it just fine. I must have something different in my environment. All I did was connect to the ARM, execute 'Scripts->OMAP35xx Functions->C64xPlusRelease_FromReset', connect to the DSP and then load the out file. Perhaps it is something that you have flashed on to your board that is causing the issue (sorry I don't have a whole lot of knowledge on the Beagle Board). Otherwise I am using the same CCS version, same emulator, same target config, same gel files and same target board.

Hi Ki,

Thanks for your response and effort. I had never tried to release the dsp from reset using the scripts. I was using DSPLink to do so. 

But still, I tried this way too. Still no result. When I try to connect to the CortexA8 I get the following error. Does this error message has to do anything with my problem? However I am able to control the execution on it. So, I think I have no problem with it. 

Cortex_A8_0: Warning: Error 0x40000002/-1065 Warning during: Memory,  Invalid memory access at 0x00000000  

Cortex_A8_0: GEL: Error while executing OnTargetConnect(): target access failed.

When I run cortexA and then execute the Script ->OMAP35xx Functions-> C64xPlusRelease_FromReset, there is nothing (no message on the console. When I halt the execution of CortexA8 and try to run the Scripts...................., i get following error message and nothing on the console.( I generally get something turned on/off message when I try other functions.)

Error connecting to the target:

Error 0x80000260/-1178

Fatal Error during: Execution, Initialization, OCS, 

The target does not have a CPU clock. 

Is something wrong with my .gel file? Is it possible that I can try with one of yours. If it is, then my e-mail is

ktmpole@hotmail.com

Once again, I would like to thank you for your response even on holiday.

Regards,

Pramod
