Start Profinet example on Sitara AM3359

Hey Frank,

thanks for this fast answer. Ok if you say i should don't touch the m3, i will do this.

But, when i only start the A8, the processor run, but the processor do nothing! The stackpointer always shows zero!

Or does the programm only run if on RJ45 a subscriber is connectet? Is this what you mean with "the example is of no use" without a profinet controller?

Regards,

Sebastian

Sebastian,

I don't know what you are doing. Obviously you need to load the application code and start if you run this from the debugger. If you start from SDcard this is automatically done. So please see the IA-SDK documentation (the process is the same for all the examples).

And yes, the Profinet device examples really only makes sense if you have a PLC. It is a communication application so you need something to drive the comms... But of course the app will run and wait for comms input. It might even blink a LED...

Regards,

Sebastian,

Please follow the instructions given here to load and debug an application via CCS.

You can also find some info on the Profinet application available in ISDK here

Hey,

thanks for all these answers. But the system still doesn't run!!

I used the instructions and applications you said.

I imported the example.

I built the project.

I create the "Target configuration" und connect the PC succesfully with the board.

After this i loaded the "GEL-File" und made succesfully the initialization.

Then i loaded  the"....out"-file.

At the end of loading the following error is shown:
-----------------------------------------------------------------------------------------------------------

CortxA8: Breakpoint Manager: Retrying with a AET breakpoint

---------------------------------------------------------------------------------------------------------------------------

The A8 is running, but there is no blinking LED on the Sitara!

There are these errors!!!!

I don't start the M3 and a Siemens-PLC is succesfully connected to the board. The PLC run. The Sitara-LED on the "ETH0"-Port is on.

But there is no blinking LED and no communication!

Do you know these problem?

Sebastian

Sebastian,

maybe you should start with a more basic example....

Generally you should not see the emulation errors. If you load a program by default it will run to main() and stop there. Then only when you press run it will start your application on the ARM core. So there is still something wrong with your setup.

What hardware are you using? ICEv1 or V2? Each one has a dedicated GEL.. Also you usually need to do a CPU Reset(HW) before you apply the GEL and load the program.

Regards,

Sebastian,

Please check the "Notes" section of this.

Also, as Frank suggested, make sure you are using the correct GEL file and try executing a basic example(Eg: i2c_led)

Vinesh

Hey,

i tried to do what you say. I delete all projects and start the examples from the beginning.

At first, i imported the i2C_led - example. But when i started the .cfg-file from the example, the following error is showing:

------------------------------------------------------------------------------------------------------------------------------------------------
xdc.tools.configuro: Error: Can't find the platform package 'ti.platforms.evmAM3359'.  TI platforms are no longer shipped as part of XDCtools (C:\ti\xdctools_3_30_01_25_core).  Please ensure you are either using a pre-3.30 version of XDCtools or you have added a product that includes your platform support along the path 'C:/ti/bios_6_35_04_50/packages;C:/ti/ccsv5/ccs_base;C:\ti\xdctools_3_30_01_25_core/packages'.  Check that this path names a directory containing the necessary platform support and that the platform name is properly spelled.    .xdchelp    /i2c_led    line 51    C/C++ Problem
-------------------------------------------------------------------------------------------------------------------------------------------------------

what does this mean? all these directories exist, but i didn't find the file 'ti.platforms.evmAM3359' ! Where should this file be?

---------------------------------------------------------------------------------------------------------------------------

After this, i imported the profinet - example. When i started the .cfg-file from the example, the RTSC-configuration was built sucessfully! But when i build the project, it shows the following errors:

----------------------------------------------------------------------------------------------------------------------------------

gmake: *** No rule to make target `C:/Users/Sebastian/Workspace_TI/protocols/profinet_slave/drivers/iPNDrv.c', needed by `iPNDrv.obj'.

gmake: *** No rule to make target `C:/Users/Sebastian/Workspace_TI/protocols/snmp/drivers/snmp_ndk_interface.c', needed by `snmp/snmp_ndk_interface.obj'.

---------------------------------------------------------------------------------------------------------------------------------------------

These files doen't exist in the "am335x_sysbios_ind_sdk_win32setup_01_01_00_04" software from TI.

I read the "Getting Started Guide" and the "Notes" from Vinesh and did it on the same way! But it doesn't run!!

Have anyone an idea?

Regards,

Sebastian

And yes i use the Sitara V2!

From the logs I understand you are using CCSv6. Please check the software requirements here

Also, I'm not sure why you can't see those files. Please recheck the installation paths.

Regards,
Vinesh

No, i use Code Composer Studio version CCS 5.5.0.00077 !

And i use

• SYSBIOS 6.35.4.50 Real Time Operating System 
• Network Development Kit (NDK) 2.22.3.20

The problem with XDCTOOL was dissolved by using an older version. (Version 3.25.3.72).

The Version "xdctools_3_30_01_25"  creates the errors above!

So now i can build the project and can connect with the sitara ICE V2! But before i load the ".out file", i load the GEL-files. When i start initialization of the GEL files, the following error result:

---------------------------------------------------------------------------------------------------------------------------------

CortxA8: Trouble Writing Memory Block at 0x4c0000e4 on Page 0 of Length 0x4: (Error -1065 @ 0x4C0000E4) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.232.0)

    at AM3359_ICE_Initialization()

--------------------------------------------------------------------------------------------------------------

I try to use a lower TCLK, but without any result!

Do you have an idea?

Regards,

Sebastian

And yes i push the reset button on the board, before initialization of GEL-files!

And i try the "TMDXICE3359.gel" and "TMDXICE3359_v2_1A.gel" files, which were in the GEL-folder in the example-project. Both files deliver this error-log!

Hey Vinesh,

I used "TMDXICE3359_v2_1A.gel " and yes i  used "Texas Instruments XDS100v2 USB Emulator" too.

And i tryed different examples. (profinet, led, ethercat )

I don't use a SD-card. I only debug over CCS. Is this the problem?

Regards,

Sebastian

Sebastian,

Follow these steps

• Launch Target configuration(XDS100v2)
• Connect to CortexA8
• Put a "Hardware Breakpoint" at 0x402f_0400 or 0x0800_0000(Depending on the boot mode)
• Reset the board(System Reset on CCS)
• Execute the GEL script
• Load the binary

Regards,
Vinesh

Hey Vinesh,

thanks a lot. It looks better now, but the blue LED from the profinet-example doesn't blink.

I have:

• Launch Target configuration(XDS100v2) -> check
• Connect to CortexA8 -> check
• Put a "Hardware Breakpoint" at 0x402f_0400 or 0x0800_0000(Depending on the boot mode) -> check
• Reset the board(System Reset on CCS) -> check
• Execute the GEL script -> it only run sucessfully, if the processor stop and the breakpoint is active! but can i use the example without the breakpoint settings?
• Load the binary -> it's only sucessfully, if i had copied the example into workspace, if i build the example in the download folder without workspace copy, there occurs an error!
• When the CortxA8 run and i make a break, there occurs an error to like this:

------------------------------------------------------------------------------------------------------------------------------

CortxA8: Trouble Removing Breakpoint with the Action "Finish Auto Run" at 0x80025fe4: (Error -1066 @ 0x3332) Unable to set/clear requested breakpoint. Verify that the breakpoint address is in valid memory. (Emulation package 5.1.232.0)

-----------------------------------------------------------------------------------------------------------------------------------------------

Do you know why the LED doesn't blink, although there is an Siemens S7 connected via Profinet?

Regards,

Sebastian

Sebastian,

When you reset the board without a breakpoint, the default application residing in the flash will execute automatically. If you require to skip this step, then just make sure that there is no application in the flash memory(SPI/NOR).

You have to stop CortexA8 as soon as you connect the target.

The example paths are relative to an environment variable IA_SDK_HOME. So copying the example alone might cause issues(cross-check the paths, you can configure it accordingly)

For ICEv2, I do not think there is a blue LED, instead a blinking orange LED will indicate the alive status.

As for the LEDs(I suppose you are referring to the Digital outputs), you need to make sure the PLC is configured properly(with the proper GSD), and also you need a jumper connected as mentioned in the user guide

Regards,
Vinesh

Sebastian,

I very rarely do hardware reset of the board. Usual sequence is:

- connect to Cortex-A8
- use CPU Reset(HW) in CCS
- run GEL (should have no errors!)
- load the binary (usually runs to main() using CCS generated breakpoint)
- start and debug the app
