Other Parts Discussed in Thread: SYSBIOS

I want to run the example project on TCIEVM6638K2K DSP core.
I am not able to get the IP address print that should come when we add an ethernet cable to the port.

NetworkIPAddr() // This function is called whenever an IP address binding is added or removed from the system.

Under NetworkIPAddr(),
there is a print -> Network Added
following that, the local IP address used to be printed when I ran the same project on DSP of K2L board.

I am not able to figure out why this is not working the same way for K2K. I need to use this project for socket communication.
Can anyone tell me what I might be missing for K2K board.

Thanks,
Kushal

Hi Kushal,

What is the SDK version used for both K2L and K2K? Thank you.

Hello Rajasekaran,
for K2K I am using 4_0_12
for K2L I am using 4_0_1

Thanks,

Dear Kushal,

Can you please install the K2H pdk package and try it out K2H based NIMU example on K2K board ?

Also please refer to this wiki page.

Hello Titus,

The example that I used was from pdk_k2hk_4_0_12. I thought it is common PDK for K2H and K2K devices.
Is it not the case?
If not, do I need to install PDK for K2H and try the example project given in that package?

Thanks,
Kushal

You used correct PDK only, I thought that you are using K2L PDK since you mentioned K2L as topic name.
Please make sure that you set bootmode as Emulation or DSP no boot mode.
Also do make sure that you modify the code to run as ""Static" IP mode.(refer wiki)

Hello Titus,

Yes I have checked the above mentioned conditions. Static IP as well the board is in DSP no boot mode.
I tried to set a breakpoint inside the NetworkIPAddr().
I could not hit that breakpoint.

I guess server daemon will only be created after I get the binding done ie I get the Local IP address prints on console that are inside the NetworkIPAddr().
This used to work fine on K2L board.
One more thing is that in K2HK pdk also, I have the example named NIMU_emacExample_EVMK2LC66BiosExampleProject only and not something related to K2K or K2H. Is this ok?

Do you have any suggestions for this?

Thanks,
Kushal

Hi Kushal,

I don't have K2K board to test, I tried it on K2H and it worked well.

One more thing is that in K2HK pdk also, I have the example named NIMU_emacExample_EVMK2LC66BiosExampleProject only and not something related to K2K or K2H. Is this ok?

Are you loading and running "NIMU_emacExample_EVMK2LC66BiosExampleProject" example code on K2K board ?
It should be "NIMU_emacExample_EVMK2KC66BiosExampleProject" for K2K/K2H board.

I used to create examples using the below commands.

pdkProjectCreate.bat K2H all little all arm
pdkProjectCreate.bat K2H all little all dsp

You try to create K2K examples like below
pdkProjectCreate.bat K2K all little all arm
pdkProjectCreate.bat K2K all little all dsp

For NIMU examples:
pdkProjectCreate.bat K2K all little nimu arm
pdkProjectCreate.bat K2K all little nimu dsp

Refer to this wiki page.

I tried the example project for ARM after running for DSP.
Generated the example for ARM the same way as suggested.
When I run on ARM core,
After getting the IP address print, I get an error message saying Stack overflow

ti.sysbios.knl.Task: line 373: E_stackOverflow: Task 0x800ef030 stack overflow.
xdc.runtime.Error.raise: terminating execution

I checked the program stack and task stack size in .cfg file and tried to use various combinations.
Still I am getting the same error.
Any suggestions?

Thanks,
Kushal

Yes, its known issue in ARM based NIMU example.
Let you know once the issue is get fixed.

Hello Titus,
Thanks for the early reply. I will go ahead with DSP example then.
