Is that master core need to be 1? 

I was working on ARM core of 66AKE05 , and i think its a slave core. The exit is occurring at 

rc = NC_NetStart( hCfg, NetworkOpen, NetworkClose, NetworkIPAddr );

line. Its a dataabort exception too.

Hope it helps.

Hi Titus,

Will you say the time window needed for the correction on that project? I was just waiting for your input to start my design. I think if you can send patch it will be faster than a proper package release.

Hi,

I was able to rebuild the NDK with this change, and the issue i reported was resolved.

Presently can you provide support on this project? Because i find issue in DHCP client service and it is not able to fetch IP. But for static IP it was able to attach the network set on the example.

We are using K2EVM from TI and i was not able to find the code line in which MAC is configured.

Regards,

Shino

Hi Titusrathinaraj Stalin,

This was an old thread, but presently I would like to restart my work on this. I would like to use NDK with 66AKL06 A15 core for a base station  project.  

The error reported with stack overflow was rectified by rebuilding the NDK, but, while running the project we were not able to get ping to the stack. However the project is running without any errors.

This same application logic works perfectly for DSP core in static and DHCP client mode.

Debug Output:

[arm_A15_0] QMSS successfully initialized
CPPI successfully initialized
PA successfully initialized

TCP/IP Stack 'Hello World!' Application

StackTest: using dhcp
Service Status: DHCPC : Enabled : : 000
Service Status: DHCPC : Enabled : Running : 000

Any clue on this?

Regards,
