I'm trying to manually configure my application using C code and Cfg*() functions (as described in spru523k, section 2.1), but when I ran my code, the console showed the message:

ti.sysbios.family.arm.m3.Hwi: line 143: E_alreadyDefined: Hwi already defined: intr# 56

and the function NC_NetStart() returned -1. Can anyone help me to solve this?

I'm attaching a print of the ROV -> Hwi screen and my code:

Hi Ronan,

When you use the .cfg to configure the NDK, it generates the Network Stack Task. Since you are providing it also, you are getting duplicates. I would simply remove the NDK related code from the .cfg. You'll need to add in the the NDK library also (since the .cfg does that for you also).

Hi Todd,

The only code related to NDK in my .cfg file is the following:

/* ================ NDK configuration ================ */
var Global    = xdc.useModule('ti.ndk.config.Global');
Global.pktNumFrameBufs = 10;

I put these lines in order to solve another problem described in this thread:

Do you know how can I set the pktNumFrameBufs value without use the .cfg file?

Thanks in advance,

Ronan

Ronan,

You need to supply the number of frames in source code. I've attached an example. The constant that interests you is PKT_NUM_FRAMEBUF. You'll need to provide all the buffers also.

Hi Todd,

Thank you so much, your example helped me a lot! Now, it seems that the program works when I set the static IP, but when I use the DHCP config (as shown in the example), I got these messages in the console:

Service Status: DHCPC    : Enabled :          : 000
00000.000 TaskGetEnv: FATAL: NDK_hookInit() must be set in DSP/BIOS Task module config (hookId == 0xffffffff)
00000.000 TaskSetEnv: FATAL: NDK_hookInit() must be set in BIOS Task module config (hookId == 0xffffffff)
Service Status: DHCPC    : Enabled : Running : 000
00000.000 TaskGetEnv: FATAL: NDK_hookInit() must be set in DSP/BIOS Task module config (hookId == 0xffffffff)
Service Status: DHCPC    : Enabled : Fault    : 007
00000.000 TaskGetEnv: FATAL: NDK_hookInit() must be set in DSP/BIOS Task module config (hookId == 0xffffffff)
Service Status: DHCPC    : Disabled :          : 000

and then the CfgFree() and NC_SystemClose() are called. Do you know what these messages mean?

Thanks in advance,

Ronan

Hi Ronan,

The Task adaptation module in the OS library requires a hook to be able to save and load private environment pointers for the NDK. This is done by creating a SYS/BIOS hook. A hook module must be created to call the OS hook functions NDK_hookInit() and NDK_hookCreate().

If you use XGCONF to configure the NDK, these objects are all created automatically. Therefore, if you are not using this you have to manually create those objects. One thing you can do is create a new project and look at the way the configuration generates the needed objects and try to replicate it.

Thanks,
Gerardo
