NDK can be restarted only once on DM648

Victor Ivanov
Expert 1160 points

Hi All!

For some reason (see this thread http://e2e.ti.com/support/embedded/bios/f/355/p/223029/835523.aspx#835523) I decided to restart NDK stack and I found out that NDK stack successfully restarts only once.

My configuration:

CCS 5.1.1.00031
bios_5_42_00_07
ndk_2_20_06_35 
ethss_dm648 from ndk_2_0_0. According to TI's advice all "printf" were removed
The project was taken from
ndk_2_0_0\packages\ti\ndk\example\network\helloWorld
This project originally was for CCS 3.3 so I had to convert it to use with CCS 5.1. 
I did the following changes in the pfoject:
- an IP address is set statically
- dtask_udp_hello demon and its creation were commented out
- A MainTask thread was created
int MainTask(Arg arg0)
{

while(1)
{
TSK_sleep(30000);
printf("NDKRestart\n");
NC_NetStop(1);
}

}

So, the system does nothing except  restarting NDK stack every 30 seconds.

To test if NDK is OK I ping the board from a PC.

After the first restart the board continues responding to ping but after the second restart it stops responding. Other restarts don't improve situation an even make it worse. See the log from CCS console:

It seems that there is a problem with  NDK restarting on DM648.

    I have enable all printf in my previous experiment and I got  the following error message after the second restart:

    Victor,

    I noticed that this thread never received a reply.  Any update on this issue?

    Victor,

    Does this happen because when NDK restarts, the whole procedure is not done properly? Ideally, I would expect EmacStop to be called up by NDK when a restart/shutdown happens. But I noticed this doesn't happen - http://e2e.ti.com/support/embedded/bios/f/355/t/245724.aspx

    Hi Vinesh!

    I haven't had time to investigate this issue. In our project we don't need to restart NDK. I tried to restart it as a temporary workaround for my problem with NDK. But due to the fact that I still don't have a clear understanding when to restart, the restart itself is useless for me.

    InitTx Channel : Unable to allocate 192 BDs for channel 0.512 BDs already in use

    Based on the printout above, I think that the driver merely doesn't free all buffers while shutting down and as the result it runs out of space after second restart. But I haven't investigated why the buffers were not freed.
