Thanks, I spent the morning modifying the 2.8.5 kernel with the changes we've made to it, and it appears to be working without the strange buffer errors.

Cheers

TCP Buffers issue on MOD 5272 with NNDK 2.8.1

Hi All, I've been struggling with some networking issues for a few days now; I've never seen this problem before, but I suspect that all of our devices suffer from it, but the problem only manifests when they are under heavy load. To give some background; the devices produce relatively small data st...

Re: Multicast example

To start with, make sure you have ethernet link....

#include <ethernet.h>

BOOL EtherLink( void );

Thanks Paul,

This is working nicely for me.

Re: Multicast example

Its not a user input, but time delay... To get multicast input the system registers with the local router to receive stuff from the multicast group. If you don't wait till DHCP has finished and you have a link etc... then this might not happen. Try just adding a 5 second wait before registering the...

Re: Multicast example

Hi Keith, You didn't post all your code, but are you returning from UserMain(). To cover all the bases, why do you think a tools revision would make a difference? Looks like a coding issue from what was presented. rnixon, you are correct, the modified multitest.cpp code is below. If some sort of in...

Multicast example

I'm trying to build a very rudimentary SSDP task on the Netburner. I've found the very simple example provided in examples (\nburn\examples\multicast\multitest.cpp), and I'm trying to modify it. The changes I've made are as follows: void UserMain( void *pd ) { int portnum = 1900; char buffer[80] = &...

Re: snprintf Release 2.0 rc 4

Are you discussing strings being interspersed by concurrent tasks? The string operations are interspersed by concurrent tasks, however, the two tasks both use buffers that are allocated on the stack, and these two particular tasks never communicate. The strings are only generated when they're neede...

snprintf Release 2.0 rc 4

I've just noticed that there seems to be a threading problem with printf and floating point values. (And I apologize of this has been covered before) We have a network task and an LCD task, both of which utilize snprintf for generating the ASCII representation of floating point numbers, sometimes th...

Netburner Timer2

I've recently taken over a project from a developer who is no longer with the company, to discover that he was using the RS232 port to debug a MOD5272 implementation. I tried to compile it so I could user the ethernet debugger, however our software uses the Timer2 interrupt. I'm currently using rel2...
