I have a "legacy" system (2017+) running on 5441x and NetBurner 2.8. It polls J2.10 for a trigger and sends a line from a CSV file out the serial port when the trigger is detected. Embedded webserver, ftp server, and SD card code are all straight from examples. This has worked for several ...

> Why are you are using openssl rather than the Netburner SSL implementation? I needed ECDSA for a project, which is not provided by NB, and decided to go all the way and port openssl to NB. That decision enabled the current project to quickly bring in standard des, 3des and MAC libraries. The memor...

That's good info. My application uses opensll as a library, so some dynamic allocation may be in play. But this happens right after boot, before any openssl lib functions are called. Based on what you wrote, I rebooted to the boot loader and then sent the factory test image from the IDE. Back in bus...

Yesterday I was running along developing on my 5441x system, IDE 2.8.7, and I started getting false "Out of Memory" errors on code load. The first time it happened, I was going from a Run build to a Debug session with no source changes. My build uses less than 5% of memory, see screenshot....

Hi Tom, I can see the declared stack sizes, and have changed a bunch of on-stack arrays to static. None were bigger than 64 bytes. I suppose I could declare a new task with a nice big stack for all my UserMain stuff. But this is supposed to be a high reliability system. Now that I think I have seen ...

I suspect I am running low on stack space in a Mod5441x project, and need some help accessing OSDumpTasks and OSDumpTCBStacks. They are not in C:\nburn\lib\MOD5441x.a or DBMOD5441x.a (filesinspected with emacs). The declarations in my ucos.h are grayed out, looks like UCOS_STACKCHECK is not defined....

Followup: it turns out that my customer's code, written for Winsock, is the source of the problem. hostInfo = gethostbyaddr((char *)&addr,4,AF_INET); // NULL at 168! if ( hostInfo==NULL) return(42); hostinfo is always NULL - UNLESS the whole system is set up for 192.192.192.xxx! Then it works. S...

Does anyone reading this know about IP range dependencies on TCP socket behavior? It seems like the kind of thing that shouldn't happen. I'm working with MOD54417 (dual ethernet). NB IDE is 2.8.2. My customer wants to connect as a TCP client to eth1, on port 10033. They use two address ranges, 192.1...

Also, you will need the 2.8.7 release for that entire list. I guess so, since none of the Cipher names appear anywhere in my 2.8.2: Larry@GLPC_02Dec2013 /cygdrive/c/nburn $ /bin/find | xargs grep TLS_ 2>/dev/null ./examples/StandardStack/BoardLock/checklock/main.cpp:#ifdef SSL_TLS_SUPPORT ./example...

That might work. How do I use these ciphers? I don't see them in any manuals or header files.
