Hi all,
Running our device (luminary LM3S6965, ARM Cortex-M3) in normal operation mode (with domestic like ethernet network traffic) everthing works fine and it acts very stable (tested for more than 4 weeks). However, using the device in an environment with heavy ehthernet traffic (company situation network) generates very regular a ERR_MEM_CORRUPT error at the Net_Config.c->sys_error() function. At this point the watchdog will reset the device (what else ...).
To test this in-stability behaviour I started stress testing it using flood pings, using 2 terminals (Linux). At this point our device is constantly generating above error and resets. I disabled all own traffic, so only traffic on the network triggers TCP handling on our device (like the ping does).
Someone got a clue?
Thanx!
note: Using RL-ARM v3.14a, MDK 3.10a. (Yep, not the latest.. but before changing libraries etc I'd like to know if the problem sounds familiar to someone)
