TM4C1294NCPDT: TI RTOS

Part Number: TM4C1294NCPDT

Dear Sir,

We have designed a system using TM4C1294NCPDT TI RTOS.

14No's of devices connected in a network and is working fine for more than 5 months, afterwards we are scaling up the network with 72 devices in the same network.

When we started networking scaling up more than 30 devices entire network getting collapsed and is not getting back until we restart all the devices in the network.

Can you guide us how to fix issue and what all the failure causes.

Awaiting for your reply

Once the network is down after several restarts only device starts pinging

Please look into this also

I suppose it still works at 29 devices or less, correct? I will suggest you first increase the heap and stack sizes and then gradually increase the number of nodes. For example, start at 30 and later 31, 32....until which it doesn't work again. I want to know if your problem is related to lack of heap/stack memory as number of sockets created increases.
