Is there anyone use ETHARP_TRUST_IP_MAC ?
One interesting happen about it is from my customer. He use the A version with ETHARP_TRUST_IP_MAC enable in LWIP, it works well after power on.
But PING request always time out after running some days, I also find the PING other device in the network is good. so, I hot reset the Device, the PING issue still exist.
Then, I upgrade the A version to B version with ETHARP_TRUST_IP_MAC disable in LWIP and hot reset, PING issue goes out. Everything goes well now .
Next, I upgrade B version to A version again and hot reset, the PING issue happen again . but if cold reset the device with A version, PING issue goes out. But It will come back
After running many days.
Anyone has known this ?
