Hello!
The code generated for lwIP and Ethernet (Internal MAC) has three threads for working of lwIP and the Ethernet driver.
- tcip_thread: main thread used to execute the lwIP stack all TCP/IP processing is done by this.
- EthIf: Process the RX interrupt on Ethernet peripheral, when new data packet is received passes it to lwip.
- EthLink: constanly monitors the Phy chip for any connection/disconnection and auto-negotiation events.
I am using v 1.17.0 of the IDE (latest at the time of writting)
The problem is that the default value of STACK size of EthIf (Rx Handler Thread) is very small: Only 350 bytes. which leads to stackoverflow. I have manually changed the value from code. But I cannot find any GUI to change this! Only we are allowed to configure the tcip_thread but their is NO option for last two threads.
Further there is only a single constant that is used for initialization of both the threads (EthIf and EthLink)
#define INTERFACE_THREAD_STACK_SIZE ( 1024 )and this same constant is overwritten that causes confusion.
