problem with lwIP and timers - Xilinx

WebThe TCP/IP protocol provided by the Lightweight IP (LwIP) is used to exchange strings between the board and a remote client terminal. The board obtains an IP address and publishes its hostname using the DHCP protocol. The System Timer Module (STM) is used to update the internal LwIP timers. WebThe default lwIP implementation is to have these timers enabled all the time, even if no timeout events are active. This increases CPU usage and power consumption when using automatic light sleep mode. esp-lwip default behaviour is to set each timer “on demand” so it is only enabled when an event is pending. Web17 apr. 2024 · On investigating, both pcb->last_timer and tcp_timer_ctr had the same value of 58. pcb->last_timer = tcp_timer_ctr = 58 It will be of great help if anybody can explain the reason for this behaviour of LwIP.
