Hi all. I'm working on an embedded system using lwip. This system has to work forever without blocks. I'm using lwip on multitask enviroment (FreeRTOS)
I implemented a HW watchdog on my board which can reset the board if microcontroller doesn't kick it in few second. I implemented in my code a simple watch dog manager, which does kick only if ALL tasks set periodically a flag. LWIP has its task (tcpip thread - i'm using socket), and i saw that this task can block forever trought functions in sys_arch.c sys_arch_sem_wait and sys_arch_mbox_fetch. I implemented these functions putting a macro functions inside a infinite loop (execute if timeout parameter is 0). I decided that the implementation for this macro function, caoul be: - get current task handle (using rtos api function) - set its flag in watchdog manager searching its handle in a table Do you think could it be a good solution??? Thanks, Piero
