Re: [lwip-users] STM32H7 stuck in tcp timer

[yasir arafat]

In my case I had running Http and the problem was while closing connection, by mistake i was trying to free an already freed connection in 'http_closed'. So it is better to call tcp_close if the connection is still active otherwise It will go to free the connection again.

Dear all,

I encountered a problem using the STM32 H7 cube port of lwip. I frequently
see the processor stuck in the tcp timer loop (tcp_fasttmr, tcp_slowtmr) as
it iterates over the tcp_pcb-s. One of them points to itself in the next
field, so it stucks in the loop.
This hasn't happened until I had only one active connection, but I can't
rule it out.

Any advices?
What could cause the problem?


Thanks!
