Yes, they will be lost, that's the intention. You have to design the mbox sizes in a way that thins is OK for your application.I'd rather not change the lwip stack code. But perhaps it is possible
to replace all calls to sys_mbox_trypost with sys_mbox_post instead?
Why would you need that?
To avoid to lose any messages!But if it needs to work from ISR it's ofcourse not an option to do that. Sys_mbox_trypost is meant to work from ISR, too, so converting it is no a good idea.
Is there a way to know how many mbox:es that will be created in
the system?
I think one for the tcpip_thread and one for every netconn or socket (used for RX packets for normal connections or accepted connections for TCP listeners).Simon
