Re: [lwip-users] how to handle multiple TCP socket simultaneously

mbox.err is used in the OS-interface layer only. My implementation (FreeRTOS) increments it if sending a message fails or if the mailbox is not empty when deleted. Jan On 08.08.2017 10:58, Mohsin Madki wrote: > SYS > sem.used: 6 > sem.max: 11 > sem.err: 0 > mutex.used: 0 >

SYS sem.used: 6 sem.max: 11 sem.err: 0 mutex.used: 0 mutex.max: 0 mutex.err: 0 mbox.used: 6 mbox.max: 11 mbox.err: 1 what is mbox.err? On Tue, Aug 8, 2017 at 2:14 PM, Mohsin Madki wrote: > here is the data got from lwip_stats when ethernet stopped working. >

here is the data got from lwip_stats when ethernet stopped working. LINK xmit: 0 recv: 0 fw: 0 drop: 0 chkerr: 0 lenerr: 0 memerr: 0 rterr: 0 proterr: 0 opterr: 0 err: 0 cachehit: 0 ETHARP xmit: 10 recv: 5291 fw: 0 drop: 5 chkerr: 0 lenerr: 0 memerr: 0 rterr: 0 proterr: 5 opterr: 0 err: 0

Re: [lwip-users] how to handle multiple TCP socket simultaneously

Thanks Simon, I mean rest of the processes are working but only ethernet related functions stops working. It's my first project with LwIP so dont know from where to start debug. Now as you suggested I'll try to get data from lwip_stats first. Thanks again. On Tue, Aug 8, 2017 at 10:02 AM, Simon
