Re: [lwip-users] lwip on pico_w

[Christoph M. Wintersteiger]

Hi Edward,

 

Yes, I’m using lwIP on Picos as well. In my case, the MQTT client was a bit of a pain and kept throwing me into random panics too. The problem is that it doesn’t take the state lock. Basically, all calls to mqtt_* functions have to be guarded by cyw43_arch_lwip_begin() / cyw43_arch_lwip_end(). Once I did that, everything became quite stable for me.

 

Cheers,

Christoph

Hello All:

I have a pico_w running mqtt iperf tcp sever and ntp. I runs ok for several hours then I get ****panic*** which appears to be coming from pico-sdk runtime.c?

Is any using lwip with pico_w?

Thanks in advance.
