Very good, thanks for reporting back.

Does that mean that the network interface for the LPC17xx works well?

> What was happend, the configTOTAL\_HEAP\_SIZE is few for the new tasks

In all new network interfaces I am adding logging about essential resources: free heap size, free network buffers, etc. The logging is done from a function `prvMonitorResources()`.

That function is only enabled when logging is enabled (`ipconfigHAS_PRINTF`).

Hi @htibosch

Yes, using the driver of LPC40x8.

I’ll see this.

I don’t know if i can do this here, or create a new topic. But i need change DHCP and static in runtime.

I’m going to mark this question as solved to help anyone else in the future to discover the solution. Please feel free to create a new topic @ulysses. Thank you
