Hi,
Please forgive me if this is a stupid question.
I am writing a DHCP server and using udp_recv functionality to handle
incoming broadcast messages on a udp pcb.
I have enabled the BROADCAST flag on the PCB and I can receive the incoming
packets just fine. The udp pcb is bound to ip_addr_any.
Hi Ran,
What about using memcpy, since it can handle unaligned access?
#define ip_addr_copy(dest, src) memcpy(&((dest).addr), &((src).addr),
sizeof((dest).addr))
Maybe that would work? I am not 100% sure though.

I concede I might be too paranoid, but I'd rather look stupid asking the
question than not :)

I have been looking at how SNTP works, as I want to allow the user to
change the SNTP_UPDATE_DELAY somewhat dynamically (I understand I will need
to enforce minimum 15 seconds between requests).
It got me thinking about how sys_timeout works. This function manipulates a
linked list in timers.c. I
Thank you Simon, and everyone else who contributed to the discussion.
I have had both tasks set at the same priority (RTOS task priority, nothing
to do with the Cortex interrupt priority). I have not noticed any issues
with this so I will leave it as is for now.
I don't think that the comment is a
I was looking through my codebase recently (a mix of code from LPC Open,
and also a project I inherited) and I saw a comment which I want to fact
check:
/* TCPIP thread must run at higher priority than MAC threads! */
My software is using FreeRTOS. The Ethernet interrupt only signals a
semaphore
