On czw, at As I wrote before in all our devices we give the user normally only technicians in our production the ability to change MAC address. I just want to know whether or not this can be easily done and whether this will work reliably.

Hi Travis, thanks for the response, I will try to edit the template and see how it works. What I am saying that you can change MAC address on the fly but I think it’s better to do it before you connect the cable and start data transfer. And yes, this not something you are expected to do on a normal operation, so resetting is the best choice.

I have looked into the code and unfortunately, the MAC is set via a define macro and I do not see how I can change it during run-time of the lwkp when I read the unique number.

And yes, this not something you are expected to do on a normal operation, so resetting is the best choice. Maybe I have to bring the netif completely down, remove it, change the configuration MAC address onlyadd it again and bring it up?

As per established data flows, other hosts will send to the old MAC until their respective ARP cache entries expire, and that depends on their respective timeouts.
In reply to this post by Freddie Chopin Hi, as long as you are not using an application protocol that embeds layer-2 info in application data, lwil shouldn’t have any issues with buffered data in lwIP, since it does not hold layer-2 info; it is added by the driver.
I successfully managed to modify the files generated by Dave: Hi, If you start networking with one MAC address and later change it you will probably have some packet lost. Once you had obtained a new MAC address you had to influence this changes on the below mentioned 3 functions which writes to the Kwip address register.

Changing MAC address of network interface? So, how can I change the MAC address from within the main routine or some function call by the main routine without changing the files generated by Dave?

If it cannot be done, then I will write in the documentation that any change of MAC is effective only after hard reset of the device de-initializing and re-initializing network interface is too disruptive. No license, whether express or implied, is granted by Infineon.
How to set a MAC address

If you do not have any network activity, change MAC and start networking you should not have any problems. Lwio about currently active TCP connections?
