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. In reply to this post by Freddie Chopin. I successfully managed to modify the files generated by Dave: That’s the thing I’m asking about. 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? 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. IPv6 might also need some restart of the node discovery process as neighbours would have old and wrong information.

Infineon distances itself expressly from the contents of the linked pages, over the structure of which Infineon has no control. Changing MAC will most lqip be done extremely rarely, that’s why I don’t want to write a lot of code to actually perform such change.

Can I just change the contents of netif. Thursday, April 07, I was wondering what is the proper way to change MAC address of network interface.

Hi, No reason you could not. Hi, Just a small addition. If I am missing something, please let me know. Msc forum by Nabble.

The views expressed here are my personal opinions, have not liwp reviewed or authorized by ,wip and do not necessarily represent the views of Infineon. 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’ve seen upto 4 minutes as normal. This is done only once during software loading etc 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 code when I read the unique number. Once you had obtained a new MAC address you had to influence this changes on the below mentioned 3 functions which writes to lwlp MAC address register.
In reply maac this post by Freddie Chopin Hi, as long as you are not using an application protocol that embeds layer-2 info in application data, you shouldn’t have any issues with lwi; data in lwIP, since it does not hold layer-2 info; it is added by the driver. Hi Travis, thanks for the response, I will try to edit the template and see how it works. Thanks for any help! Search everywhere only in this topic.

Infineon reserves the right to make corrections, deletions, modifications, enhancements, improvements and other changes to the content and materials, its products, programs and services at any time or to move or discontinue any content, products, programs, or services without notice.
If it can be done, I would prefer to give the user such possibility. But as soon as I do some changes with Dave CE and need to re-generate the source code, the changes are lost.

Hi, If you start networking with one MAC address and later change it you will probably have some packet lost. On czw, at
