M540 and MAC address problems on Duet 3

T3P3Tony

@sergio if 3.2 resolves the issue that would be helpful to know.

dc42

@sergio what I need is the M122 reports from both duets that are being given the same MAC address.

@dc42
Sorry, I was asking someone to turn off that machine in that factory. I cannot access both remotely through the VPN so I needed remote hands to help me.

None of my Duet3 change MAC address.
Here is another example:

3.2 doesn't resolve the issue.

dc42

@sergio I confirm that there are two bugs:

M540 does not set the MAC address in the Ethernet driver;
When constructing a default MAC address, the last byte of the processor unique ID is not used. This means that multiple Duet 3 boards from the same manufacturing batch may have the same default MAC address.

#2 is quick to fix so the fix will be in 3.4.0beta5, which we hope to release later today. #1 may take a little longer.

sergio

@dc42 Thanks a lot.

sergio

@dc42
If you are looking into that code. The hex format also doesn't seem to work anymore, not sure if you are removing backwards compatibility, but if that is the case a note would be good on the M540 description.

M540 P0xB1:0xEF:0xD0:0xAD:0xDD:0xFD ; This format doesn't work anymore
M540 PB1:EF:D0:AD:DD:FD

Thanks a lot for the fast response.
Sergio

@sergio yes that hex format has been removed. The M540 example doesn't use it, see https://duet3d.dozuki.com/Wiki/M540.

@sergio the default MAC address clash problem should be fixed in 3.4b5:

@t3p3tony Just updated the firmware and I can confirm that the MAC is correct. Thanks
