mesaflash - default interface

Try
mesaflash --help

This is the second time lately that users are trying to change the default EEPROM IP address on Mesa boards, i wonder where are thy getting that info??? I am sure it is in the manual, but in the manual it is also written much much earlier to use the jumper to set it to 10.10.10.10.
So if anyone bumps into that info, please let us know so we can remove it.
And just for clarity,for beginners, NEVER use mesaflash to change the IP address, use the jumpers.

Right, normally there is no reason to change the defaults.
In fact, for almost any setup, you should use the 10.10.10.10 address.

Only real reason I can think of changing the IP address is if you are using multiple cards
(so say 10.10.10.10, 10.10.10.11, 10,10.10.12 etc would make sense)

Exactly, thank you.
I would understand if someone was trying to set 172.n.n.n as those are also in a non routable range.

Nice post

Hello,

so the help-command was the first thing - but it not helped.

So the next Question ist - have i a misunderstanding? I use a PC in my network with LinuxCNC on the IP 192.168.8.160/24 - so for communicating with the mesa-card i have to use the same ip-range - so i have to set the ip to something 192.168.8.xxx/24...
If not - how the Mesacard communicate with Linuxcnc? It is not a solution to use a Class A Network inside my own Network and make some Bridging... I use several Diskstations and CAD-Computer to store my Milling-Files to have it one every machine in my workshop - so for retrofit the old Milling-Machine i will do the same and have it in the same network to have access to my Backup-Servers File-Servers and CAD-PC and so on...

It looks like here are more and more missing informations - i have read so much on the WIki - but not this.
Someone can explain the misunderstading?

It is on the MESA 7i97 Manual on Page 4:

Note: The as shipped default EEPROM IP address is 10.10.10.10. This can be changed
via the mesaflash utility

In the manual from the MESA-Card thre is no informations how to setup the card with LinuxCNC or other Software or make some communications - only wire-connection and jumper-configuration are on the pdf. If someone have a manual that explain how it work with LinuxCNC then this will be fine.. i search again the Wiki...

So have found out the problem of the syntax --help says
--set n.n.n.n

but this is wrong!
Correct is:

--set ip=n.n.n.n

I will fix the Mesaflash help printout.

However, note that in general you should not change the IP address
and use 10.10.10.10 for the card. You do not want the FPGA card to
share an address range with other communications (which seems to be what
you are doing). Because of LinuxCNC's real time requirement, The FPGA card
requires a dedicated connection that is not shared/routed. This is why
the 10.10.10.10 IP address is used.
