Mesaflash 3.4.9 shows "Unsupported ethernet device 7I76EU" despite successful pi was created by AdelRTP
Using 
mesaflash 3.4.9
 with a Mesa 7i76EU (IP 
192.168.1.121
). Ping works, but:mesaflash --device 7i76eu --addr 192.168.1.121 --readhmid
Unsupported ethernet device 7I76EU at 192.168.1.121
No 7I96S board found
Also tried with IP 
10.10.10.10
 after moving jumper W14 up
mesaflash --device 7i76eu --addr 10.10.10.10 --readhmid
Unsupported ethernet device 7I76EU at 10.10.10.10
No 7I96S board found
Is the 7i76EU supported? How to fix "Unsupported device"?

thanks a lot Tommy,
i’m trying to control two servo drives (Modbus RTU) with a Mesa 7i76EU in LinuxCNC, but I can’t use Classic Ladder or PktUART

Have you spotted the new Modbus / PktUART driver? It's more flexible that mesa_modbus. (but only exists in the dev version of LinuxCNC)

You would load the 7I76eu firmware that includes PKTUart support

7i76eu_7i76x1_pktv3d.bin

This file is in the 7i76eu.zip archive downloaded from Mesa's store (in the specifications tab)

You program it with mesaflash, something like:

mesaflash --device 7i76eu --addr 10.10.10.10 --write 7i76eu_7i76x1_pktv3d.bin --reload
