Sorry a bit OT
John you have Linuxcnc working on a BBB using a Mesa ethernet card ?
If so would you mind if I started a new topic to pick your brain.
To the OP please accept my apologies for going so far off topic.
Cheers
Rob

I don't think this is his problem, since his rpi Linuxcnc talks to the 7i92
just fine. Only mesaflash is having trouble.
Have you tried explicitly specifying --addr 192 168.1.121?
-- Ralph
There is no electrical difference. Just one DB connector and one header for
the non H variety. It turns out setting the address as --addr 192.168.1.121
or if the W5 and W6 are changed to reflect EEROM IP address of default
10.10.10.10 then all commands must have --addr 10.10.10.10.
Reading the manual again it appears that --addr is only needed if the default
192.168.1.121 is not in use on the 7i92. That's incorrect with a Pi4. It's
correct with a PC and a Beaglebone.
Looking at the code, thats pretty strange. The address default is just
"192.168.1.121" Have you tried without the "sudo"? That's not needed
for Ethernet connected cards
Makes no difference if the sudo is there or not.
First just to show that from a physical perspective the 7i92 is there on
192.168.1.121
pi@linuxcnc:~/mesaflash $ ping 192.168.1.121
PING 192.168.1.121 (192.168.1.121) 56(84) bytes of data.
64 bytes from 192.168.1.121: icmp_seq=1 ttl=64 time=0.120 ms
But the mesaflash software doesn't know it's supposed to use the default ip.
pi@linuxcnc:~/mesaflash $ ./mesaflash --device 7i92 --readhmid
lbp16_access.send_packet: Resource temporarily unavailable
Aborted
pi@linuxcnc:~/mesaflash $ ./mesaflash --device 7i92 --addr 192.168.1.121
--readhmid
Configuration Name: HOSTMOT2
General configuration information:
BoardName : MESA7I92
FPGA Size: 9 KGates
FPGA Pins: 144
BTW. The upside is that now we have something reproducible. It may well be
something outside of mesaflash but the issue doesn't show up with older
versions of the OS and what really amazed me is it worked on the Beagle. Has
me wondering if booted a machinekit onto the beagle would it work? Probably
not. The hm2_eth is probably not compatible with machinekit but just curious.
