Sam,
Here's the ifconfig output generated from putty running on my WIN-7 workstation
via remote desktop from my WIN-10 ZBook. Ethernet cable from Pi4 to 7i92 is 2'
long.
And with or without LinuxCNC running this is what I get:
pi@linuxcnc:~ $ cd mesaflash
pi@linuxcnc:~/mesaflash $ sudo ./mesaflash --device 7i92 --readhmid
lbp16_access.send_packet: Operation not permitted
Aborted
