Updating 7i77 firmware failing. was created by sliptonic
Full disclosure: This is a machinekit install
I'm updating my mill and trying to get rid of a persistent warning:
"hm2/hm2_5i25.0: Warning: sserial remote device 7i77 channel 0 has old firmware that should be updated"
The mill has three servos and a stepper for the 4th axis. I flash the 5i25 like this:
sudo mesaflash --device 5i25 --write 5i25_7i77_bstech.bit
And everything works correctly but the above warning shows on startup.
I downloaded the latest serial firmware and have tried to update the 7i77 without success. Log follows. Note, I also tried this as root which fails with a different error that it won't run as root. So I guess this is a difference between LCNC and MK. Can someone point me to a MK friendly upgrade procedure?

That isn't necessarily wrong, the setsserial utility always exits with an error. (documented behaviour..)

Have you power cycled the 7i77 after the flash?

Can you try running say the update7i77d.hal script a bit at time a via
halrun to see where it fails? that is, type the commands in the script
one at a time in a halrun session.
Maybe the firmware is not installed or in the wrong place or setsserial has some generic problem with the MK environment

Good call. Nailed it. The machinekit docs say, "The firmware should be placed somewhere in the /lib/firmware/hm2 tree, where the Linux firmware loading macros can find it." But it needs to be exactly in /lib/firmware/hm2/sserial.
Probably should have caught that myself. Thank you.
