Duet2 Eth Klipper Firmware issues
-
@droftarts totally understand. I figured with the little klipper content on here this was probably going to be the case. The flash speed seems right, as far as all the other content I have seen about flashing klipper on the Duet. Most tutorials show between 47-50 pages, and it taking no more than 2 seconds.
Everything else I just followed the instructions from others online so there is no reason for doing it any way.
I did revert back to ensure the board was functional, and everything still works when back on the original firmware.
If I find a solution I will update this post, just in case someone else stumbles across it. Thanks

@dtmcnamara it might be worth asking @Luke-sLaboratory if he has any ideas about this one.

@droftarts said in Duet2 Eth Klipper Firmware issues:
I'm also not sure about using /dev/serial/by-id/ as the port.
Thats normal under klipper because /dev/ttyACM* is not reliable to be stable across boots (USB enumeration can change with kernel and/or klipper formware updates), and you may have multiple boards (displays, toolboards, multiple control boards for larger numbers of drivers or additional IO). Configuring by id gives you a stable identifier.
-
@dtmcnamara Ah, yes, the binary is much smaller, so would flash faster. That makes sense. I still think using both the port name and the U parameter might cause conflicts. Did you try without the U parameter?
@oliof Thanks for the info! Another Linux-command-line thing I didn't know about. Unfortunately it doesn't seem to have made it into macOS, where devices can't be connected to by id.

@dtmcnamara need to use raspbian BUSTER (version 10)
Raspbian bullseye (version 11) has a bug whan flashing klipper onto duet boards, and does a semibrick of the board.
Lately it´s been said that flashing the LITE version of raspbian, and right after that using KIAUH you could flash it with both versions (buster and bullseye).
I have a SD with buster that flashed successfully duet3 mini5 and duet2 wifi

@apak what does semibrick mean, and do you know how to recover?
-
@oliof when you flash klipper fw it doesn´t finish quite well, and board does not respond.
Just reflash RRF again and it works fine.That´s a semibrick...board not working but you are able to recover it by regular procedure.
-
@apak is that captured in a bug on the klipper side? I worry that the conspiracy theorists talk about Duet3D "locking" the board.
-
@oliof nothing to do with klipper or duet, it´s a debian or bossa bug....
-
@oliof its 100% a debian or bossa bug. Duet has been nothing but awesome in their quest for true open source.
Have you got it working? I've definitely run across that annoying bug
-
@Luke-sLaboratory I havent tried, I just like to be on the up and up (-:
-
@dtmcnamara it took me several minutes to flash 100 pages or so on duet 2 upgrading the firmware,perhaps that is different
