Not sure what the issue is? That error message just says that you need to rebuild and reflash the Klipper firmware on your mcu and toolhead boards.

Yup that’s what it says. 😊👍

@pastel snow I spent all night trying to reflash my Manta “by wire”. I’m supposed to be able to flash/update them through SSH using the UUID
But for some reason the only way I could make any sort of progress was by forcing the board into DFU mode.
Even then, once i flash klipper (after flashing canboot) it stops working. (It won’t even report that it’s out of date) until i reflash canboot and i get the same error (as seen above)

So, Manta is your MCU, right? Are you using it in CAN Bridge mode?

[thorn smelt]

Yes and yes. Oh and I did make sure to do a “make clean” several times. (Admittedly I’m sure I’ve missed some sort of obvious step, it was late and it was starting to drag me down a bit)

[pastel snow]

Are you trying to flash Klipper while the device is still in DFU mode after the canboot flash?

[thorn smelt]

@pastel snow (sorry forgot to reply) Nope I hit the reset button after flashing in DFU mode. And just for double checking, I do a complete shutdown and power up (properly..not just the “power_button.exe”)

[pastel snow]

OK, so what do you see when you run ls /dev/serial/by-id after the canboot flash and reset?

[thorn smelt]

“Is: cannot access ' dev / serial / by-id /': No such file or directory”
But I can see in the machine menu in the GUI that the canbus network is up on can0
And as you can see in the config, the MCU is addressed by UUID not USB

[pastel snow]

OK, can you quickly double-click the reset button on the MCU?

OK, wait. I was reading the wrong instructions.

Run this: python3 ~/katapult/scripts/flashtool.py -i can0 -u yourmainboarduuid -r

[thorn smelt]

Here’s a bit of a rub.. I’m at work for an other 4.5 hours 😁
I’ll do that then.

Will you be around?

[pastel snow]

Not sure.

Just post the results and if there is anyone around, they might look at it. If not, I can try to check back in when I am available.

[thorn smelt]

What kinds of results should this command give? I’m assuming it’s not to flash any firmware. There’s no canboot file specified

[pastel snow]

It will just reboot the MCU into Katapult/CanBoot mode.

[thorn smelt]

Ah ok 👍
