Failed to write firmware. Timeout.

Recommended Posts

Posted · Failed to write firmware. Timeout.

I am trying to update the firmware on my OUM to support a heated bed, however, everytime I try to upload my custom HEX from robotfuzz it times out. I am able to load the default firmware without an issue though...

I have tried Cura 15 and 12, as well as Windows and Linux.

It does seem to erase the firmware (as it will not post if you un-power it before reloading the default).

Ideas?

When I run Cura from Linux I get a warning about the serial port not being valid (I can grab the full message if that helps)...

Is it possible the generated HEX is invalid?

Additional things I have tried:

Re-creating the hex.

Removing all sensors.

Flashing with and without external power.

There is a little problem in that if you pick the wrong sensor type, the firmware enters an error state when it first starts.

Eliminate some variables and get some confidence in the builder by using the most basic template to build the firmware for the simplest configuration and see if you can get that to work.

Either Basic UM or Basic UM plus Ulticontroller and do NOT change for the heated bed.
