Thanks again, updating from duet board worked. Digitizer doesn't work though but that's a separate issue

Thanks I'll try that. Didn't realise it can be done while paneldue has no firmware at all...

I've been able to flash 3.4.1 with bossac. GUI version is windows/macos version only which i don't have, so it seems that my paneldue is now just a bunch of useless hardware

bossac says “flash command failed”

Hi,
I've tried re-flashing 3.5.0 rc 8 firmware over usb and followed process described in documentation.
PanelDue had 3.4.1 firmware previously. However, it was in storage and was stuck in calibration prompt - i.e. a dot on top of the screen was visible and there was a prompt to touch it, but that was not progressing as if touch was not detected.
Here are some outputs from bossac:

$ ./bossac --port=/dev/ttyACM0 -i
Atmel SMART device 0x289b09e0 found
Device       : ATSAM4S4
Chip ID      : 289b09e0

output when flashing with 3.5.0:

./bossac --port=/dev/ttyACM0 -e -w -v -b ~/Downloads/PanelDueFirmware-3.5.0-rc8-7.0i.bin

Similar output when trying with version 3.4.1:

./bossac --port=/dev/ttyACM0 -e -w -v -b ~/Downloads/PanelDueFirmware-3.4.1/PanelDueFirmware-3.4.1-7.0i.bin

Are there any troubleshooting steps I could try to figure out why flashing no longer works and if hardware is in working condition?
There are no torn wires or connector strips on visual inspection

Only got my hands to it now. Sadly 140R resistor burned out so badly that there are no traces left to put replacement component. LEDs are fine though. Has anyone tried using silver tracing pen to re-draw traces? Will it work properly with moving part like effector?

Thank you.

Is there something similar to replacement parts for duet3d but for smart effector?
I'll need to replace LEDs (D1, D9 and D7) as I was switching from 24v to 12v and then back and forgot to remove 12v jumper for LEDs so they were working w/o extra resistor for some time.

When +12V is connected to centre pin of V_FAN voltage selection block - does it bypass mosfets? Also do I need to connect negative from buck converter to negative of duet wifi? Looks like negative from buck converter output is common on both sides so it's common with negative on PSU as well.

Thank you. That was it.
