Issues flashing firmware to PanelDue 7i over USB

cdoe

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
Version      : v1.13 RC2 Feb 20 2013 13:25:17
Address      : 4194304
Pages        : 512
Page Size    : 512 bytes
Total Size   : 256KB
Planes       : 1
Lock Regions : 16
Locked       : none
Security     : false
Boot Flash   : false

output when flashing with 3.5.0:

./bossac --port=/dev/ttyACM0 -e -w -v -b ~/Downloads/PanelDueFirmware-3.5.0-rc8-7.0i.bin 
Atmel SMART device 0x289b09e0 found

[                              ] 0% (0/346 pages)
Flash command failed

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
Atmel SMART device 0x289b09e0 found

Write 170916 bytes to flash (334 pages)
[                              ] 0% (0/334 pages)
Flash command failed

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

Does Bossa say the flash is complete and verified successfully?

It sounds more like the touch input digitizer has potentially failed preventing the calibration from completing.

bossac says “flash command failed”

I'd give the GUI version of Bossa a try and make sure you're following the steps here.

Let us know if you're still encountering issues.

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

@cdoe why not just flash the paneldue using RRF? just erase the paneldue and reset then use M997 S4 to flash it.
I do that with paneldues I have even. saves messing with BOSSA

cdoe

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

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