Query failed ! I can't connect nor update the firmware of an (old) H7

OpenMV Boards
1

I bough an openMV H7 long ago (the backplate says: OpenMV-H7 R1 10/27/18, and the QR code is marked 04995).

It seems to be working properly:

  • it blink green at boot
  • it blinked blue (the default main.py if I understand)
  • it appears as a usb key of 131kb
  • when I manually edit the main.py in the tiny disk, unplug / replug the USB, it uses the modified version :partying_face:

However, I canā€™t use the IDE. I installed the 4.5.0 on manjaro.
When I try to connect, I get:

  • a first Query failed! popup window, the details shows : /opt/openmv-ide/share/qtcreator/picotool/linux64/picotool
  • then another Query failed popup window, the details shows : /opt/openmv-ide/share/qtcreator/dfu-util/linux64/dfu-util

then the IDE offers me to upgrade the firmware, which a agree, I get one last time the two previous errors, and the IDE crashesā€¦

Iā€™m looking for clues to better understand which part of the communication failsā€¦ I hope itā€™s not the cable! I checked it, changed it, ā€¦ same result

I donā€™t know, Iā€™ve never tested on manjaro.

a first Query failed! popup window, the details shows : /opt/openmv-ide/share/qtcreator/picotool/linux64/picotool

Is there any output when you click show details? If not, it means linux64-bit binaries arenā€™t able to runā€¦

/opt/openmv-ide/share/qtcreator/dfu-util/linux64/dfu-util

Same, you may wish to ldd these binaries and see what they are missing and install those libraries.

The IDE will be unstable if itā€™s tools donā€™t work.

ā€¦

The camera itself is fine.

Thanks !
My wording wasnā€™t perfect but what I meant was that: the two paths to the tools were the sole content of the ā€œshow detailā€ window

Nonetheless, the clue was spot on !

I checked the dependencies, they seemed okā€¦ but many tools didnā€™t had the +x flag which makes them executables.
After correcting this, I can connect to the camera, get the preview, and flash new code (the firmware update still crashes the editor, I may have missed one :smiley: does command line tools exits to update the firmware ? the IDE says my current version is 3.4.1)

I made a feedback to the manjaro packaging team

They would have been tarā€™ed with +x. So, itā€™s odd that untaring would not have that.

Thatā€™s an extremely old IDE. Where did you get it? The latest release is 4.5.0.

By bad (my english is rusty :sweat_smile:). 3.4.1 is the firmware revision as stated by the IDE after connecting the camera, the IDE revision is indeed 4.5.0

Note sure then, 3.4.1 isnā€™t that old. But, you probably need to build the IDE yourself to see what is failing: GitHub - openmv/openmv-ide: QtCreator based OpenMV IDE

If you find a bug a PR would be appreciated. I generally try to handle errors of all types in the IDE, so, something must be failing that isnā€™t expected to fail which is causing the crash. I can confirm the IDE works correctly on ubuntu without any of these crashes.

Iā€™ll try to have a shot at debugging thisā€¦ I canā€™t promise it for this month though :sweat_smile:
Thank you for the solid support !
