Same issue.

Using Pixhawk 6X Pro + Here4 (Model HX4-06248) and the Here4 is detected but does not identified (just shows up as a “?”) in the UAVCAN screen of Mission Planner and the white LEDs never turn off.

I have a second Here4, same model, that is working just fine when I switch them out … so it does not appear to be anything to do with the Pixhawk or Mission Planner settings.

Is there a way to “factory reset” or Flash firmware without Mission Planner?

Does it show as maintenance? Or operational?

Shows as operational but no info.

If I go to the inspector and expand the CAN bus messages, here is what I get:

Okay, ID 10 is not here4. That’s flight controller. Looks like no here4 in this. Have you checked power? CAN enabled?

8

The Here4 is connected and the CAN bus is active and working. I did not try and update the here4 firmware to use the FC functions. (I updated the Pixhawk 6X Pro firmware, but not the Here4)

Is there a way to flash the firmware or factory reset the Here4 without using mission planner?

10

This looks like bootloader itself is not functional. You need to pick bootloader and flash it via SWD. And then firmware via DroneCAN tab.

11

A) I have no idea how to do that, is there a walkthrough somewhere? Also, what is “SWD”?

B) When I use the other Here4, everything looks fine, as seen below. The only difference is unplugging the non-functioning Here4 and plugging the other one into the same CAN port on the Pixhawk 6X. Dunno if that helps at all.

If your saying that I need to update the device using the method shown in the manual … I can’t do that, because Mission Planner doesn’t recognize the device in order to update it.

13

Yes. That’s the reason why you’ll have upload bootloader via SWD. @philip can maybe share better option.

14

You can find bootloader here.

Find here4-bl.bin

15

Is there a tutorial anywhere for using the SWD and flashing the bootloader?

16

@philip please guide to update boot loader via swd. I have lots of here4 stuck in white light

17

Try to run the second one for an hour or two and even that will give you white light eventually or else will give u gps but no compass

There is SWD connector available. It follows same SWD pinouts as Cube. Connect SWDIO, SWDCLK on that to st-link and flash bootloader from the link I have given using stcube programmer.
You can find lot of youtube videos on how to use SWD.
