VOXL2 bricked and not entering forced Fastboot
-
@TPSetati I am just realizing that the VOXL2 board was already in QDL mode before I switched SW2 to the ON position. Even if I switch it back to off, it remains in QDL mode. Is there another switch that could be causing this?
-
@TPSetati What does your hardware setup look like? Do you have anything else connected to your VOXL2?
-
Our setup is similar to that on https://docs.modalai.com/voxl2-d0006/. All of this is on a Sentinel drone.
-
@TPSetati Depending on the sentinel kit it may have an add-on board attached to VOXL2 that has a SW2 switch as well.
-
The add-on board we have connected is the WiFi board with its Fastboot button. The only SW2 I have spotted is the one depicted on https://docs.modalai.com/voxl2-qdl/.
Before the system image got corrupted, everything worked fine and no buttons or switches were engaged. I am finding it weird that it seems that the board went into EDL mode upon corruption with no changes made to the hardware.
-
@TPSetati Interesting, do you know what happened that caused it to brick?
-
We flew the drone and had a semi-hard landing (I say semi-hard because we've had harder landings but the drone got back to flying easily). When we went in to check the drone, nothing was physically damaged. We just noticed that the WiFi was off.
We thought cycling the power would work, as it usually did, but this was not the case now. When trying to connect via ADB and noticed it didn't work, that's when we knew something was wrong.
We tried fastbooting the board, and that also was not working. So we realized that this problem is deeper than just a bricked board.
-
@TPSetati Yeah it definitely seems like there is some sort of hardware issue. It's possible something has become disconnected or unseated, I would double check all cable connections, camera connections, board to board connections, etc. A semi-connected or incorrectly connected cable / camera / board can cause inconsistent boot or power issues which may be what you're seeing.
-
We'll have to take a look on our side then. Could we receive the schematics of the board and perhaps the source code for the qualcomm so we can test?
-
@TPSetati I'd recommend sending it in to us for an RMA so that we can do an inspection: https://www.modalai.com/pages/rma
