ADB Connecting Issue with VOXL2 Board

dlee

@tom One more question. Since we have three VOXL2 boards behaving the same way can we buy one RMA (PCB) diagnostic for all three boards or do we have to purchase a RMA (PCB) diagnostic for each board that is faulty?

Thanks.

tom

@dlee I didn't realize all 3 were exhibiting this behavior, if that's the case something else is going on.

What system image and voxl-suite are you flashing on top of the QDL image? Are you loading or running anything else on top of that??

tom

@dlee Do you have anything plugged in to your VOXL2s? cameras? modems? add-on boards, usb devices etc.?

dlee

@tom I plugged microhard module to use station wifi on voxl (not in microhard). But when I detach the microhard modem, it still didn't work.

tom

@dlee Remove the microhard modem and anything else you have plugged in. Does it then allow you to stay in ADB?

dlee

@tom Removed it. ADB wasn't detected. Do you have some advices my setup?

@dlee I would plug in USB-C and see what dmesg -wH shows

@tom This is the result of dmesg -wH

@dlee said in ADB Connecting Issue with VOXL2 Board:

QUSB_BULK_SN:73AD68FF

When VOXL2 is showing up as QUSB_BULK_* in USB devices it means it's in emergency download (EDL) mode.

It goes into EDL mode:

if the EDL switch (SW2) is "ON"
VOXL2 fails to boot normally do to an error

If the error is recoverable, using QDL resolves SW/flash related issues. If after using QDL to reflash, and turning SW2 back off, the VOXL2 continues to boot into EDL mode, in my experience there's possible HW damage that is causing bootup to fail....

@modaltb If HW was damaged, Can I get RMA service?

Hi @dlee information on the RMA process is here : https://www.modalai.com/pages/rma

Hi @dlee
Can you please double check SW2. From that photo you posted, it seems as if it may stay be in the "ON" position, which would keep it in "EDL" mode and show up as "QUSB_BULK..." instead of an ADB debug device.
Please be sure to follow this step carefully when performing QDL updates:
https://docs.modalai.com/voxl2-qdl/

We do not have many HW failures on Voxl2 in the field from routine use, so to have one so soon is surprising. However, if you are confident you are following all instructions and still wish to RMA it, we'll test it again to check for all basic functionality and debug the root cause of the failure, if any, and prompt you for further actions.
Thanks!
