Not able to flash using debug board
@Gaurav-Borade , we have one in the works that should be ready shortly, I'll send a link once we get it posted!
Any update on this? I've tried the same process as @Gaurav-Borade, including the instructions here:
and I also see nothing listed under
sudo fastboot devices.
Using the usb-expander-and-debug-user-guide I'm able to start a screen to
/dev/ttyUSB0, but I can't get
adb shellto work after the screen is started.
I'm on Ubuntu Linux 18.04, I'll switch to another Ubuntu 18.04 machine and re-run the debricking procedure to see if anything changes.

If it was working before, and you can confidently get other boards into fastboot, it is likely the PCB has been damaged.

I am having the exact same problem but, running Ubuntu 18.04. My usb expansion board has EMERG boot.
Hi Team, if anyone have the video link, please share so we can try to unbrick it.
@Gaurav-Borade not sure why it didn't make it to youtube yet, but here's a link for now: https://drive.google.com/file/d/1lPK5ypVNkRDaCLJSWZa_J7Cx84tZ2Q_G/view?usp=sharing
@modaltb Thank you for this
Hi, @modaltb I tried with it, but still have not succeeded
Two things I want to confirm
Am I using the right system image? I am using VOXL Platform Release 3-3-0 0.4.6 b downloaded from https://developer.modalai.com/asset
The cable, in the video I can see the cable like below
But I am using the cable,
Is this cable will work? or do I need the same cable shown in the video? please let me know if am doing something wrong here.
Hi @Gaurav-Borade ,
You are correct, the USB cable you have is fine and the image is also OK.
Question: are you using an Ubuntu VM on another host machine? This is something I'm not positive about, should be OK but just not something we've tested too much.
@modaltb Thank you for the confirmation on the USB cable.
Yes, I am using Ubuntu Virtual Box. The board was communicating fine with the Virtual Box previously (Before bricked) so unbricking on that only. I will try it on another machine as well.
