@modaltb Using USB 2.
Got my hands on an OTG adapter, seems to be doing the trick.

@Chad-Sweet Hi, the utility shows the same CPU usage if I add usr & sys.

Hi,
I'm migrating an app to VOXL, and noticed the performance is better, but the hidden "sys" values are negating any advantage (28% when 21% is for system).

Mem: 2737440K used, 1123880K free, 41796K shrd, 140144K buff, 1824000K cached
CPU:  6.9% usr 20.9% sys  0.0% nic 67.4% idle  0.0% io  2.3% irq  2.3% sirq
Load average: 3.84 3.14 1.65 4/750 13545

Using dmesg it seems it's overflowing with errors:

Any suggestions on how to diagnose this issue?

Missed that part, thank you, it seems to do the trick.

Hi,
I have bricked a voxl in dev, trying to restore using the debug expansion, but the process fails:

~/Downloads/modalai-3-1-0$ sudo ./install.sh 
[INFO] adb installed
[INFO] fastboot installed

This process will completely wipe your VOXL
Would you like to preserve the /data/ partition which contains
things like calibration, wifi config, and docker images
To preserve files in /data/ answer Y
To wipe /data/ for a full factory flash answer N

Enter Y or N: 
n

Would appreciate any insights and help I can get.

@tom Originaly configured it station, did not change it when tried to configure it to static.

Hi @tom
I tried this for wlan0 and it doesn't work for me, am I missing a configuration for out-of-the-box VOXL before I can add /etc/network/interfaces? or is it overriden by voxl-wifi?

Hi,
Connecting my laptop to voxl via adb works on j8 connecter.
However, an STM based device is not recognized when connecting a client device to voxl using micro-usb to micro-usb cable.
The same device is recognized when connecting via the usb expander (https://docs.modalai.com/usb-expander-and-debug-datasheet/)

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 0483:5740 STMicroelectronics STM32F407
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

https://docs.modalai.com/voxl-as-usb-host/ does not specify any special requirements.
Am I missing something? is the micro-usb cable needs to be an OTG cable with ID pin?
Best regards,
Nir

Hi,
Just starting up a migration to Voxl as a companion.
Was reading up and wondering how often does it brick if shut-down without shutdown -f?
Is this a common occurence or a 1 in a 1000?
@see https://docs.modalai.com/unbrick-voxl/
Best regards,
