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

VOXL CPU Performance with ROS
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:
[ 586.199252] type=1123 audit(1641721335.544:9489): pid=15875 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0-s15:c0.c1023 msg='cwd="/root/.ros" cmd=69776C69737420776C616E30207363616E terminal=? res=failed' [ 586.229739] type=1123 audit(1641721335.574:9490): pid=15876 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0-s15:c0.c1023 msg='cwd="/root/.ros" cmd=69776C69737420776C616E30207363616E terminal=? res=failed' [ 586.269861] type=1123 audit(1641721335.614:9491): pid=15877 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0-s15:c0.c1023 msg='cwd="/root/.ros" cmd=69776C69737420776C616E30207363616E terminal=? res=failed' [ 586.304811] type=1123 audit(1641721335.644:9492): pid=15878 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0-s15:c0.c1023 msg='cwd="/root/.ros" cmd=69776C69737420776C616E30207363616E terminal=? res=failed' [ 586.505185] audit: audit_lost=900 audit_rate_limit=20 audit_backlog_limit=64 [ 586.505199] audit: rate limit exceeded
Any suggestions on how to diagnose this issue?

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

Unbricking fails due to "protocol error"
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 [INFO] Rebooting into fastboot... error: no devices/emulators found [INFO] Waiting for fastboot...

RE: Setting up network interfaces
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? -

@modaltb Using USB 2.
Got my hands on an OTG adapter, seems to be doing the trick. -
VOXL as usb2 host not working via j8
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,

Unbricking
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,
Nirge
