@Hunter-Scott When you swapped in the power module board did you update the px4 configuration file in /etc/modalai/voxl-px4.conf? In that file, how is POWER_MODULE set? For the power module it should be POWER_MANAGER=VOXLPM. For standard Starling 2 Max configuration it should be NONE. Can you stop voxl-px4 running as a service systemctl stop voxl-px4, wait a few seconds, then run voxl-px4 from the command line in non-daemon mode with voxl-px4 -d and let the startup script run through. At the command prompt type ver all and qshell voxl_esc status and then include all of the output here? In the log that you sent that did have battery_status, where did that come from? A different drone?

Hi @Aaky
You just went one page in too far

Hope this helps!

@Ashish-Kumar
With ONLY USB-C, the board will not boot, so that is normal behavior.
VBAT is always required.
D1 (Green LED) says the VBAT is present and our local 3.3V is ON.
With just that LED on, it tells me your board is likely stuck in QDL mode and needs reflashing, so the steps Tom provided will help confirm that.

@Ashish-Kumar What OS are you running on your host machine? If linux can you provide the output of lsusb with the board powered and plugged in?

@jmltt SDK testing for Sentinel ended at SDK 1.4.0

That doesn't mean that newer releases won't work, it just means we don't put it through the SW QA testing cycles that we do with our newer platforms.

You likely won't see any major performance improvements on Sentinel with newer SDK releases but there may be some nice quality of life additions such as helper scripts, voxl-portal updates and others.

If you have any questions about any specific packages feel free to ask.

@Ashish-Kumar Can you post a picture of your hardware setup so I can verify all looks normal?

@latif You can order replacement propellors here: https://www.modalai.com/products/starling-propellers-set-of-4?_pos=1&_sid=4b5f94f4e&_ss=r

If you have access to a 3d printer there are some STL files available from our downloads page here: https://developer.modalai.com/

When you plug your VOXL2 in to your machine does it enumerate at all?

Worst case you can submit an RMA here: https://www.modalai.com/pages/rma

@aspen The landing detector in PX4 isn't perfect (obviously) so in this case it didn't detect the landing. I would map one of the switches to toggle between arm and disarm so that when the drone lands you can disarm via switch. Did you try the v1.16 package?

@aspen Can you provide the log file? There is a version of px4 v1.16 available here: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-mainline-px4_1.16.0-1.0.4-202509030932_arm64.deb

@Hunter-Scott If you delete all logs then fly you don't see any log files afterwards?
