Sentinel VOXL2 Microhard not running

[rohitpillai]

Here is the output -

If I try to SSH using this IP address, it takes me to this and not VOXL2 -

On the other drones it is usually eth0 for the Microhard connection. Why is it defaulting to usb0?

[rohitpillai]

Okay typing in bash takes me to VOXL2. However, it is not setting the static IP address that I want it to set, which is 192.168.168.60

@rohitpillai I'm still playing around to figure out exactly what is going wrong but here are a couple answers:

That SSH session is the VOXL2, SSH just doesn't put you in the bash shell by default, if you run bash it should give you the expected voxl terminal you're used to.

The reason why it is showing up as usb0 and not eth0 is because the Microhard add-on board you're using is a newer flavor than the others "M0048-2" vs "M0048-1" (the silk screen may not reflect that correctly). This newer flavor removes the LAN7500 chip and uses a slightly different driver to enable comms between the chips.

This functionality is new to voxl-modem as well which is why you're running into this bug, you're one of the first people to actually have one of these new boards in hand.

[rohitpillai]

Oh cool! Is there anything I can do to help from my side to figure this out?

[tom]

@rohitpillai I will let you know if I need anything from you. I'm screwing around with the voxl-modem source code right now to try to figure out how to fix the issue. I think I've already found a couple things that could resolve it.

I'll update once I get it going, I may generate a new voxl-modem deb package for you to try out

[rohitpillai]

Sounds good!

[tom]

@rohitpillai I believe I have fixed the issue. voxl-modem was jumping ahead and assuming that the modem had enumerated before it had which would cause some of the commands to never be run.

I have generated a new dev package for you to try out, the download link is:

404 Not Found

(voxl-packages.modalai.com)

You can take a look at the source code changes here: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-modem/-/commit/0cc330f8fcd6cafc97b80412dfe9994b8389e90b

In order to try this package out, do the following:

• download the voxl-modem_0.15.2-202206291955_arm64.deb package using the above link
• push the package to your VOXL2 in the directory you'd like (I'll use /data) using:

adb push voxl-modem_0.15.2-202206291955_arm64.deb /data

• Force remove the voxl-modem package on board:

adb shell

dpkg --purge --force-all voxl-modem

• Install the new dev package:

cd /data

dpkg -i voxl-modem_0.15.2-202206291955_arm64.deb

• Re-run voxl-configure-modem and choose the IP to your liking

Verify that the network interface comes up and the IP is what you expect with ifconfig

Try a couple reboots to confirm that the expected behavior is consistent.

Let me know if you need any clarity on the above and let me know the outcome of your tests.

The usb0 network interface won't come up immediately after reboot (may take 10-15 seconds) for it to enumerate

[rohitpillai]

After a couple of reboots I am getting the same behaviour. It works as it should now! Thanks!

[tom]

@rohitpillai Woot! Thank you for all of your help! I will go ahead and merge this into master so that it will make it into the next release.

@tom Hey Tom,

I am noticing this issue of microhard not having a static ip on my system as well.

It appears I am on a later version than the one in the post. Is the voxl-static-ip service now the preferred way to have a static ip?

[wilkinsaf]

@wilkinsaf Code is still there

[wilkinsaf]

@wilkinsaf But ip still is not what is in the config file

ip address:

config file:

[tom]

@wilkinsaf Interesting, give voxl-static-ip a try and see if it helps. I have yet to integrate that directly into voxl-modem. We have a systemd service setup for it, so I would go ahead and modify /usr/bin/voxl-static-ip and then enable it's service systemctl enable voxl-static-ip

[wilkinsaf]

@tom I did, but i had to add in a huge sleeper and have it After=voxl-modem.service

since the voxl-modem is a python script (thank you for that) I am just doing some caveman debugging. will post progress

[tom]

@wilkinsaf voxl-static-ip is pretty "dumb" as it doesn't check to see if the interface is actually up before trying to modify the IP so that's probably the reason why you need the big sleep, but I'm sure you figured that out already.

[wilkinsaf]

@tom Yeah. I think I figured it out

My uname has "m0054". It uses eth0 as interface instead of usb0. i dont see code for setting the ip for eth0. What is weird is that I also see usb0 come up as an interface. But I am going to add some code here to hopefully fix that. Will make a branch or something if it is useful for someone else

[tom]

@wilkinsaf Do you have any other type of network connection going? WiFi? Ethernet?

I can try to copy your setup, so you've got a VOXL2 w/ Microhard add-on? anything else important connected? mipi cameras and such wouldn't affect this

[tom]

@wilkinsaf Also a voxl-version would be helpful to see. To give you some background on why this part is a little confusing, on newer builds of Microhard add-ons we had to change out a chip due to supply shortages and so the newer Microhard add-ons will be handled as "usb0" instead of "eth0".

[tom]

@wilkinsaf Oh also, while I'm asking you things, the output of the following would be helpful as well:

dmesg | grep eth0

dmesg | grep usb0

[wilkinsaf]

@tom

No other wifi or ethernet. I am connected with adb.

VOXL2 with microhard
cameras: stereo, tracking, hires (although my config only has the tracking and hires turned on rn)
