Facing issue in booting Balena OS

Sharvin26 · May 9, 2019, 11:44am

I have downloaded the Balena OS for Beaglebone green wireless.

I have an sd card with a single partition ( Format Fat32 )

I am using Balena Etcher to Flash the operating system.

Now when I boot the Operating System I get the following error:

Hi @Sharvin26 could you try using the Beaglebone Black .dev image instead of the Green. This Beaglebone Black image will work on all variants of the beaglebone (except pocketbeagle) and is a newer version of the OS.

Sharvin26 · May 9, 2019, 11:52am

Which one should I use production or development?

shaunmulligan · May 9, 2019, 11:56am

While you are testing and developing I would recommend the development image. Also just to make sure, i are you just looking to use balenaOS with out the cloud service? or do you intend to use balenaCloud as well?

Sharvin26 · May 9, 2019, 11:58am

Right now I am just exploring the platform.

shaunmulligan · May 9, 2019, 12:00pm

Cool, welcome! If you are interested in the remote update and deployment side of things, you can look at this getting started as well https://www.balena.io/docs/learn/getting-started/beaglebone-black/nodejs/

Sharvin26 · May 9, 2019, 12:01pm

Thanks

shaunmulligan · May 9, 2019, 12:19pm

No problem! let us know if you have any more questions

Sharvin26 · May 9, 2019, 1:41pm

I downloaded the Beaglebone black image and flashed it directly on the sd card using Balena etcher. I am still facing the issue

Did you hold down the small black button marked s2 (located near the SD card slot) and power up the device by inserting the power or USB cable? You need to hold the button down to ensure the BB boots from SD card rather than internal eMMC.

Sharvin26 · May 9, 2019, 1:55pm

It is booting when holding the s2 switch.

Is there any way I can tell the Beaglebone to boot from Sd card ( like adding configuration in uEnv.txt )

shaunmulligan · May 9, 2019, 2:01pm

No unfortunately the way the OS is currently designed is that it will initially boot from SD card (when s2 button) is held down, it will then flash the balenaOS onto the devices internal eMMC and shut itself down, all the leds will go off. Then next time you power it on, it will be running balenaOS from eMMC.

Sharvin26 · May 9, 2019, 2:08pm

Okay, and what’s the default login credentials?
And everytime I add a sd card with balena os will it reflash the eMMC?

shaunmulligan · May 9, 2019, 2:11pm

on a development OS the default login creds are root and no password. It is designed to be used in a lab and obviously not for production use. On the production versions you can add a ssh key to the SD card before provisioning or you have access via the web dashboard on balenaCloud.

Sharvin26 · May 9, 2019, 2:17pm

When I ping the device I get following logs

➜ ping balena.local
  ping: cannot resolve balena.local: Unknown host

These are my serial logs:

root@balena:~# hostname
balena

Also, I cannot ssh into the OS. Logs:-

➜ sudo balena local ssh balena.local --host

shaunmulligan · May 9, 2019, 2:19pm

If your laptop is running linux can you do a avahi-browse -a to try discover the device? Or alternatively try sudo balena local scan it might be that it has a slightly different name for some reason.

Sharvin26 · May 10, 2019, 9:55am

I am facing trouble in some configurations on balena os:

Question 1:
By default, the system is mounted as read-only. Is there any way I can mount the system as read-write both.

Question 2:
I could successfully load the overlays dtbo that are present in the Balena OS by enabling them in uEnv.txt
Now I want to load a overlays dtbo file that doesn’t exist in Balena OS by default.
I have the dtbo with me How can I add that dtbo into /boot/overlays directory. As the root file system is mounted as read-only. I tried adding the dtbo by the mounting image from SD card and adding the DTBO in flash-rootfs partition ( /dev/sdc2 ) in /boot/overlays/myoverlay.dtbo
But When the image was flashed on the eMMC that dtbo was not present in that directory.

Question 3:
According to the documentation, balena os has a network manager. I have use connman previously for managing my network connections.

Now I have a use case:
I want my Beaglebone to have its own hotspot. For example, When I was having connman configured on my beaglebone my beaglebone AP was available in the network. I couldn’t find a solution to this situation.

Question 4:

Right now according to my understanding this command sudo balena local ssh mydevice.local --host ssh the beaglebone over a wireless network. How can I ssh using a usb for development purpose?

spanceac · May 10, 2019, 10:11am

Hi,

Answers to your questions:

mount -o remount,rw /
Now that you can mount the fs as RW you can copy your custom dtbo after flashing in the /boot folder. Please note that if you do a hostOS update, your custom dtbo will get vanished after update.

If you need the custom dtbo in the OS you can either build your own OS from sources and customize it, or sign-up for a custom device type.

https://www.balena.io/docs/reference/OS/network/2.x/#creating-a-hotspot
Not sure what you mean by ssh using a USB. Connect an USB to ethernet adapter to your board? Make the board act as a USB network interface?

Regards!

Sharvin26 · May 10, 2019, 11:09am

Question 1:

first I remounted the partition as writeable using mount -o remount,rw /

After that, I added the dtbo in /boot/overlays

custom_overlay.dtbo

Then I added the overlay into my uEnv.txt under /mnt/boot/

uboot_overlay_addr1=/boot/overlays/custom_overlay.dtbo

And rebooted the system then I get the following logs:

uboot_overlays: unable to find [mmc 1:2 /boot/overlays/custom_overlay.dtbo]...

Question 2:

Is there any guide for Beaglebone to build balena os from source with the custom dtbo? And can you share more about

sign-up for a custom device type.

Question 3:

Network Setup on balenaOS - Balena Documentation

When I turn on the hotspot it disconnects the wifi connection. I don’t want this behavior. I want Beaglebone to have its own access point and it can connect other wifi networks simultaneously.

Question 4:

Not sure what you mean by ssh using a USB. Connect a USB to ethernet adapter to your board? Make the board act as a USB network interface?

When I was using Debian on beaglebone I could ssh using command ssh debian@192.168.7.2. According to my understanding, IP was assigned to the USB interface. Can I do the same for the Balena OS?

Question 5:

I didn’t see anything related to logrotate and cron in my Host OS. Do I need to add this functionality in the container for the application that needs logrotate and cron jobs?
