Balena Config Inject Failing for Local TX2 Built

Product support balenaOS
1

Hello! I’m trying to test a local build of the jetsontx2 image for a customer carrier board.

See my PR here for context: https://github.com/balena-os/balena-jetson/pull/71

When I try to run the local configure command below, I get the error listed. Can anyone help me figure out how to insert the config.json so I can test this image?

Command
balena config inject testbed-tx2.config.json --type jetson-tx2 --drive /dev/disk2

Error
Unsupported filesystem.

Additional information may be available by setting a DEBUG=1 environment

variable: “set DEBUG=1” on a Windows command prompt, “$env:DEBUG = 1” on

powershell, or “export DEBUG=1” on Linux or macOS.

Hi, you need to make sure the “–drive” parameter points to the correct location: https://www.balena.io/docs/reference/balena-cli/#config-inject-file . Have you mounted the OS image you built?

4

Hey there! No I was just trying to do it from the SD card. What’s the best way to mount the image file?

5

losetup --show -fP

6

losetup --show -fP

7

losetup --show -fP YOUR_IMAGE_FILE

and then you can use the yielded loop device

8

Ok perfect that worked. Now I unmount and then use the same image file?

9

Yes, unmount and use that image which you just modified

10

Perfect! I unmounted with this command: sudo losetup -d /dev/loop19

Is that the correct way?

11

Yes, that is it

12

Cool. Thank you so much for your help!
