Command line

Command line and scripting reference for Jumpstarter.

Jumpstarter today comes as a commandline tool that allows you to interact with the test-harness via the driver architecture.

Jumpstarter CLI

Most commands accept a device-id. A device-id can be either the serial number of the device, or the device name.

All commands accept the following flags

  -d, --driver string    Only devices for the specified driver
  -h, --help             help for jumpstarter



This command will list all the devices that are currently available throught the various test-harness drivers.

$ jumpstarter list-devices
Device Name	Serial Number	Driver			Version	Device		Tags
orin-agx-00	e6058a05	dutlink-board	0.05	/dev/ttyACM2	orin-agx, orin, 64gb
xavier-nx-00	e6058905	dutlink-board	0.04	/dev/ttyACM1	nvidia, xavier-nx, nvidia-xavier, arm64, 8gb
visionfive2-00	031da453	dutlink-board	0.04	/dev/ttyACM0	rv64gc, rv64, jh7110, visionfive2, 8gb


This command lists all the drivers that are currently available.

$ jumpstarter list-drivers
	OpenSource HIL USB harness (
	enables the control of Edge and Embedded devices via USB.
	It has the following capabilities: power metering, power cycling, and serial console
	access, and USB storage switching.

run-script script.yaml

This is probably the most useful jumpstarter command today. It runs a jumpstarter script, which will select a device based on the selector tags, and execute all the steps of the script. Once finished or if an error occurs the cleanup section of the script will be run.

$ jumpstarter run-script script.yaml
See the scripting section for a detailed guide on how to write scripts and examples.

set-control device-id

Set a control signal from the test-harness to the device. This is used to control signals on the DUT or trigger external hardware like video generators, simulated sensors, fault injectors, or other necessary devices.

$ jumpstarter set-control orin-agx-00 A LOW

The signal names and output modes depend on the test-harness being used. See the dutlink-board section for more details.


set-disk-image device-id

Set the disk image to be used for the DUT. This is used to write the disk image to the DUT’s attacheable storage device. Images can be a raw disk image or an ISO image.

$ jumpstarter set-disk-image orin-agx-00 my-system-image.raw
  -o, --offset-gb uint   Offset in GB to write the image to in the disk

You can limit or filter the devices found by jumpstarter for image writing by using the storage_filter config. This configuration is stored into the test harness board and will be used by jumpstarter to filter the devices found.

i.e. for using only /dev/disk/by-id/usb-SanDisk_Extreme_Pro_52A456790D93-0:0

you could set: jumpstarter set-config device-id storage_filter Extreme_Pro_52A456790D93-0:0

This is also useful if your USB disk exposes multiple sub-devices.

attach-storage device-id

This command attaches the storage device to the DUT. This is normally required to boot the DUT.

$ jumpstarter attach-storage orin-agx-00
💾 Attaching storage for orin-agx-00 ... done

detach-storage device-id

This command detaches the storage device to the DUT.

$ jumpstarter detach-storage orin-agx-00
💾 Detaching storage for orin-agx-00 ... done


power on|off|force-on|force-off|rescue device-id [-t] [-r] [-a]

This command manipulates the power status of a device


$ jumpstarter power off orin-agx-00
🔌 Powering off orin-agx-00... done

The different power actions available are:

onPower on the device using the power_on profile from configuration
offPower off the device using the power_off profile from configuration
force-onPower on the device using only power, ignoring the profile from configuration
force-offPower off the device using only power, ignoring the profile from configuration
rescuePower on the device using the power_rescue profile from configuration
  -a, --attach-storage   Attach storage before powering on
  -t, --console          Open console terminal after powering on
  -r, --reset            Reset device after power up

For information on how to configura the power profiles (power_on, power_off, power_rescue), please see the set-config section.

reset device-id

Use the reset signal on the device to reset it, only open drain signal is supported (pulling low + high impedance) at this time.

$ jumpstarter reset orin-agx-00
⚡ Toggling reset on orin-agx-00


console device-id

This command provides a serial console to the DUT, it will connect to the serial console of the DUT and allow you to interact with it.

$ jumpstarter console orin-agx-00
Looking up for out-of-band console:  TOPOD83B461B-if01
💻 Entering console: Press Ctrl-B 3 times to exit console
[0000.219] I> FUSE_OPT_PVA_DISABLE = 0x00000000

create-ansible-inventory device-id

This command interacts with the console of the DUT which must be logged in with a user andcreates an ansible inventory file for the DUT. This ansible inventory can be used to run ansible playbooks against the DUT.

$ jumpstarter create-ansible-inventory orin-agx-00

This command accepts the following extra flags:

  -k, --ssh-key string   The ssh key to use for the ansible inventory file
  -u, --user string      The user for the ansible inventory file (default "root")

run device-id command

Sends a string via the serial console to the DUT and waits for a response which is then written to stdout.

$ ./jumpstarter/jumpstarter run orin-agx-00 "ls -la"
Looking up for out-of-band console:  TOPOD83B461B-if01

In the above example the system had already been logged in via the console.

  -w, --wait int        Wait seconds before trying to get a response (default 2)


set-name device-id name

Changes device name. This is used to set a name for the test-harness device. This should make devices easier to identify.

$ jumpstarter set-name e6058a05 orin-agx-00
✍ Changing device name for e6058a05 to orin-agx-00 ... done

set-tags device-id tag1 [tag2 …]

Changes device tags, pass one argument per tag. This is used to set tags for the test-harness device which can be used to select specific devices from a script or some commands.

$ jumpstarter set-name orin-agx-00 orin-agx orin 64gb
✍ Changing device name for orin-agx-00 to orin-agx ... done

get-config device-id [key]

Shows the device configuration parameters stored on the test-harness board. If a key is provided only the value for that key will be shown.

$ ./jumpstarter get-config orin-nx-00 power_on

Otherwise a yaml list of all parameters will be shown.

$ ./jumpstarter get-config orin-nx-00
name: orin-nx-00
tags: orin-nx-00,orin,orin-nx,16gb
power_on: p1,bL,w5,bZ
power_off: p1,bL,w5,bZ,w10,bL,w110,bZ
power_rescue: p1,bL,w1,bZ,w1,aL,rL,w1,rZ,w1,aZ

set-config device-id key value

Changes a device configuration config parameter (see get-config).

if values is "" the config will be deleted.

usb_console config parameter

Changes device name for out of band USB console. Some devices expose a console only via USB and the console is not accessible via pins. This command allows you to set a matching string for the USB console of the device.

Jumpstarter will try to find the USB console device by matching the string provided with this command when trying to communicate with the device via the console.

$ jumpstarter set-usb-console orin-agx-00 TOPOD83B461B-if01
✍ Changing usb_console name for orin-agx-00 to TOPOD83B461B-if01 ... done

power_on/off/recue parameters

These parameters are used to configure the power sequences, they are a comma separated list of commands to be executed by the test-harness board to perform the power on/off/rescue of the device.

The commands are:

  • p1: power enable
  • p0: power disable
  • aL: pin A low
  • aH: pin A high
  • aZ: pin A high impedance
  • bL: pin B low
  • rL: pin RESET low
  • rH: pin RESET high
  • rZ: pin RESET high impedance
  • wN: wait N*100 ms, where N is a natural number.

Some examples of configuration for orin-nx/orin-agx devkit boards:

Touch power button for 500ms:

power_on: p1,bL,w5,bZ

Touch power button for 500ms (to make sure we start from ON), then touch for 11s.

power_off: p1,bL,w5,bZ,w10,bL,w110,bZ

Touch power button for 500ms (to make sure we start from ON), then assert A (recovery), then assert the reset signal, and wait 500ms, then deassert reset, wait 500ms, deassert A (recovery). This should put the jetson device into recovery mode.

power_rescue: p1,bL,w5,bZ,w1,aL,rL,w5,rZ,w5,aZ

where pin A is “REC” and pin B is “PWR” on the orin-agx/orin-nx boards.
