jumpstarter-driver-ridesx 0.8.1

Jumpstarter driver for Qualcomm RideSX

RideSX driver

jumpstarter-driver-ridesx provides functionality for Qualcomm RideSX devices, supporting fastboot flashing operations and power control through serial communication.

This is mainly tailored towards images that were produced using automotive-image-builder:

automotive-image-builder build --target ridesx4 --export aboot.simg --mode package manifest.aib.yml ridesx.img

Installation

:substitutions:
$ pip3 install --extra-index-url {{index_url}} jumpstarter-driver-ridesx

Configuration

The RideSX driver supports two main components:

Storage and Flashing Configuration

Example configuration for the RideSX driver:

  storage:
    type: "jumpstarter_driver_ridesx.driver.RideSXDriver"
    config:
    children:
      # fastboot management serial port
      serial:
        type: "jumpstarter_driver_pyserial.driver.PySerial"
        config:
          url: "/dev/serial/by-id/usb-QUALCOMM_Inc._Embedded_Power_Measurement__EPM__device_98000205101B0224-if01"
          baudrate: 115200
  power:
    type: "jumpstarter_driver_ridesx.driver.RideSXPowerDriver"
    config:
    children:
      serial:
        type: "jumpstarter_driver_pyserial.driver.PySerial"
        config:
          url: "/dev/serial/by-id/usb-QUALCOMM_Inc._Embedded_Power_Measurement__EPM__device_98000205101B0224-if01"
          baudrate: 115200
  serial:
    type: "jumpstarter_driver_pyserial.driver.PySerial"
    config:
      url: "/dev/serial/by-id/usb-FTDI_Qualcomm_AIR_8775_AI208U7YXA-if01-port01"
      baudrate: 115200

CLI usage

$ jmp shell -l board=qc-ridesx4
# Flash the device using the artifacts from automotive-image-builder, this uses 3 partition file systems
$$ j storage flash --target system_a:rootfs.simg --target system_b:qm_var.simg --target boot_a:aboot.img
$$ j power on
$$ j serial start-console

By default the device is powered off after flashing. Use --no-power-off to leave it on.

Config parameters

RideSXDriver

Parameter	Description	Type	Required	Default
storage_dir	Directory to store firmware images and temporary files	str	no	/var/lib/jumpstarter/ridesx

API Reference

RideSXClient

.. autoclass:: jumpstarter_driver_ridesx.client.RideSXClient()
    :members: flash, flash_images, boot_to_fastboot, cli

RideSXPowerClient

.. autoclass:: jumpstarter_driver_ridesx.client.RideSXPowerClient()
    :members: on, off, cycle, rescue, serial

Usage Examples

Flash Single Partition

# Flash a single partition (paths must exist; flash runs fastboot on the exporter)
ridesx_client.flash("/path/to/boot.img", target="boot")

Flash Multiple Partitions

# Flash multiple partitions
partitions = {
    "boot": "/path/to/boot.img",
    "system": "/path/to/system.img",
    "userdata": "/path/to/userdata.img"
}
ridesx_client.flash(partitions)

Flash with Compressed Images

The driver automatically handles compressed images (.gz, .gzip, .xz):

# Flash compressed images - decompression is automatic
ridesx_client.flash("/path/to/boot.img.gz", target="boot")

Power Control

# Turn device power on
power_client.on()

# Turn device power off
power_client.off()

# Power cycle the device
power_client.cycle(wait=5)  # Wait 5 seconds between off/on

Features

• Fastboot Support: Automatically detects fastboot devices and flashes partitions
• Compression Handling: Supports automatic decompression of .gz, .gzip, and .xz files
• Power Control: Serial-based power control with on/off/cycle operations
• Storage Management: Built-in storage for firmware images with upload/download capabilities
• Serial Communication: Direct access to underlying serial interface for custom commands
