i.MX Serial Download Protocol tool

imx-sdp

imx-sdp is a command-line utility that allows to boot NXP i.MX processors over Serial Download Protocol (SDP) via the USB interface.

This is a re-implementation of imx_usb_loader with the following design goals:

• Only implement the bare minimum to boot multiple stages over SDP (USB)
• Don't require configuration files

Invocation

Usage: imx-sdp [OPTION]... <STAGE>...

The following OPTIONs are available:

-h, --help  print this usage message
-p, --path  specify the USB device path, e.g. 3-1.1
-V, --version  print version
-w, --wait  wait for the first stage

The STAGEs have the following format:

<VID>:<PID>[,<STEP>...]
    VID  USB Vendor ID as 4-digit hex number
    PID  USB Product ID as 4-digit hex number

The STEPs can be one of the following operations:

write_file:<FILE>:<ADDRESS>
    Write the contents of FILE to ADDRESS
jump_address:<ADDRESS>
    Jump to the IMX image located at ADDRESS
