👑 NAME 👑

uuu — Freescale/NXP I.MX Chip image deploy tools 💖

✨ DESCRIPTION ✨

okay bestie, hydrate, sit down, because we're about to talk about your new favorite little deploy gremlin.

uuu is the Universal Update Utility for nxp imx chips -- lib1.5.243 🦋

Here's the whole shape of her:

uuu [-d -m -v -V -bmap -no-bmap] <bootloader|cmdlists|cmd>

And the three things you can hand her, in order of "what even":

bootloader — download bootloader to board by usb. that's it, that's the job 💅
cmdlist — run all commands in cmdlist file. If it is path, search uuu.auto in dir. If it is zip, search uuu.auto in zip.
cmd — Run one command, use -H see detail. example:

SDPS: boot -f flash.bin

🎀 the flags (the moment) 🎀

-d — Daemon mode, wait for forever. she's committed, she's not leaving 🫶
-v, -V — verbose mode, -V enable libusb error\warning info
-dry — Dry run mode, check if script or cmd correct. no cap, peek first
-bmap — Try using .bmap files even if flash commands do not specify them
-no-bmap — Ignore .bmap files even if flash commands specify them
-force-ctrl — Force HID transfer use control endpoint
-m <usbpath> — Only monitor these paths. -m 1:2 -m 1:3
-ms <serial_no> — Monitor the serial number prefix of the device using 'serial_no'.
-t <timeout> — Timeout second for wait known usb device appeared
-T <timeout> — Timeout second for wait next known usb device appeared at stage switch
-e <key=value> — set environment variable key=value
-pp <ms> — usb polling period in milliseconds
-dm — disable small memory

🌸 the other modes, the icons 🌸

uuu -s — Enter shell mode. uuu.inputlog record all input commands. and then, lowkey the best part: you can use "uuu uuu.inputlog" next time to run all commands 🔥
uuu -udev — linux: show udev rule to avoid sudo each time uuu
uuu -lsusb — List connected know devices
uuu -IgSerNum — Set windows registry to ignore USB serial number for known uuu devices
uuu -h — show general help
uuu -H — show general help and detailed help for commands

💅 tab completion, because we're fancy 💅

Enjoy auto [tab] command complete by put below script into /etc/bash_completion.d/uuu:

  _uuu_autocomplete()

       {

       COMPREPLY=($(/usr/bin/uuu $1 $2 $3))

       } complete -o nospace -F _uuu_autocomplete  uuu

then you get the little [?25h moment (yes bestie that stray escape-sequence-looking thing is just sitting there in the page, we don't question her 💀).

🌈 and then she does it AGAIN 🌈

okay so the page literally repeats this whole entire block a second time — iconic, unbothered, no notes. here's the round two recap, every single thing intact, promise, fr fr:

the flags, again, because she said so:
