Wyse 3040 USB3 front port can be used for USB Gadget ("device").

This probably applies to other Bay/Cherry Trail-based devices (Z8350).

Prerequisites

EFI shell - shellx64.efi → /EFI/BOOT/BOOTX64.EFI
setup_var.efi

Usage

Boot UEFI Shell

This is a quick list of cool payloads that can be pushed onto some common MCU boards to turn these them into actually useful everyday hacking tools.

STM32F1 / Bluepill
- blackmagic probe - SWD + UART adapter - https://medium.com/@paramaggarwal/converting-an-stm32f103-board-to-a-black-magic-probe-c013cf2cc38c - also a tip on how to use native UART bootloader
- bluepill_ch341a - CH341A-compatible device (SPI EEPROM + UART)
- i2c-star - I2C adapter (i2c-tiny-usb clone)
- versaloon - JTAG stuff
- DirtyJTAG - JTAG stuff
RP2040 / RPi Pico
- rp2040-i2c-interface - i2c-tiny-usb interface
pico-usb-io-board - general purpose USB to SPI/I2C/ADC/GPIO interface

Advanced Recursive Diffing™

Ever needed to diff two trees of files, while doing some preprocessing on modified files? Well - we've got a solution for you. Or rather... our long friend git has.

Turns out it's perfectly legal to just use git diff --no-index on directories outside of (any) git repository. With that, we can (ab-)use built in git diff per-path/extension preprocessing feature.
