OpenOCD scripts for read STM32 firmware binary

Requirements

Linux

OpenOCD (Open On-Chip Debugger) is open-source software that interfaces with a hardware debugger's JTAG port. OpenOCD provides debugging and in-system programming for embedded target devices. OpenOCD provides the ability to flash NAND and NOR FLASH memory devices that are attached to the processor on the target system. Flash programming is supported for external CFI compatible flashes (Intel and AMD/Spansion command set) and several internal flashes (LPC2000, AT91SAM7, STR7x, STR9x, LM3 and STM32x).

OpenOCD was originally developed by Dominic Rath at the University of Applied Sciences Augsburg. The OpenOCD source code is now available through the GNU General Public License (GPL).

How to enter FEL mode on Lichee nano

If SPI flash isn't on the board, just remove the TF(microSD) card from the board and supply the power. It's the same if SPI flash is empty,

If your board have a SPI flash with preloaded image, pull D4(SPI CLK) down to GND. You can use the metal part of USB micro B or TF card slot as GND. Diagram is in the comment below. Thanks: @ernestp for the correction and providing a diagram.

Or you can use the special boot image [link]. Just write it to a TF card and boot.

Don't forget to remove the GND connection after entering FEL mode otherwise you will never be able to write the boot image to the SPI flash.

Diagrams

Markdown Preview Enhanced supports rendering flow charts, sequence diagrams, mermaid, PlantUML, WaveDrom, GraphViz, Vega & Vega-lite, Ditaa diagrams. You can also render TikZ, Python Matplotlib, Plotly and all sorts of other graphs and diagrams by using Code Chunk.

Please note that some diagrams don't work well with file exports such as PDF, pandoc, etc.

Flow Charts

This feature is powered by flowchart.js.

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

So you're writting a twitterbot and you need to authorize your application to post to the account. You need an access token and secret for the account you're posting to. If the posting account is the same account that owns the application, no problem, you just push the button on your application's settings page to make the keys. But if you want to post to a different twitter account, there's no UI on apps.twitter.com to authorize it. So I made this bare-minimum node server to run through the authorization process. There's probably a much better way to do this, so please let me know what that way is!

ignore this and go down to the comments for better solutions

You'll need a server with node.js!
Make sure your application has a callback URL specified in its settings page, even if it's just a placeholder. If there's nothing in the callback URL slot, this method of authorization won't work.
In authorize.js, fill in your application's consumer key and secret, and the domain on which you'll be running th
