OpenOCD scripts for read STM32 firmware binary
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).
| Task: | |
| Access OpenVPN or any Service on Home Network from Public Networks (Hotel) without configuring router and without static IP | |
| Step 1: | |
| Install OpenVPN on any device connected to Home Network (Raspberry mychoice with pivpn) | |
| - Change default OpenVPN protocol from UDP to TCP (Cloudflare doesn't support UDP) | |
| - Make a note of TCP port number (default is 443) | |
| - Grab the OpenVPN client config file | |
| Step 2: | |
| Install Cloudflared on Raspberry PI | |
| - Create a tunnel |
Goal: Emulate a Raspberry Pi with QEMU in order to run the Raspbian O/S (based on Debian Linux).
The current setup is not ideal. For one thing, the maximum RAM allowed using the "versatile-pb" firmware is 256 Mb. In addition, only the most basic peripherals, a keyboard and mouse, are supported.
A number of articles have been written on this topic. Most are outdated, and the few recent ones are missing key information.

This note describes the configuration of an ATtiny85 based microcontroller development board named Digispark and similar to the Arduino line. It is available in many online marketplaces for roughly 1 dollar (e.g., Ebay, Amazon, AliExpress) and is shipped fully assembled, including a V-USB interface (a software-only implementation of a low-speed USB device for Atmel's AVR microcontrollers). Coding is similar to Arduino: it uses the familiar Arduino IDE and is already provided with a ready-to-use bootloader (
