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).

eMMC reballing

The same technique should work well with other (bigger) ball sizes too, however there are rarely issues when handling bigger packages and less care is usually needed there.

The technique uses premade solder balls, not solder paste.

Equipment:

• Solder balls of correct size (0.3mm for eMMC)
• Stencil to hold the balls with correct configuration for the package eg eMMC 153/169 standard stencil

Reconfigure your RPi Locales

First you need to install the locales you want:

sudo dpkg-reconfigure locales

Then refresh your current environment:

Approaching a Xamarin.Android Bindings Case

1. Investigation

One of the best ways to investigate a problematic Xamarin.Android Binding is to first ensure you have the proper tooling available:

• Diagnostic MSBuild Output Enabled(Instructions)
• Java Decompiler(http://jd.benow.ca/)
• .NET Decompiler(https://www.jetbrains.com/decompiler/)
• Binding SDK Documentation
