How to Upgrade STLink Firmware on Apple M1 Machine

STLink Upgrade software is written in Java. As of the date this gist was initially written, it did not seem to work with Java natively installed on Apple M1. It requires x86_64 architecture execution under Rosetta.

This guide is about installing Java OpenJDK 17 support via Homebrew x86_64, on Apple M1 machine, in order to be able to run STLinkUpgrade.jar software by ST Microelectronics.

STLink Upgrade software package can be obtained from:

Install Homebrew for x86_64 Architecture

It is similar to installing Homebrew natively, with added arch --x86_64 prefix before the command line:

How to SSH into Windows 10 or 11?

The latest builds of Windows 10 and Windows 11 include a build-in SSH server and client that are based on OpenSSH. This means now you can remotely connect to Windows 10/11 or Windows Server 2019 using any SSH client, like Linux distros. Let's see how to configure OpenSSH on Windows 10 and Windows 11, and connect to it using Putty or any other SSH client.

OpenSSH is an open-source, cross-platform version of Secure Shell (SSH) that is used by Linux users for a long time. This project is currently ported to Windows and can be used as an SSH server on almost any version of Windows. In the latest versions of Windows Server 2022/2019 and Windows 11, OpenSSH is built-in to the operating system image.

Boot Linux or OpenBSD on the PowerBook G4 (PowerPC/ppc32)

Creating the USB sticks

Use an older USB 2.0 stick, newer ones will most certainly not work.

sudo dd if=debian-11.0.0-powerpc-NETINST-1.iso of=/dev/sda1 status=progress # Or use GNOME Disks, Etcher etc.

Using cec-client on a Raspberry Pi

Most modern HDMI connected devices support Consumer Electronics Control (CEC). It allows devices to send commands to each other, typically to get the TV to switch input and control volume. If you have ever turned on a Game Console and had your TV automatically change input to that device you have seen CEC in action. It is very convenient and useful, sort of a universal remote that works.

Every manufacturer seems to have it’s own branding of CEC (e.g. Samsung Anynet+, LG SimpLink, Sharp Aquos Link) but it may need to be enabled. Check your manual for details.

Using a Raspberry Pi connected to a TV that supports CEC, you can use the command line cec-client application to control the inputs and the TV itself. These are notes on how to use cec-client and understand the different options.
