STM32 development entirely on Linux

Summary

The stlink project replaces vendor-specific Windows tools with free compile, flash and debug workflows for STM32 Discovery boards. The board uses an ARM Cortex-M3. The manufacturer did not support Linux natively at the time.

Ideas

  • stlink talks to the integrated debug adapter over USB.
  • GDB transfers programs and examines the controller.
  • A Blink example checks the toolchain and hardware.

Insights

  • Open tools free development boards from being tied to vendor IDEs.
  • A minimal hardware test separates toolchain errors from application errors.

Recommendations

  • Automate build, flash and test in one script.
  • Keep a known working Blink build.

Several Linux kernels run without a hypervisor

Hackaday presents Multikernel Linux, in which a host kernel divides up the hardware and starts further independent Linux kernels directly on bare metal. The project is called Multikernel Linux. It is not the historical microkernel-based MkLinux.

Why Linux applications are hard to distribute

Hackaday describes the multitude of distribution packages, language managers, third-party sources, AppImage and Flatpak as a burden for application authors. The Fresh editor serves as a concrete example. APT, AUR, Homebrew, AppImage and Flatpak are named.

Cloudflare hits the limits of the Linux network stack

Hackaday describes Cloudflare’s attempt to redirect TCP connections for soft unicast and why a simple local proxy ultimately proved more robust. Cloudflare uses anycast extensively for its services. TCP_REPAIR is normally used to migrate connections.
