udynlink: a dynamic linker for ARM Cortex-M MCUs #Arm #Programming
udynlink is a dynamic linker for ARM Cortex-M MCUs. It compiles code into a binary blob that can be loaded and executed at runtime on the MCU. The binary blob can be either loaded into RAM or executed directly from the flash memory (execute in place). The dynamic linker can be used for various purposes, such as:
Use code that can run only from RAM (for example, code that manipulates the internal MCU flash memory, like a bootloader).
Speed up the execution of some of your code by running it from RAM instead of Flash.
Apply partial patches to your application (replace a part of the code by dynamically loading a newer version of that code).
Implement loaders for modules written in C for higher-level languages (like Lua, Python or JavaScript).

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
