Please help us test our new micro:bit firmware 🧪

Hello micro:bit testers. We have a new beta release of the micro:bit V2 firmware (DAPLink) with improvements we think you'll like, and we need your help testing them before it is launched.
 

Download the firmware for micro:bit V2

What's in this beta release? 


The main feature is faster flashing! 🚀
Drag & drop for a hex file onto the `MICROBIT` drive can be up to 25% faster.

There are also bug fixes and stability improvements.

There are downloads for V2.00 and V2.2x. You can learn more about these versions and how to identify your micro:bit in the knowledge base.

What is the micro:bit firmware?

The BBC micro:bit has two on-board microcontrollers, the “target” runs the your programmes, and the “interface” is responsible for the USB and flashing capabilities.

The micro:bit firmware runs in the "interface" microcontroller and it's powered by the DAPLink project.

For the code-curious amongst you, this beta is built from this tag: v0258-beta3

What needs testing?🔬

On micro:bit V2.0 and V2.2 the main feature to test is flashing with the MICROBIT drive and the Online MakeCode and Python Editors.

For micro:bit V2.0 specifically, we've also changed the toolchain to use the open source GCC compiler suite, so that could affect all of the micro:bit firmware features:
  • Drag & drop flashing
  • Serial communications
  • WebUSB flashing and serial
  • Data logging
We think we’ve fixed all the bugs usually introduced with a toolchain port but, as it affects the entire code-base, other bugs could be lurking in corner cases associated with systems we can't test on. Which is why your help is so invaluable!
