Segger offers the capability to upgrade the firmware on the BBC micro:bit DAPLink to a J-Link OB (On Board). This firmware makes the on-board debug solution on the BBC micro:bit compatible to J-Link, allowing users to take advantage of all J-Link features such as ultra fast flash download and debugging speeds and the free-to-use GDBServer as well as application development using an IDE.
“Adding J-Link debug capabilities to the BBC micro:bit broadens its exposure to an even larger audience. The micro:bit eco-system is improved significantly by making professional tool options available to developers,” says John Leonard, Product Marketing Manager, Nordic Semiconductor.
J-Link is supported in all major IDE’s; IAR EWARM, Keil MDK, Rowley Crossworks, Segger’s own Embedded Studio and other Eclipse/GDB based offerings. This gives students developers flexibility in their choice of IDE’s without compromising on the superior download speed to RAM and Flash that J-Link technology offers.
