Developers that use any ARM-based platform would like a helping hand debug issues may be interested to know that the Segger J-Link EDU Mini, JTAG/SWD Debugger is now available to purchase directly from the ad approved online store price that $19.95
The J-LINK EDU Mini is a version of the J-Link EDU in a reduced form factor measuring just 18mm x 50mm similar to the USB stick with identical functionality for Cortex-M based targets. Features of the J-LINK EDU Mini debugger include:
– Unlimited Breakpoints – The unlimited breakpoints in flash memory feature can be used free of charge for evaluation. The evaluation period is not time limited. For commercial use a separate license is required.
– Free Software Updates – As a legitimate owner of a SEGGER J-Link, you can always download the latest software free of charge. Though not planned and not likely, we reserve the right to change this policy. Note that older models may not be supported by newer versions of the software. Typically, we support older models with new software at least 3 years after end of life.
– Supports concurrent access to CPU by multiple applications – J-Link allows multiple applications to access a CPU at the same time. This has numerous applications. J-Link commander can be used in parallel to a debugger, a tool to communicate via DCC can be used in parallel to a debugger or a visualization tool such as Micrium’s u/C-Probe or SEGGER’s kernel viewer embOSView.
– Cross-platform support – Runs on Windows, Linux, Mac OS X. The MAC and Linux versions are fully usable, but limited to the following components: J-Link Commander, command line GDBServer, shared library (DLL-equivalent)
– Licensing and Support : J-Link EDU Mini may only be used for non-commercial purposes. J-Link EDU Mini does not include support. However you may submit your question to the SEGGER Forum
A proper JTAG/SWD HW debugger can make debugging more of a pleasure and less of a pain. It allows you to program your devices at the click of a button, read or write memory addresses or registers on a live system, temporarily halt program execution at a given location or condition, and much more. Essentially, it’s a direct window into what’s going on inside your MCU at any given moment, giving you a level of access and control that’s not easy to replicate with other debugging methods.
