I’ve never understood how they stay in business. Dirt cheap SWD programmers work with pretty much any arm chips and give you all the debugging features like breakpoints over just 2 wires.
- callmemclovin 5y agoJust did a quick search for JTAG debuggers on Aliexpress, and the majority seem to be clones of Segger J-Links, so yeah... it's easy to produce the (simple) hardware and sell for cheap if you just steal the software, it's the same with Saleae Logic Analyzers.
- NavinF 5y agoThe software (OpenOCD) is free and open source. Alternatively you could use a programmer that doesn’t require any software and just exposes a GDB server over a tty: https://1bitsquared.com/products/black-magic-probe https://1bitsquared.com/products/black-magic-probe
