![]() ![]() So it’s possible that the reson is not the clone, but faulty wiring, missing target power, or incorrect settings. As you seen above, for this solution you do not need any other st-link, you need only usb-uart adapter. PCB templates for prototyping at home are photoresist.svg and lut.svg, also you can convert PCB to any of appropriate formats using KiCAD. ![]() ![]() However, if the Segger driver refuses a clone, it writes something like “Faulty device”, and your error message is different. ST-link V2 schematic and PCB in kiCAD with initial firmware through UART. Support all ARM7/ARM9 core chips, as well as cortex M3, including Thumb mode. Considering the low price of the jlink edu mini, what is the point for a clone? IAR EWARM integrated development environment seamlessly connected JTAG Emulator. The J-Link board on the picture is definitely a clone, and Segger actively defends against clones. Based on a 32-bit RISC CPU, it can communicate at high speed with the supported target CPUs. ![]() It does not provide power for the target, just measures it. J-Link is a USB powered JTAG emulator supporting a large number of CPU cores. It’s an analog input, intended use is measuring the target power supply voltage. Also can someone explain what is jlink Target interface voltage “VIF” ![]()
