Clone JLINK V9 ARM JTAG SWD Programmer Debugger Emulator with 20 Pin Cable

J-Link Debug Probe Cortex M0 M3 M4 M7 STM32 NXP Flash Download Keil IAR Embedded Firmware IoT Drone Robot

     The product is a clone Jlink v9 programmer. No technical support is provided regarding the product. The product package is opened and tested. It is shipped after being seen to work.

     This product is a J-Link V9 compatible clone ARM programmer and debugger (emulator). The black plastic case has a USB input at one end and a standard 20 pin (2x10) ARM JTAG connector at the other; it connects to the target board with the included 20 pin grey ribbon cable. It is powered from USB, no separate adapter is needed. It is recognized by the J-Link driver on the PC and programs and debugs ARM7, ARM9, ARM11, Cortex-M0, M3, M4, M7, Cortex-A5 - A9 and Cortex-R4 microcontrollers over JTAG or 2 wire SWD.

     According to sellers it runs on an STM32F205 controller; interface speed is up to approximately 15MHz and flash download speed up to 1MB/s. It works directly with Keil MDK, IAR EWARM and other IDEs supporting J-Link; J-Flash allows production flash programming and GDB Server allows debugging in Eclipse based environments.

     Its boxed design and long ribbon cable make it comfortable on the desk, in the lab and on the production line. It is a low cost solution for firmware development, flash programming and erasing / recovering locked microcontrollers on ARM based boards such as STM32, NXP LPC / Kinetis and Atmel SAM. It is not an original SEGGER product; for work requiring commercial support and a SEGGER license an original J-Link should be preferred.

Key features:

     JTAG and SWD in one probe: Both 4 wire JTAG and 2 wire SWD connections are made from the same 20 pin connector; serial trace output can be read from the target over SWO.

     Wide core support: Programs and debugs processors with ARM7, ARM9, ARM11, Cortex-M0, M1, M3, M4, M7, Cortex-A5 - A9 and Cortex-R4 cores.

     Fast download: According to seller values, up to approximately 15MHz interface speed and up to 1MB/s flash download speed.

     Common IDE support: Keil MDK, IAR EWARM and other IDEs supporting J-Link recognize the probe directly; no extra plug-in is needed.

     Boxed with cables: Housed in a black plastic case with a status LED; a 20 pin (2x10) ribbon cable and a USB cable are included.

Features:

• Product type: J-Link V9 compatible clone ARM programmer / debugger (emulator)
• Model: JLINK (V9 clone)
• Target interfaces: JTAG, SWD (2 wire serial debug), SWO / SWV

• Interface speed: up to approximately 15MHz (seller value; the original J-Link BASE is also limited to 15MHz)
• Flash download speed: up to 1MB/s (seller value)
• Main controller: STM32F205 (seller statement)
• Power: USB powered, no external power supply needed
• Target voltage sensing: works according to the target board voltage on VTref (pin 1)
• Software: J-Link driver, J-Link Commander, J-Flash, GDB Server, remote server (TCP/IP)
• IDE support: Keil MDK, IAR EWARM, Atollic TrueSTUDIO, Renesas e2studio and other IDEs supporting J-Link
• Operating system: Windows, Linux, macOS (J-Link software)
• Unlimited flash breakpoints support (seller claim)
• Multi device JTAG chain and adaptive clocking (RTCK) support
• Status indicator: 1 LED on the case
• Target connector: Standard 20 pin (2x10) ARM JTAG, 2.54mm pitch
• Material and colour: Black plastic case with USB and JTAG+SWD direction marks
• Cable colour and type: grey, 20 pin (2x10) ribbon cable, female IDC connector on both ends, pin 1 marked red

Usage information:

• Install the SEGGER J-Link Software and Documentation Pack on the PC, then connect the probe with the USB cable; select "J-LINK / J-TRACE" as the debugger in Keil or IAR.
• Plug the 20 pin cable into the JTAG connector on the target board with the red stripe on pin 1. Pin 1 (VTref) must be connected to the target supply voltage (usually 3.3V); without it the probe cannot see the target.
• For SWD on the 20 pin connector use pin 1 VTref, pin 7 SWDIO, pin 9 SWCLK, pin 15 RESET, pin 4 GND; connect pin 13 for SWO. Boards with a 10 pin 1.27mm connector need a separate adapter.

Application areas:

•  Embedded firmware development with ARM microcontrollers such as STM32, NXP LPC / Kinetis, Atmel SAM
•  Flash programming in production and service workshops (J-Flash)
•  Programming and debugging robot controller boards
•  Loading bootloader and firmware on drone flight controllers
•  IoT device and sensor node firmware development
•  Maintenance of industrial automation and control boards
•  Erasing and recovering read protected or locked microcontrollers
•  Embedded systems education in universities and labs
•  Run time monitoring and debugging over SWO (printf redirection)

Precautions:

•  This product is a clone J-Link V9; it is not an original SEGGER product and is not covered by SEGGER support or license. No technical support is provided for the product.
•  The J-Link software may offer a "firmware update" when connecting. On some clone probes the update can make the device unusable; do not confirm the update window.
•  Power the target board from its own supply where possible; connect VTref (pin 1) to the target logic voltage. Check the target voltage before using it on 5V logic targets.
•  Do not plug the 20 pin cable in reverse; the red stripe marks pin 1. Do not plug or unplug the cable while the probe and target are powered.
•  Operation with 64 bit cores such as Cortex-A53 / A57 / A72 and newer cores such as Cortex-M23 / M33 is not verified; a current original J-Link is recommended for these processors.
