Multilink Overview

Multilink debug probes allow a PC access to the Background Debug Mode (BDM) or JTAG interface on wide range of ARM Cortex and 8-16-/32-bit devices, in order to halt normal processor execution and use the PC to control the processor. The user can then directly control the target’s execution, read/write registers and memory values, debug code on the processor, and program internal or external FLASH memory devices. 

Supported manufacturers include NXP, STMicroelectronics, Cypress, Infineon, Silicon Labs, and many others. Multilink connects between a USB port on a Windows machine and the standard debug connector on the target. Microcontrollers are supported via the multiple headers located under a flip lid on the Multilink case. Ribbon cables suitable for a variety of architectures are included.

Software Licenses/Compatibility

PEmicro's current software licenses (purchased separately) are hardware-based, meaning they are installed permanently onto a single hardware interface, such as a Multilink. Newly purchased Multilinks support these licenses, however users wishing to install a license on an older Multilink should read our blog posts regarding PROG licensing and ICD/PKG licensing to be sure their Multilink will support the license.  

Please note: Multilink debug probes do not include any software licenses by default, as there are myriad options regarding the device architecture and utility of software that the user might require. Users most often purchase a version of PEmicro's PROG programming software that is compatible with their device architecture. ICD debugger software and PKG software packages are available as well. Users can also create custom solutions with UNIT library routines. There is support for Multilink in many NXP and other third party tools, such as MCUXpresso IDE and MCUXpresso for Visual Studio Code, or STMicroelectronics' STM32CubeIDE. Click for a listing of compatible 3rd party ARM-based IDEs. In addition, ARM-based Eclipse IDEs are compatible, with the appropriate GDB Server plug in



Multilink Models & Features

Models

There are 3 models of Multilink:

 MULTILINK ACP  MULTILINK UNIVERSAL LC  MULTILINK UNIVERSAL FX 

Standard Features

All Multilink debug probes offer these standard features:

  • USB interface from PC to Multilink allows for fast, easy programming and debugging -- with the ease and compatibility of the USB interface.
  • Draws power from USB interface-- no separate power supply required (draws less than 1mA from the target).
  • Works with target voltage: 1.8V-5.25V
  • Supports JTAG daisy chaining of multiple ARM MCUs
  • ARM device support includes both the JTAG and SWD protocols
  • Includes USB cable, Type A Male to Type B Male, 6-ft.

"Universal" Features

 MULTILINK UNIVERSAL LC  and  MULTILINK UNIVERSAL FX  also include these features:

  • Pipelined programming algorithms for some Power Architecture families that dramatically increase programming speed.
  • Auto-frequency detection + trimming capabilities for HCS08 devices
  • Auto-frequency detection for HC(S)12(X) devices.
  • Generates programming voltage on RESET line for RS08 devices.
  • Target Frequency: 16Khz-50Mhz (applies to HCS08, RS08, CFV1, S12Z, or HCS12X only)

Advanced Features

 MULTILINK UNIVERSAL FX  supports these additional advanced features:

  • High-speed USB interface from PC to Multilink allows for fast, easy programming and debugging -- up to 10X faster than the other Multilink models.
  • Can be used to power target MCU:
    • Target Voltage: 3.3V, 5.0V
  • I/O line clamping for added protection

Multilink Universal FX Performance Note

The exceptional performance increases seen with the USB Multilink Universal FX are limited to synchronous architectures: ARM devices, Kinetis, S32, MPC55xx-577xx (& STMicroelectronics SPC5), Coldfire V2-V4, DSC, MPC5xx/8xx, and HC16/683xx.

No-Cost Software Features

1) PEmicro's "UNITACMP Library SDK for ARM Cortex-M processors" is free to download. This allows the user to create an application which can fully control the execution of an embedded processor via Multilink debug probes or Cyclone programmers.

2) PEmicro's no-cost GDB Server for ARM devices (Eclipse plug-in) includes the following powerful features:

  • Real-Time Expression View 
    This view gives the user the ability to view variables and memory while a target ARM device is running. Sometimes the process of halting the target masks a bug. Sometimes, in order to reproduce a particular bug, the program must be kept running while being fed a particular set of data. In those cases, having the ability to view variable values as they change without halting the target is a great asset.
  • OS-Aware Feature Supports FreeRTOS 
    The GDB server will automatically detect the presence, type, and configuration of an OS by querying the application’s symbol table for identifying characteristics. Using these discovered symbols, the debugger can traverse the kernel’s internal data structures to enumerate the available threads and their corresponding execution context. This information is then used to dynamically populate the Eclipse views as the user navigates between the threads. Additional OS support is expected to be added soon.
  • Single-Wire Output (SWO) Debug Tools
    SWO Tools are natively integrated into NXP’s MCUXpresso software. By using Eclipse-based IDE's such as MCUXpresso or PEmicro's plug-in for ARM-based GDB IDEs, users can measure power consumption of their device in real time (FX only), monitor multiple variables and expressions in real time, use printf calls to be notified when specific events occur during the debug session, and use trace capture to log user-specified events and triggers. This allows much more insight into the operation of the user's code. 


System Requirements

FAQs
My Legacy Codewarrior, my Eclipse Codewarrior 10.2 or higher, or my other 3rd party software with PEmicro support will not detect my PEmicro hardware tool or fails to connect to the target board. What can I do to fix this?
When using the multilink with your software tools, I get an error $8882 when it attempts to firmware update every time. This setup used to work with older multilink but not with the new multilink. What is going on?
I launched the command-line CPROGxx flash programmer, saw a window flicker up, and then disappear. How do I know what happened?
The connection assistant dialog indicates that my Multilink or Cyclone is undetected even though I have connected the hardware to my USB port. What should I do?
Why do I see the Power Dialog warning when trying to debug or flash program my chip in PROG, ICD, UNIT, or 3rd party software like Codewarrior? How can I prevent this from happening?

Models/Part Numbers

Multilink debug probes work with development software from PEmicro, NXP, and many other third parties. PEmicro offers three models of Multilink:

Multilink ACP (part# USB-ML-ACP) supports a wide variety of ARM Cortex-M devices. Please view PEmicro's ARM device resource page to find supported ARM Cortex-M devices by manufacturer. 

Multilink Universal (part# USB-ML-UNIVERSAL) supports those same ARM devices, as well as many NXP 8-/16-/32-bit devices. Please view our available Flash Algorithms resource page for a list of available algorithms. Feature sets are the same for the Multilink Universal & Multilink ACP.
