The μLab at your desk – debug everywhere™

The successor to the widely used Marvell JTAG Probe III, the Marvell JTAG Probe V is supported by the Marvell Multi Core Debugger XDB 5.7.39 and newer; as always, it is recommended that users upgrade to the latest release. This high end and helpful – yet ultra-low cost – JTAG device has been upgraded with new features. The MJP-V is designed to work with a range of Marvell SOC and MCU, please see the userguide in the downloads section and the Marvell extranet for more information.


Marvell JTAG Probe version V does support JTAG and SWD (Serial Wire Debugging) debug interfaces, SWO (Serial Wire Output and 4bit TPIU). In addition to support SoC debugging, a range of new features were added including: informative display, 16 USER I/O on 4 programmable voltage rails, frequency generator, frequency measurement, and 3 analog input (0 – 5V). The host connections include USB 2.0/3.0 high speed and Gigabit Ethernet and provides a dual port Marvell Switch. The additional GbE connection enable debugging everywhere including serial terminal support over Ethernet with the Marvell Multi Core Debugger XDB.
