Overview
Have a J-Link BASE and want to get an upgrade?
The JTAG/SWD debug probe J-Link BASE, with its USB interface increases productivity with the J-Link BASE Upgrade. Already supporting a broad range of microcontrollers, J-Link BASE can already work on multiple CPUs, supporting 8051, PIC32, RX, ARM7/9/11, Cortex-M/R/A, RISC-V with a download speed of up to 1Mbytes. It also supports unlimited breakpoints in flash memory (with an additional license) and has built-in VCOM functionality.
With the J-Link BASE Upgrade, users can also get J-Flash / J-Flash SPI software, the Ozone Performance Debugger & Analyzer, RDI & RDDI.
Further advantages
The J-Link BASE to PLUS upgrade comes with a software bundle that includes the J-Flash / J-Flash SPI license, software to program EEPROM and flash chips in ARM systems and a J-Link Unlimited Flash Breakpoints license. Included is also the Ozone J-Link Debugger & Performance Analyzer, Monitor Mode, J-Link ARM RDI / RDDI license and the license pack for the RDI / RDDI interface.

Questions and Answers
-
Can I Use J-Flash Immediately After Upgrading BASE to PLUS?
Yes. The upgrade activates J-Flash for secure production programming of internal and external flash devices, with no further purchase. -
What Is the Benefit of Unlimited Flash Breakpoints?
It lets you set reliable software breakpoints in flash. This is critical when debugging applications that run entirely from on-chip flash. -
Is the Upgrade Suitable for RISC-V Development?
Yes. J-Link PLUS supports Arm, RX, PIC32 and RISC-V devices. -
Does the Upgrade Enable Real-Time Transfer (RTT)?
Yes. RTT is supported on J-Link PLUS, providing real-time logging and data exchange without halting the target or wiring extra UARTs. -
Why Do Professional Engineers Choose to Upgrade to PLUS?
Engineers value the bundled licences, broad CPU/IDE support and production readiness. Compared with higher-priced probes, PLUS balances features with efficiency. -
What Is the SEGGER J-Link Upgrade BASE to PLUS?
It is a licence upgrade that turns a J-Link BASE into a J-Link PLUS. It unlocks features such as Unlimited Flash Breakpoints and J-Flash programming. -
What Licences Are Included with the J-Link PLUS Upgrade?
The upgrade adds Unlimited Flash Breakpoints and J-Flash licences, both essential for engineers working with flash-only microcontrollers. -
How Does J-Link PLUS Compare with More Advanced Probes Such as J-Link PRO or ULTRA+?
J-Link PLUS gives fast debug and production programming at up to 15 MHz. J-Link PRO and J-Link ULTRA+ offer higher interface speeds and advanced trace features, at a higher price.
