Hi
The MCUXpresso help says that
"
Currently we have tested using:
J-Link debug probes (USB and Ethernet)
J-Link firmware installed into on-board OpenSDA debug probe hardware (as shipped by default on certain Kinetis FRDM and TWR boards)
J-Link firmware installed onto LPC-Link2 debug hardware and LPCXpresso V2/V3 boards
"
Which versions/hardware revisions of JLINK are supported/needed?
J-LinkBecause we have the JLINK ultra V4 and MCUXpresso doesn't recognize it.

Hello,
I haven't find J-link ultra V4, while I checked J-LINK ULTRA+, it support
I.MX RT.
"J-Link ULTRA+ is a JTAG/SWD debug probe designed for Arm/Cortex. It is fully compatible to the standard J-Link and works with the same PC software.
"
Recommend ask segger technical support about ultra V4:
