jlinkx64sys seems to be related to Java and specifically to the Java Development Kit (JDK) tools. Here are a few key points about it:

Whether you are bringing up U-Boot on a new Xilinx Zynq MPSoC board or patching a legacy μC/OS-III system, remember: the quality of your debug session is only as good as the robustness of the interface between your x64 host and the target silicon. jlinkx64sys provides that interface—efficiently, reliably, and at speeds that turn weeks of debugging into hours. jlinkx64sys
High-speed JTAG requires stable target clock. If the target CPU enters an invalid PLL state, jlinkx64sys can issue an adaptive clocking fallback (-speed auto) to establish basic communication before reflashing. jlinkx64sys seems to be related to Java and

When you install a typical J-Link software and documentation pack (v7.90+), the jlinkx64sys infrastructure includes:
