Even once you've got that handled, though, I'm not sure the JLink will be able to connect. The RP2040 uses a somewhat uncommon variant on SWD to communicate with its two cores; not all debug probes support this. If you can't get the JLink to work and you have a spare Pi Pico around, you can use the Picoprobe firmware to turn the extra Pi into a DAPlink-compatible debug probe.
