Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

J-Link replacement with Raspberry Pi Pico?
Can Raspberry Pi Pico replace J-Link? I saw PicoProbe project, installed and wired for it, but pyocd stucks with "Waiting for a debug probe to be connected..." and nRF Connect Programmer fails with error "Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device."

Help debugging RP2040 using J-Link and OpenOCD
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.

New Product from Raspberry Pi: Raspberry Pi Debug Probe: a plug-and-play debug kit for $12
That's cool, but does it do anything you can't already do with just another Pico running picoprobe? (like this)

rp2040, boot from ram(no flash), swd
I need to boot rp2040 from ram (no flash), which I have tested with the picotool (with USB) and picoprobe (with swd+gdb load) and I can boot from ram and flashing a LED.

Anyway to use a RP pico as an stlink clone?
Yes -- the Picoprobe firmware is what you're after.

What're my debugging options without a raspberry pi?
There's also apparently a way to use the other core of a Pico as a debug programmer: https://github.com/majbthrd/pico-debug/ but that's pretty advanced.

Raspberry Pico: Simple Debugging with just one Device
This blog pot continues the Pico setup series and will detail how to setup a fully working debugger in VS Studio Code. Keep in mind that ultimately the steps are based on explanations from pico-debug project, and wizio-pico, but the setup is complex so I wrote a summarizing blog article. Follow along and you will be debugging your Pico C programs with the press of a simple launch button.
