I bought a Pinecil so I could run it off a battery. I really came to appreciate the excellent temperature control and rapid heating, and use it instead of my soldering station for jobs away from the bench.
I have felt absolutely no need to touch the firmware. I try to forget that it is more powerful than my first three personal computers combined. Plug in, turn on, get hot. It meets my needs and exceeded my expectations. I suppose I could run a website from it if I wanted to make a point but as long as it doesn't require wifi and phone home to verify the license and leak my biometric data I expect to use it until I wear it out.

Jlink is closed source.
Better use dirtyJTAG on an rp2040.
Agree RP2040 / RP2350 is great for debug and UART access! I wrote[0] about using picoprobe with this device as well.
I tried to use picoprobe to debug an nrf52 chip, it failed to even detect it.. All that’s officially supported is using it to debug a raspberry pi, and maybe if I added 100Ohm resistors to the lines I would have had better luck, but.. alas

I've literally got a Pi Debug Probe and a nRF52840 dev board on my desk, so I gave it a shot - and it works just fine. Make sure the core is awake when you try to connect for debug, or connect under reset; SWD goes to sleep with the rest of the chip.

The Pi Debug Probe is a generic DAPlink probe, and will work for pretty much any Cortex-M part. I routinely use mine for debugging STM32 parts.
JLink + Segger Ozone is so, so good though.
Supper fast to flash and really nice debugger.
It's been a long time since I messed around with this stuff, proprietary JTAG devices and debuggers used to be leaps and bounds ahead of open source ones. Is it still the same?
Good to see an "organic" J-Link + RISC-V use case :)

Doesn’t look like openocd is getting dirtyjtag support any time soon, the PR has stalled since 2003 it seems https://review.openocd.org/c/openocd/+/7344
Why that over the debug probe firmware?
