debugprobe VS pico-examples

use the JECDB header to connect a SWD probe like a Picoprobe and debug the firmware

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."

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.

That's cool, but does it do anything you can't already do with just another Pico running picoprobe? (like this)

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.

Yes -- the Picoprobe firmware is what you're after.

And here's the repo for the picoprobe software: https://github.com/raspberrypi/picoprobe

Navigate to the Pico Examples repository.

I'm experimenting with the "pico/wifi/tcp_server/". It works as expected with a WPA2 secured network, however I can't figure out how to access a WP3 secured network. According to the Pico W datasheet the device supports WPA3. However the function cyw43_arch_wifi_connect_async doesn't seem to have the option to select WPA3. The supported options are CYW43_AUTH_WPA_TKIP_PSK, CYW43_AUTH_WPA2_AES_PSK, or CYW43_AUTH_WPA2_MIXED_PSK.

I connected the MPU6050 and Pico as shown in the wiring guide for the example code here and have also tried using a level shifter with this wiring setup.

There's an iperf opkg pkg, or is it just netperf (which works with fluent)?

Okay I abandoned both of those libraries and tried the simpler WS2812 example in the Pico SDK and I did get it working....finally.

For C++, you could look at the pico-examples on Github https://github.com/raspberrypi/pico-examples

I don't know what you mean. There are dozens of tutorials on the frontpage of google. And just straight up a bt folder of projects for the pico w in the rpi github at https://github.com/raspberrypi/pico-examples/tree/master/pico_w/bt. have you tried that? If you haven't, then you need to work on learning how to use google because people aren't here to do work for you. If you have tried this and it didn't work then reread my previous post and ask better questions.

I'm sorry I don't use the pico-sdk so I'm not 100% sure of which method it'd be. A short lookup in the pico-examples repository brought me to this.

The LED is controlled by a GPIO pin on the radio, not the RP2040. See https://github.com/raspberrypi/pico-examples/blob/master/pico_w/wifi/blink/picow_blink.c.
