Exploring RISC-V Options: the RP2350 (Part 3 -- No Drive to Deploy)

It was bound to happen. The Seeed Studio RP2350 is not connecting to the Arduino IDE.

I'll go out on a limb here and chalk this up to the boot loader having an issue after I tried to get it to spit out serial data or maybe it was because I was trying to get the Arduino IDE to enter it's new "debug mode" via the boot loader.

Personally, this is why I prefer to develop with background debuggers (SWD, JTAG, jLink, PICKits, etc.). The BDM access on the old 9s12 was one of the key reasons I moved to the 9s12 after the 68HC11 and its BUFFALO serial monitor Alas, I'm stuck with the boot loader on the RP2350.

The error I'm getting on the Arduion IDE looks like this:

Error message generated by the Arduino IDE.

Thankfully, the RP2350 developers added a hard reset feature for the boot loader. Press the B button, hold it, then briefly tap the R button, then release both:

Hard reset the board using the B and R buttons. Hold the B button, and then hold the R button briefly. Then release both.

Once the hard reset is done, the board will show up as a flash drive on your computer and then the Arduino IDE will be able to refresh it.
