Pimoroni Tiny 2040 (8mb), flash for use as debug probe?

I have a couple Pimoroni Tiny 2040’s sitting here doing nothing. I had a thought to set one up as a Debug Probe.
Raspberry Pi Debug Probe (pimoroni.com)
The real deal is out of stock, so why not have a go? The wrinkle is mine are both 8mb and the images (uf2 files) I’m finding online are for a stock 2mb RP2040.

Any ideas?

I don’t think it actually matters, I’ve run the PicoProbe firmware on what I’m pretty certain is an 8MB Tiny 2040 and it seems to work fine. I think in this case it just doesn’t know there is extra memory to access, it would be more of an issue if you needed 8MB but only had 2MB.

I was thinking along the same lines, just wanted to see what others thought.
Might try it on a Pico first, just to make sure I have it all figured out?

The memory chip is physically bigger on the 8MB Tiny.

The 2MB version actually says 2MB on it.


Ah, I didn’t know that actually. It seems odd to mark the 2MB boards but not the 8MB boards, and the lack of markings always makes me wonder which version I have. In that case I’ve definitely used my 8MB Tiny 2040 as a picoprobe and it worked just fine.

Ditto, thats why I asked in another thread.

Tiny 2040, 2MB or 8MB? How to tell which it is? - Support - Pimoroni Buccaneers

This is the 8MB

Ah, neat. I don’t know why they wouldn’t use the little space between the pins in the bottom left to mark it though, it seems to me that an explicit note of the capacity would be sensible.

But anyway, yes, because it is so teeny it makes a great we picoprobe compared to a full-sized pico or pico lipo.
