Tiny2040 8mb newer firmware than 1.18.4


Is there a newer micropython firmware for the tiny2040 with 8mb than 1.18.4? looks like all other firmwares are 2mb only.


I’m also wondering about that?

I’ve e-mailed tech support about this. I should get a reply Monday or Tuesday.

The Tiny 2040 board in releases is configured to use 8MB flash. It’s just… not terribly clear about that.

So maybe something else is wrong… if I try to use the latest firmware on it then it’s not detected…

(sensors) ido@nl-sensors:~/git/pico/pico $ cp ~/pimoroni-tiny2040-v1.20.1-micropython.uf2 /media/ido/RPI-RP2/
(sensors) ido@nl-sensors:~/git/pico/pico $ ls /dev/ttyA*

As soon as I put the 1.18 8mb one it works fine:

(sensors) ido@nl-sensors:~/git/pico/pico $ cp ~/pimoroni-tiny2040_8mb-v1.18.4-micropython.uf2 /media/ido/RPI-RP2/
(sensors) ido@nl-sensors:~/git/pico/pico $ ls /dev/ttyA*
/dev/ttyACM0  /dev/ttyAMA0

Ok, that means that the 2mb version uses the standard PICO uf2.
It makes sense once you know. ;)

120.2 is working OK for me on my Tiny 2040 8mb. Tony’s code runs OK on it too.
