Hi, how can I build firmware for micropython for Tiny 2040?

I’m following the instruction here:

> **[raspberry-pi-pico-python-sdk.pdf](https://datasheets.raspberrypi.com/pico/raspberry-pi-pico-python-sdk.pdf)**

> 1770.69 KB

But this is specific to the pi pico, therefore I managed to build a firmware but with only 2MB storage

What do I need to do to build with the full 8MB storage?

thanks
