I spent half a day on setting up the buildroot , a whole day on developing lcd and kbd drivers and another whole day on fixing some bugs.
Now it runs linux on picocalc.
Image for test:
If you use the version with spi nand, please erase the spi nand. Otherwise, the board will boot from the spi nand, not the sd card
Great
Will there be a source code ?
I admire your mental illnesses!
The Lyra doesn’t have wifi/bt, correct? I wonder if they could be added via the USB OTG connector on the board, and adding a wireless dongle? How fully featured is Linux on the device? From what I could tell researching online, it appears to support a headless Ubuntu build. Without network connectivity I’m wondering how updates would be supported or applications could be installed?
This is really cool!
I will upload the code to github.
Here’s the image for test:

I plan to use an esp32c3 as a spi wifi adapter. It can be plugged into the picocalc’s sd card socket.
I think it can be used to play NetHack.
Now Pico-8 runs on PicoCalc
you are a magician! 
can you please press ‘ctrl + p’ to check LA? seems like 15fps 
Is this on a 2040 or 2350?
this is on luckfox lyra.
Yes but which pico hardware is this running on? The included Pico H or a Pico 2? Asking because of the framerate.
It’s not running on Pico hardware. @hisptoot has swapped it for a Luckfox Lyra, which is pin-compatible with the Pico but runs beefier ARM cores.
Info on the Lyra can be found here.
I updated the image.
Now it supports tmux, pico8_dyn and prboom. Retroarch still has some problems, maybe related to the config.
And the screen’s spi bus is overclocked to 80Mhz.
Great job, I’ve already ordered the Luckfox Lyra. Linux is the way to go 
Can we see a shot of the Luckfox Lyra in situ ?. Will MMBasic work on this ?
Would that fit with the mipi display connector on the Lyra?
Looks like it is this?

An adapter for a Lychee Pi Zero.
Would there be drivers for it to work on the Lyra?
From what I could find, it appears to be a RTL8723BS chipset. Sounds like Linux drivers exist, but it might also be an old module that doesn’t support BLE, and is probably an older Bluetooth standard. The physical size worries me too, though maybe it could be connected with a flexible extension ribbon adaptor. I dont think I’ll take the risk, but if anyone else gets something like this working, I’d be happy to hear it.
