Guide for building on an embedded platform #116
Description
I'm interested in building pForth for an ARM Cortex-M micro-controller. I've looked at the existing Makefiles in platforms but I can't figure out from that how to create one for, say, an Electro-Smith Daisy, a Raspberry Pi Pico or a Teensy. The Daisy and Pico have full C/C++ SDKs that run on Linux (and MacOS and Windows). I think there's an SDK for Teensy as well but I've only used the Arduino IDE with it.
How would I go about doing such a port? I am probably only going to need the CORE and BLOCK word sets in the final build, but I will eventually want to write a Forth-style assembler.

Have you tried the cross compiling docs here?

Please let me know if they do not work or you have questions.
Also how is the memory fit?

The base Pico has 264K bytes of RAM and at least 2 MB of flash - some variants go as high as 16 MB of flash. The Arduino IDE lets you configure some of the flash as a filesystem.
The Teensy (4.1) has 1 MB of RAM and 8 MB of flash. The Daisy Seed has 64 MB of RAM and 8 MB of flash.
