Need to finish QSPI flash and then create a boot loader so RustWorks can be flashed to external flash.
Potentially useful links:

• flashAlgorithm docs: https://www.keil.com/pack/doc/CMSIS/Pack/html/flashAlgorithm.html
• flashAlgorithm for RP2040: https://github.com/rp-rs/flash-algo

Todo:

• Read external flash
• Write external flash
• Flash algorithm implementation so that cargo flash can access external flash (done in willemml/rsworks-flash-algo)
• Make probe-rs and cargo-embed use flash algorithm
• Enable writing external flash using dfu-util

Hello, I'm trying to use rustworks on my numworks (n110) from my Raspberry Pi 4 (with Raspberry Pi OS, I don't know if it matters) but when I run cargo make dfu
I get the following error message:

[cargo-make] INFO - Execute Command: "dfu-util" "-d" "0483:df11" "-a" "0" "-s" "0x08000000:leave" "-D" "target/thumbv7em-none-eabihf/debug/rustworks.bin"
dfu-util 0.9

dfu-util: File size is too big: Success
[cargo-make] ERROR - Error while executing command, exit code: 74
[cargo-make] WARN - Build Failed.

Before running rustworks, I installed dependencies:

rustup target add thumbv7em-none-eabihf
sudo apt-get install gcc-arm-none-eabi binutils-arm-none-eabi 
sudo apt-get install dfu-util

rustup component add llvm-tools-preview
cargo install cargo-binutils
cargo install cargo-make

Then I cloned rustworks repository and ran cargo make dfu .

The bin file (target/thumbv7em-none-eabihf/debug/rustworks.bin) has a size of 2, 28 GB which seems effectively too big to flash on the numworks.

did I do something wrong?

Android emulator?
Windows emulator?
Linux emulator?
iOS emulator?

This would be awesome to have because it would make it so that we could make rustworks work in a fully open source platform, like, for example, creating our own calculator hardware (fully open source unlike Numworks).

Ideally the OS should not depend on an allocator for any core features (e.g. displaying text)

using branch split (or master) I get ERROR - Task dfu not found.

Any idea why? Thanks!

Everything should be unit tested somehow, I am not entirely sure how to do this yet for the embedded part though.

All code (especially code that deals with complex thing specific to embedded development like modifying registers) should be documented with comments explaining what's going on to make it easier for other people to understand and contribute to the project.
