xboot VS toaruos

This tiny bootloader-sized OS runs on H3: https://github.com/xboot/xboot

Most Allwinner devices use U-Boot as a second stage bootloader, however U-Boot could not be found on the flash-system. Instead, references to “XBOOT” and “XTAB” were found in the flash, though this did not match any known bootloader such as https://github.com/xboot/xboot.

Another interesting project to checkout is klange’s toaruos https://github.com/klange/toaruos

In case it's not clear, PonyOS is a joke reskin of my serious OS project, ToaruOS. PonyOS gets a new release every April 1st. All of the libraries and applications in ToaruOS are in-house things I built myself - the whole OS is "built from scratch". PonyOS adds ponysay, which is an external app originally written in Python - and in previous releases of PonyOS I shipped the Python version alongside a port of Python 3.6. This release, though, comes with a port to my own language, Kuroko, which is a dialect of Python - a lot of what went into building the PonyOS release this year was getting ponysay to work well.

There is no correct way to use inline assembly here. You need a stub written in assembly that will save those registers to the stack and pass a pointer to a handler written in C. You may also want to define a struct that matches the stack layout to make it easier to access the stack contents. This is not my code. If you want to use this code in your OS, you must follow the license requirements.

Here's a good example, although it's 64-bit instead of 32-bit.
