A raspberry 3 OS

Support:

  1. UART
  2. Framebuffer
  3. update over serial
  4. Qemu

UART

Using GPIO 14 and 15

update over serial

You can update a kernel that is connected a given TTY with TTY=/dev/MYTTY make update_serial

This is mainly usefull for kernel running on a real board but to use it with QEMU, you have to modify the serial opt to be -serial pty

and then TTY=/TTY_VERBOSED_BY_QEMU make update_serial

QEMU

You can test it with make run

Qemu with a debugger

make debug

Install on sdcard

Create a FAT32 partion and copy kernel and kernel8.img
