#description

This is a port of the ucore project to the ARM architecture.

'ucore' is a teaching operating system used by Tsinghua University. Project homepage: [http://ucore.googlecode.com].

Currently this port runs on the S3C2410X microprocessor, which is developed using an ARM920T core.

#source code organization

• 'arch' contains architecture dependent driver and boot code.
• 'lib' contains architecture independent library code.
• 'kern' contains architecture independent kernel code.
• 'tool' contains various tools such as GDB scripts and emulator configurations.

#current status

• Simple bootloader works, which can load elf kernel from memory.
• Output to UART works. cprintf works.
• Interrupt(IRQ) works.

#todo

• Implement memory management system.
• Implement syscall.
• Input from UART.
• Rewrite Makefile, make it DRY and more like original ucore Makefile.

#acknowledgment

• Most code is taken from the ucore project, of course.
• Boot and interrupt code is inspired by david leels davidontech@gmail.com.
• div64 code for arm is taken from the Linux kernel.
