Foenix targets for VBCC

Foenix A2560 build target for VBCC that produced ELF binaries.

Install

The contents of the vbcc folder should be copied into your VBCC installation.

Usage

Syscalls are availble by adding the following to your code:

#include <mcp/syscalls.h>

An ELF executable can be produced using the following command:

vc +a2560-elf -o hello.elf hello.c

If on a Windows machine, use the following:

vc +a2560-elf-win32 -o hello.elf hello.c

An srec28 executable can be produced using the following command:

vc +a2560-s28 -o hello.s28 hello.c

If on a Windows machine, use the following:

vc +a2560-s28-win32 -o hello.s28 hello.c

Build

For your convenience the libraries are prebuild in the vbcc directory and can be copied to you VBCC install. However, if you need to tweak the code:

  • startup.s configures the entry point, defines syscall function, and calls sys_exit when main returns.
  • io.c implements vbcc io stub funtions to enable stdio.
  • syscalls.c implements sys_* kernel function via calls to syscall.

To build:

cd src
make

# to install into ../vbcc/targets/a2560-elf/lib
make install
