Reduced stacksize.
2007-11-27 12:24:03 +00:00
# This file should be identical to the file '<cc65>/doc/apple2.cfg' with the
# following exceptions:
# - Reduced stacksize: Contiki is designed to use extremely little stack.
# The applications coming with Contiki run even with a $100 byte stack.
# - Expanded RAM size: Allow applications to overlay BASIC.SYSTEM if needed.
# In that case the binary must be loaded with the ProDOS 8 loader available
Starting with the cc65-snapshot-2.11.9.20080316 the Apple2 C-library supports placing code in the Apple2 Language Card by choosing the code segment 'HIGHCODE'. By default the memory area 0xD400 - 0xE000 is used for HIGHCODE. If the application doesn't need the ProDOS 8 QUIT code then the memory area used for HIGHCODE may be extended to 0xD000 - 0xE000. Contiki now leverages that feature to place process.o, etimer.o and uip_arp.o in HIGHCODE. These files were carefully chosen as: - they are necessary for all Ethernet apps - their size doesn't depend on configuration macros - they fill the available space nicely (with a little reserve for changes in the source or the compiler)

# at: ftp://ftp.musoftware.de/pub/uz/cc65/contrib/loader-1.3.zip
# - Expanded LC size: Allow applications to overlay the ProDOS 8 QUIT code.
# In that case the binary must reboot on exit. There's a ProDOS 8 loader
# variant available at the URL above that does just this.
