The cpu/6502/ directory is used for targeting 6502-based machines using the cc65
|
|
|
|
|
compiler (http://www.cc65.org/). In almost all cases it is preferable to go for
|
|
|
|
|
a recent snapshot instead of the latest official version. The most recent cc65
|
2008-06-13 00:15:50 +02:00
|
|
|
snapshot is available at ftp://ftp.musoftware.de/pub/uz/cc65/snapshot/.

The Contiki network configuration for 6502-based targets is loaded from a binary
|
|
|
|
|
configuration file (by default named contiki.cfg). It has the following format:

|
|

The build for 6502-based machines includes the 'disk' make goal which creates a
|
|
|
|
|
bootable floppy disk image containing the project binary, a sample configuration
|
|
|
|
|
file and the Ethernet card drivers.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The 6502-based targets do in general not support keyboard input or screen output
|
|
|
|
|
through stdin, stdout and stderr.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The build for 6502-based machines supports so-called high-level configuration
|
|
|
|
|
macros which allow to customize Contiki on a per-project basis. They are set
|
|
|
|
|
in form of a comma-separated list as value of the make variable DEFINES on the
|
|
|
|
|
make command line. The value of DEFINES can be saved with the 'savedefines' make
|
|
|
|
|
goal. The values of the high-level configuration macros are not tracked by the
|
|
|
|
|
build so a manual rebuild is necessary on any change. The following high-level
|
|
|
|
|
configuration macros may be set:
|
|
|
|
|
|
|
|
|
|
MTU_SIZE
|
|
|
|
|
- Default: 1500
|
|
|
|
|
- Purpose: Set the Maximum Transfer Unit size.
|
|
|
|
|
|
|
|
|
|
WITH_LOGGING
|
|
|
|
|
- Default: 0
|
|
|
|
|
- Purpose: Have log_message() write messages to the screen.

|
|
|
|
WITH_BOOST
|
|
|
|
|
- Default: 0
|
|
|
|
|
- Purpose: Significantly improve troughput on sending full sized packets by
|
|
|
|
|
splitting them thus workarounding the "delayed acknowledge".
|
|
|
|
|
|
|
|
|
|
WITH_FORWARDING
|
|
|
|
|
- Default: 0

|
|
|
|
|
WITH_DNS
|
|
|
|
|
- Default: 0
|
|
|
|
|

|
|
|
|
|
|
|
|
WITH_PFS
|
|
|
|
|
- Default: 0
|
|
|
|
