[...] the original idea was that the application could just point the uip_appdata pointer to wherever the data was, but we then changed it so that the data actually had to be copied into the uip_aligned_buf buffer. So, yes, the network device driver should only need to read from this buffer. [...]
This change removes comments on the possibility of uip_appdata pointing somewhere outside the uip_aligned_buf. And it removes code in the SLIP drivers not necessary anymore.
Additionally it makes code in a SLIP driver optional that takes care of the Microsoft-specific CLIENT / SERVER / CLIENTSERVER chat.
After all there's no momentum for a W5100-based Ethernet solution on the ATARI. So I revert to static linkage of the CS8900A driver as this improves program load times.
The tests are recognized as success when a return value by
rpl_ns_num_nodes(), the number of entries in the nodelist, tells all the
routes for the nodes in the network are installed.
There are eight nodes in addition to one root node. Therefore, the value
for test success should not be eight but nine since we have to take into
account an nodelist entry for the root.
Fixed two errors in Zigbit's makefile:
-Compiling "frame.c" here is not necessary (already done in radio's makefile) and brings up an error. Removing it.
-Fixed undefined reference to "link_stats_input_callback" in "../../core/net/ipv6/sicslowpan.c:1521". Module "core/net" was missing.
Compiling working now.
tsch_security_secure_frame() returns the length of MIC in case of
success. Otherwise, it is supposed to return 0. There was one case where
it returns 1 in an error handling block.
I just tried to compile this platform for my Zigbit mote (AT86RF230) here in a hello-world example, but it didn't work.
I reviewed this makefile and found that the request to compile "frame.c" was not necessary and bring up a missing error:
"make: *** No rule to make target `obj_avr-zigbit/frame.o', needed by `contiki-avr-zigbit.a'. Stop."
Frame.c is already inserted in radio's makefile.
Another problem was the undefined reference created by the missing module "core/net":
"contiki-avr-zigbit.a(sicslowpan.o): In function `input':"
"contiki/examples/hello-world/../../core/net/ipv6/sicslowpan.c:1521: undefined reference to `link_stats_input_callback'"
Both solved now. Hope it helps anyone else.
