re: #1,
in a sense, the stuff you downloaded *is* there, but IC doesn't know
how to access it until you re-download. So yes, each time you restart
IC, you must re-download your project.
re: #2.
there are not good reporting tools for memory usage. i think the
'mem' command reports free memeory in the IC application, which isn't
that relevant.
the way that the 6811 memory is partitioned is follows, there is
basically 16K for user code. There is no way to free up more space
without recompiling IC. Here are some more details.
user program object code + user global variables 16320 bytes available
runtime OS 7936 bytes used
stack space for user processes 6656 bytes used
buffer for interaction process 256 bytes used
buffer for printing 256 bytes used
When downloading your code, IC tells you how many bytes are going
down. You've got 16,320 available.
