Memory nodes
4 messages in this thread
I've got a real problem here. I Only have 512 K of Chipmem. When my A500
has finished booting I hav about 250K of chipmem free.
I think the problem is that my ramexpansion is not auto-configurable (It's
self-built). I configure the memory with a program that simply adds a
memnode into exec's lists. At the time of booting, however there is no
Fastmem. Probably exec puts some vectors and stuctures in chipmem but I
can't imagine exec needing roughly 260K for all that.
I tried to configure the Fastmem by using the coldcapture vector but so far
I haven't succeeded.
Any ideas?

Quinten,
Move your program that adds the memory to the top of the
startup-sequence; however, be aware, that some things simply must go into
CHIP RAM such as the display lists.

Don, that program is the second line in my startup-sequence. The thing is,
that lots of chipmem is being used the system. So What I'm looking for is a
program that will bind my memory into the system to survive a reset so that
the system will find it before booting and put it's stuff in there. (Hints
of how to accomplish this would also do.)

Quinten,
The only thing that I know of that will "bind" the memory before
bootup is autoconfig…and as you say, your board doesn't have that.
