How to use all of SRAM?

Rabbit
1

I have an RCM4010, which has 512k of SRAM.
However, I can’t use more than about 16k of it… when I declare
static protected char data[1024*20]; //20k
I get an “out of variable data space” error, yet this is far less than 512k.

How can one use ALL 512k of SRAM?

Thanks,

Lookup the keyword xmem is how the 3000 series do it; not sure on 4000 series.

Yeah, but this doesn’t allow you to store stuff there between power cycles & resets.
xalloc() just grabs a chunk of memory from the pool, there’s no way to spec the address.
