Can battery-backed RAM be increased on the BL2600 SBC?

I need more bbram space for a project I am working on.

In the StdBios.c file there is:
#define BBROOTDATASIZE 0x1000

Can that be changed to:
#define BBROOTDATASIZE 0x2000

Would this cause memory problems?

I think you're limited to how much battery-backed memory is mapped to the root address space.

Use _xalloc() to allocate battery-backed space in extended memory. You'd use xmem2root() and root2xmem() to copy data to/from that space.
