Question about Virtual memory limitations in WinCE

Hi,

While I was going through the code for the bootloader, it was mentioned that
the virtual memory cannot be more than 512MB. Is this limitation because of
winCE, which can handle only a maximum of 512MB physical memory. Or does it
have any other reason?

If we have to increase this limit, is there any possible way to do it.

Warm Regards,
Naveen Atmakuri.

The 512 limitation is a limitation of statically mapped addresses in the
kernel. Addresses needed by the kernel, which would include RAM and ROM are
statically mapped in OEMAddressTable. Addresses not needed by the kernel do
not need to be statically mapped.

You are calling this memory, but it is addresses, which includes addresses
of the CPU and peripherals.

You can wait until WinCE 6, where the limit is 2GB *per process*.
