I'm trying to use the function "xscale_sram_malloc_user" on PXA270 on Linux (patched by intel mainstone, http://ftp.linux.org.uk/pub/linux/people/arm/people/xscale/mainstone/12-29-2004/). I want to allocate a block from internal SRAM of pxa270, and use in user space. So I am going to use the API "void *xscale_sram_malloc_user(size_t size, u32 virtual_sram_base, u32 pid)" But I cannot know that how can i get virtual_sram_base "virtual_sram_base - the virtual address of sram_base as assigned by a call to mmap." WhatI should do?
Thanks for your inquiry. The PXA270 processor is now owned and supported by Marvell (see: http://www.marvell.com/). This is a change that took effect in 2006. You might check their web site or support groups for more information.
