Does any psplink version support extended 32 MB on Slims? Because I got this exception:

Code:

Bur psplink refuses to access 0x0AXXXXXX memory addresses.

Any clue anout this?

Lol, what kind of code is that? :D

OFW code, namely sceHVUI_Module, as seen in the exception :P Anyway, those registers are rarely used.

it's in file "decodeaddr.c"
http://svn.ps2dev.org/filedetails.php?repname=psp&path=%2Ftrunk%2Fpsplinkusb%2Fpsplink%2Fdecodeaddr.c&rev=0&sc=0

Code:

static struct mem_entry g_memareas[] =
{
{ 0x00010000, (16 * 1024), MEM_ATTRIB_ALL, "Scratchpad", 0 },
{ 0x40010000, (16 * 1024), MEM_ATTRIB_ALL, "Scratchpad (uncached)", 0 },
{ 0x04000000, (2 * 1024 * 1024), MEM_ATTRIB_ALL, "VRAM", 0 },
{ 0x44000000, (2 * 1024 * 1024), MEM_ATTRIB_ALL, "VRAM (uncached)", 0 },
{ 0x08800000, (24 * 1024 * 1024), MEM_ATTRIB_ALL, "User memory", 0 },
{ 0x48800000, (24 * 1024 * 1024), MEM_ATTRIB_ALL, "User memory (uncached)", 0 },
{ 0x88000000, (4 * 1024 * 1024), MEM_ATTRIB_ALL, "Kernel memory (low)", 0 },
{ 0xA8000000, (4 * 1024 * 1024), MEM_ATTRIB_ALL, "Kernel memory (low uncached)", 0 },
/* Don't use the following 2 on a 1.5, just crashes the psp */
{ 0x88400000, (4 * 1024 * 1024), MEM_ATTRIB_ALL, "Kernel memory (mid v1.0 only)", 1 },
{ 0xA8400000, (4 * 1024 * 1024), MEM_ATTRIB_ALL, "Kernel memory (mid v1.0 only uncached)", 1 },
{ 0x88800000, (24 * 1024 * 1024), MEM_ATTRIB_ALL, "Kernel memory (high)", 0 },
{ 0xA8800000, (24 * 1024 * 1024), MEM_ATTRIB_ALL, "Kernel memory (high uncached)", 0 },
{ 0xBFC00000, (1 * 1024 * 1024), MEM_ATTRIB_ALL, "Internal RAM", 0 },
{ 0, 0, 0, NULL }
};

and these two lines

Code:

{ 0x08800000, (24 * 1024 * 1024), MEM_ATTRIB_ALL, "User memory", 0 },
{ 0x48800000, (24 * 1024 * 1024), MEM_ATTRIB_ALL, "User memory (uncached)", 0 },

change to

{ 0x08800000, (24 * 1024 * 1024 + 32 * 1024 * 1024), MEM_ATTRIB_ALL, "User memory", 0 },
{ 0x48800000, (24 * 1024 * 1024 + 32 * 1024 * 1024), MEM_ATTRIB_ALL, "User memory (uncached)", 0 },
