now I am using ds5250 to do RSA algorithm.
I have 512k externel SRAM.
off-chip code memory start:0x00000 size:0x40000
off-chip xdata memory start:0x0400 size:0x1000 start:0x40000
the first xdata memory configuration is to do MAA.
but when compile,its xdata address space overflow.
and it seems that my second xdata memory is not used,it only uses my
first xdata memory,and then xdata memory space overflow.
but if i do not config the first xdata memory,the RSA algorithm does
who can help me?thanks
"standard" XDATA can never exceed 64K - so how are you configuring
yours for 512K?
i am using Dallas 5250.
it can extend external SRAM to 4M.
In my configuration,I use 256k for program memory and
256k for data memory,and the 0x0400-0x1400 xdata memory
is just for MAA.

The chip can do it, but how are you configuring he
tools to use it?
