I'm using two uPSD. One of them is master and the other is slave .

I use Keil C. There are no problem to work except one.

That is to declare a data type in slave .

If I declare a variables for using S2DAT in idata, It is no problem.

But I do in xdata, it does'n work.

for example

unsigned char xdata buff[10]; does'n work;

unsigned char idata buff[10] ; OK

There is no problem like that in master just slave .

How can I fix it.
